Stainless steel has been one of the greatest inventions in the history of mankind. It is a kind of metal alloy made from the combination of steel and other metals like nickel and chromium. What makes stainless steel stand apart from the rest of the materials is its versatility in countless applications. The diverse range of grades allows it to accommodate various applications across many different industries.

Here are 7 things to consider while choosing a right stainless steel grade:
Not all grades of stainless steel are weldable. Depending upon certain grades, welding can lead to problems such as intergranular corrosion, hot cracking and stress corrosion cracking. In case your products needs welding, you need to choose stainless steel grade that is weldable. Austenitic stainless steel grades such as 304L, 347 ce be used for welding due to lower carbon levels. Ferritic stainless steels such as grade 430 or grade 439 are also readily weldable. Martensitic stainless are generally not suitable for welding. Extra care needs to be taken when welding stainless steel to ensure that the mechanical properties of the metal are not compromised during the welding process.
Though stainless is known to have corrosion resistance, various grades of stainless steel have varying levels of corrosion resistance. Austenitic stainless steel like Grade 304 and 316 is the most sought after for corrosion resistance because of high amounts of chromium and molybdenum, respectively. Ferritic stainless steels and martensitic are generally more affordable than austenitic stainless steel because they have less nickel and sometimes less chromium than austenitic stainless steels, which can result in a loss of corrosion resistance. They are suitable for applications that involve the indoor use of stainless steel as this limits exposure to weather and other corrosive elements.
Most grades of stainless steel can be machined, however, it is very susceptible to hardening. The machining process must be optimized to work at a rate that helps alleviate this issue, and the tools used for machining must also be kept in good working condition. Similar to carbon steels, sulfur can be added to increase machinability; grade 303 is an example of this. It is very similar to grade 304 except that sulfur has been added to it for machining purposes. Grade 416 is example of a ferritic stainless steel with added sulfur.
If the stainless steel is going to be subjected to heat it imperative to know how the product properties will be affected. Grade 440C and 17-4 PH, are heat treatable stainless steels.
The quality of stainless steel depends on various factors and one of the most important factors to consider while selecting the stainless steel is the strength. The strength varies from varies between different grades. Martensitic stainless steels, like grade 440C and precipitation hardened stainless steels, like grades 17-4 PH and 15-5 PH have the best strength. Austenitic stainless steels comes second on the scale of strength. Duplex stainless steels can provide ferritic stainless steel properties while still maintaining a ductility and a toughness close to austenitic stainless steels.
If the application of stainless steel castings requires good formability, austenitic grade such as 304 or a ferritic grade such as 430 are the best. Martensitic group of stainless steel tend to be brittle and are not readily formable.
In order to choose a good stainless steel grade all the above considerations are important but the most important one is cost effectiveness. Your industry needs to have stainless steel applications that are profitable, match your intended environment and have high performing for a long term. Though most grades of stainless steel require negligible maintenance, you still need to account it depending upon the harsh, cold or corrosive environment it is expected to work in.
Here are some of the tried and tested applications so you know which stainless steel grade to use for your industry.

When sourcing steel for your business, the bottom line often comes down to how to find a quality product at the right price and at the right time. Sourcing is far more intricate than the mentioned. Selecting a reliable and top steel supplier can be a game-changer for your business. In a nutshell, there are 5 qualities you should look for when searching for a steel supplier.
1. Global Experience + Local Expertise
Global sourcing has unique advantages that cannot be replaced, specifically when it comes to steel. As shown in this latest steel market outlook report, China accounts for over 50% of the world's steel production. Many steel users import their supplies from China, India, and other key steel-producing countries for maximized benefits. Getting steel supplies overseas is an increasingly popular trend, especially for those who need consistent and large volumes.
That being said, it's not easy to find global suppliers who can also meet your needs from a local scope.
Firstly, the most common issue, the language barrier, comes to mind. Also, overseas companies may not be that well versed in the local market. That's why it's important to select a supplier that has local team members with in-depth knowledge about the market, preferably a local office.
CUMIC Steel, led by globally experienced management, has a culturally diverse sales team in multiple branch offices around the world. We have local offices in over 10 countries & regions including the U.S, Canada, UAE, South Africa, Thailand, Vietnam, Chile, Peru, Belgium, etc. with experienced traders. With the help of these local experts, the language & cultural barrier can be minimized to zero.
2. A Strong Supply Network of Manufacturers
This is a must for any business that requires a consistent supply of quality steel.
There are countless manufacturers out there, making endless types and grades of steels for various applications. However, it doesn't happen often when a supplier can integrate all these manufacturers' resources and provide an all-in-one package readily available for you.
For example, take a look at the 50 top steel-producing companies according to Worldsteel. CUMIC has long-term cooperation with 9 out of the 10 top steel mills in the world. In addition, our supply network expands to over 200 mills worldwide, including many exclusive agreements with leading manufacturers.
In addition, as an extremely versatile material, steel serves different functions in countless industries, and every steel using scenario may have its own specific demand for the material. Sometimes, standardized production and processing might not be enough for your business, and that's when customization comes in handy. Apart from exclusive agreements with top quality mills, we can also customize orders tailored to your needs, and help you get just the right type of material needed.
3. Technical Support and Market Intelligence
A mediocre steel supplier provides the basic: a steel grade that meets a minimum standard. A great steel supplier is way more than that. Although there are many reputable suppliers in the marketplace, few can offer technical advice or even application knowledge for the challenges many manufacturers face today.
What you should look for instead, is more than just a supplier, because you'll find life incredibly easier when your supplier can consult with you to address downstream operations and final application performance. A trusted steel supplier is prepared to have in-depth discussions with you to provide various suggestions and help you make the right decision for materials and technical services, rather than suggest the easiest or cheapest option.

4. Demonstration in Consistent Quality
A commitment to quality and continuous improvement is an essential quality you should be looking for in a partnership. Your steel supplier should demonstrate a commitment to providing you with consistent, quality products that exceed your expectations. It's easier said than done, so look for their credentials to make sure they're legit.
For example, they should maintain a quality management system in conformance with their ISO : certification (view our certification here)
Information pertaining to customer experiences (like a customer feedback report, or the type of past projects they have participated in should be readily available.
CUMIC's commitment to quality is also based on how we handle quality control:
In fact, over 55% of our orders have undergone strict inspection by globally known inspection organizations such as SGS, Bureau Veritas Group, and Intertek, with who we also signed a strategic alliance.
Over third-party inspection reports are provided per year.
We closely supervise the production process of mills with sampling inspection.
5. Long-term Strategies
Anyone that works in raw material sourcing knows, it takes A LOT of work to select a new supplier, and it's even more of a nuisance to switch steel suppliers.
For the procurement of industrial goods, consistency is key, so look for a steel supplier that has a clear long-term strategy.
You want a steel supplier who thinks big and commits to providing long-term solutions, rather than someone who's in the business for some quick cash without consistency.
When it comes to long-term strategies, you can check out your prospective supplier's company history to see how they've evolved, and also see their visions & missions to get a taste of their company culture as well as strategic plans.
More than a Supplier: Look for an All-in-one steel solution provider.
A great steel supplier has the ability to provide a complete solution to the problem and work with you to identify the manufacturing challenges you have. These suppliers not only provide quality products, but also aid you in the manufacturing process and can help you to select the right material for the job.
