Stainless steel coils are widely used in industrial applications, like manufacturing automotive parts, medical equipment, and kitchen appliances. If you plan to buy a stainless-steel coil, you should be ready to research.
That is partly because a few dealers need to guarantee quality in their product offerings. It's no big surprise that you want to equip yourself with first-hand information before pursuing this purchase choice. Here's what you ought to know.
Before deciding on anything, consider your reason for investing in a stainless steel coil. Different grades of stainless steel are ideal for different applications. For instance, 304 stainless steel is a general-purpose grade suitable for most applications.
Things are different with 316 stainless steel since it is commonly used in marine environments thanks to its higher resistance to corrosion. In short, determine your application before shopping for the best stainless-steel coil to leverage.
You probably already know that stainless-steel coils come in different thicknesses, measured in gauge. The thickness you settle on depends on your requirement for a stainless-steel coil. If it involves the coil for automotive parts, you should use a thicker gauge for sturdiness.
It is additionally essential that you factor in the width and length. The size of the stainless-steel coil you want depends on your application. Continuously measure the area where you will utilize the coil to get the right size for your requirements.
Only some of the odd stainless steel coil suppliers are worth your attention. Some are just in it for the business and care less about product quality. That is the reason the choice of supplier is essential while pursuing this purchase choice. Search for a supplier with a good reputation for quality and customer service.
It generally pays off to ask for references and read online reviews to ensure you're dealing with a reliable supplier. Before paying for their products, try to find as much information as possible about the stainless-steel coil supplier.
Remember that the prices of stainless-steel coils tend to shift depending on the grade, finish, thickness, width, and length. Ensure you compare prices from different suppliers to get a fair price on your purchase.
As long as the quality is good enough, stainless steel is one of the safest materials.
But remember, the quality matters.
So, how do you know if the stainless steel coil you&#;ve got is good or not? Try out the below methods.
The theory of the &#;magnet test&#; is a rumour.
It tells you that you can test the quality of stainless steel with a magnet.
But the fact is that the magnet is to test whether the steel is austenitic, or whether the steel contains chromium and nickel.
There are three main types of structures in stainless steel: austenite, ferrite, and martensite.
When you see stainless steel with 18/8 or 18/10 marks, it tells you the amount of chromium and nickel.
So, both 18/8 and 18/10 are austenitic.

The &#;magnet test&#; is useful when you use it in the right way. And it&#;s easy to do by simply taking a magnet to your stainless steel coil.
If the magnet sticks, the coil is safe because it indicates no nickel in the steel. But if the magnet doesn&#;t stick, it means the steel contains nickel, so the coil is not safe for food usage.
This test is credible.
If a magnet is to stick to steel, it is not a nickel (austenitic) alloy.
There is a problem with this theory, however.
First of all, there are no stainless steel pans with magnetic inside and outside. It&#;s very difficult to find a fully magnetic stainless steel coil on the market.
That&#;s not surprising. The reason is that austenitic stainless steel which contains nickel is highly resistant to corrosion.
Corrosion resistance is very important to buy stainless steel coil, isn&#;t it?
If the coil is fully magnetic stainless steel, it would corrode and not last very long. Without nickel, the metal is not stable.
For this reason, it&#;s not necessary to buy stainless steel coils that are magnetic, nickel-free.
You will find magnetic stainless steel in the outer layer of some quality stainless steel.
It&#;s to make the coil compatible with induction stovetops in case you need it for cookware. The reason is, induction stovetops use an electromagnetic field to heat the cookware.
So, high-quality stainless steel cookware usually has three layers of metal. The interior is austenite stainless steel. The exterior is ferrite stainless steel. And the middle layer is aluminium.
It&#;s for good heat conductivity because steel itself does not conduct heat evenly. Stainless steel of poor quality usually has only one austenitic layer.
But there is still a difference in quality between different types of austenitic stainless steel.
Sometimes you will find that austenitic stainless steel is less magnetic. That&#;s because, during manufacturing, the steel is cold-processed to form ferrite and martensite.
This process makes it easier to corrode and leach.
The formulation of austenitic stainless steel cookware is careful to avoid this. And the result is a very stable austenitic alloy that resists corrosion and leaching of the metal.
So, A carefully-formed, highly-stable, non-corrosive, and nickel-containing stainless steel is safer than a pure magnetic stainless steel.
Pure magnetic stainless steel will break down and corrode over time. And it doesn&#;t even exist in the market!
To be honest, it&#;s hard to know whether your stainless steel is of the best quality unless you are a metal expert. Or unless you go to the factory and see how it&#;s made. Otherwise, you won&#;t know whether your stainless steel has corrosive materials.
Your best choice is to buy high-quality stainless steel from the start, choose a brand with a good reputation for quality, such as WJH premium stainless steel.
But still, there&#;s another way for you to determine whether the stainless steel coils you&#;ve got is potentially harmful.
What is all this stuff? They are the types/grades of stainless steel. No worries. We&#;ll tell you in detail in the following section after this.
Now let&#;s focus on how to make use of the tester.
