The Complete Guide to Buying Stainless Steel Coil

Home / Blog /The Complete Guide to Buying Stainless Steel Coil

A lot of people find it quite challenging to purchase stainless steel coils. It is to be mentioned that there are more than 60 grades of stainless steel. This is a complete guide to helping people choose the best stainless steel coil. Let us start.

Different Factors You Need Consider

1. Corrosion resistance

This topic of corrosion resistance is extremely important to know when purchasing stainless steel products. The standard grade most commonly used for food grade applications is AUSTENITIC STAINLESS STEEL. Due to its chemistry, austenitic stainless steels show tremendous resistance to basic corrosive environments containing only salt and water. Specifically, our 304 – grades (including but not limited to), include 18/22, 20/30, 15/25, and 10/15. Use the proper grade based on your installation environs; atmospheric conditions such as air quality, moisture content, and acidity levels can greatly increase the corrosion rate of a product.

2. Resistance to heat

Many More customers choose stainless steel coils because they can use them everywhere without any concern about the corrosion. Temperature is a factor to consider when purchasing stainless steel products. High temperatures, such as in a furnace environment of (900 – 1175C) can increase the corrosion of stainless steel products. Moreover, high temperature exerts high pressure on the products. So you will have to purchase heat-resistant stainless steel, such as 253MA and 321MA if the temperature is always high.

3. Cryogenic resistance

Austenitic stainless steel is more efficient at low temperatures. They can maintain a higher tensile strength at low temperatures compared to ambient temperatures. Regardless of degrading and toughness, such steel is suitable for low temperatures. Cryogenic resistance means that the materials ability to withstand decreased material temperature after exposure to increasing pressures. You must check cryogenic resistance to know which one is better for you.

4. Magnetic response

Austenitic and ferritic grades of stainless steel typically have a lower magnetic content, whereas chromium-based grades are more magnetically active. You must check the magnetic response for each type of grade; austenitic is not as strong as carbonitride and 310, 316, and 430 grade steels so these all tend to show very little effect. Martensitic Stainless with higher magnetic content such as 310, 320, 330, 410, and 416 , which are not magnetic but can be made into hardware that is by using posthardening processes such as nitriding, has deep cryogenic Tempering to achieve those characteristics. Duplex grades like 2205 and 2201 are ferromagnetic while others like 400CN and 452CBM are paramagnetic.

5. Cost

Cost is one of the most important factors when buying stainless steel coil. Stainless steel of high price can be worth the money as it can run for a longer time. So you need to access the costs depending upon the basis of the life cycle. Different 201 stainless steel coil sell the products at different costs.

6. Strength required

It can be quite complex to know the steel strength that you require. The strength requirement depends upon the installation environment and the purpose of installation. In some cases, high-strength duplex and austenitic stainless steel are suitable. But in some cases, these can be the most unsuitable as they cannot meet your requirements. So you must check the strength that is required for your work.

7. Common manufacturers

The stainless steel coils are available from a number of manufacturers in the world. Foshan Poscc Steel Co.,Ltd is a professional manufacturer with more than 20 years of experience in manufacturing stainless steel, carbon steel, and galvanized steel established in 2001. We also offer stainless steel coils of these brands including POSCC, TISCO, ZPSS, Baosteel, POSCO, LISCO, YUSCO, Ansteel, QPSS, JISCO, HXSCO, Chengde, Yongjin, Tsingshan, Shouyang, HW, etc.

Different Types You Need Consider

301 stainless steel

With high ductile, 301 steel is most used for molding products. It can harden rapidly during machining. As to the abrasive resistance and fatigue strength, 301 steel is better than 304 steel.

302 stainless steel

Its corrosion resistance is the same as 304, but the strength is slightly higher due to the addition of carbon.

303 stainless steel

By adding the elements of sulfur and phosphorus, 303 stainless steel is easier to process when compared to 304 steel. ISO 3506 named it “A1”

304 stainless steel

304 stainless steel is the most common 18/8 stainless steel. It has also known name “A2” by ISO3506.

316 stainless steel

316/316L sheet possesses excellent mechanical properties at sub-zero temperatures and good corrosion resistance making it a great choice for marine applications.
