201/202 Stainless Steel Roll

A new type of stainless steel alloy material, with good corrosion resistance, excellent processing properties and moderate strength. Its corrosion resistance is relatively low, its strength is not as good as some high nickel stainless steels, and it has some magnetic properties. When choosing to use it, you need to consider its advantages and limitations to ensure that it is suitable for specific application scenarios.
