ASTM A268 standard 446 stainless steel tubing, 446 stainless steel coil price

Short Description:

Stainless steels are known as high-alloy steels. They have excellent corrosion resistance in comparison with other steels as they contain more chromium.
Based on their crystalline structure, stainless steels are divided into three groups, namely, martensitic, austenitic and ferritic steels. A combination of martensitic and ferritic steels forms a fourth group known as precipitation-hardened steels.
The grade 446 stainless steel is a ferritic, non-heat treatable stainless steel that provides good resistance to high temperature oxidation and corrosion. The following datasheet provides more details of grade 446 stainless steel.
