420 stainless steel is a medium-carbon stainless steel composed of chromium, carbon and molybdenum, with good corrosion resistance and strength.
202 stainless steel is made of a stainless steel with low nickel content and high manganese content. Because it is a stainless steel originally developed to save nickel, so its nickel content is lower than most other stainless steels.
301 stainless steel is a common austenitic stainless steel accommodating 17 percent chromium and 7 percent nickel, giving it extra strength and ductility when cold worked. What is more, it has amazing corrosion resistance properties.
430 stainless steel has always been a popular material for a variety of applications for its durability and corrosion resistance. However, welding 430 stainless steel can be challenging due to its high chromium content.
