SUS420J2 stainless steel seamless pipe is produced according to Japanese industrial standards and belongs to the 420 series stainless steel. It has high hardness, strength and wear resistance. At the same time, it has good corrosion resistance under certain conditions. A layer of oxide film is formed on the surface, which can play a certain anti-corrosion role.
In addition, SUS420J2 steel pipe has high hardness and is suitable for manufacturing knives, cutting tools and other parts that require high hardness and wear resistance.
