Pipes & Tubes
Manufacturer of 202 Stainless Steel Seamless & Welded Pipes & Tubes
Grade 202 stainless steel is a type of Cr-Ni-Mn stainless with similar properties to A240/SUS 302 stainless steel. The toughness of grade 202 at low temperatures is excellent.
It is one of the most widely used precipitation hardening grades, and possesses good corrosion resistance, toughness, high harness, and strength.
The following datasheet provides an overview of grade 202 B stainless steel.
