Description
Stainless Steel Grade 420J2 (UNS S42000)
Stainless Steel Grade 420J2 is inexpensive and highly corrosion resistant steel. It has good corrosion resistance in mild atmosphere as well as domestic and industrial environments. It is also resistant to dilute nitric acid, carbonic acid, ammonia, crude oil, detergent solutions, vinegar, food acids, several petroleum products, and steam.
Stainless steel grade SS 420J2 is known to possess good strength and reasonable impact resistant properties in hardened and tempered conditions when compared with 440 grades.
Stainless Steel with an even higher quenching hardness than SUS420J1
