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 420J2 is known to possess good strength and reasonable impact resistant properties in hardened and tempered conditions when compared with 440 grades.
As a martensitic stainless steel that provides good corrosion resistance similar to 410 plus increased strength and hardness. It is magnetic in both the annealed and hardened conditions. Maximum corrosion resistance is attained only in the fully hardened condition. It is never used in the annealed condition.

Striping processing, commonly known as “slitting “, refers to the winding of a metal coil by unwinding, slitting, leveling, winding, and processing into a desired width. Slitting processing is a basic metal processing technology that combines high-quality equipment with skilled craftsmanship. it can be obtained with strict tolerance, perfect surface control , safe packaging as well as fine transportation.
Stainless steel grade 420J2 is used in the following application areas
Cutlery, surgical and dental instruments, tapes, straight edges, fasteners, firearms
Surgical instruments Daggers and swords Budget knives and diving knives
Haircutting scissors and domestic scissors
