Machinabilit
Stainless steel grade 420J2 is machinable both in hardened and tempered conditions such as turning, drilling, and bending; however it is recommended that machining in hardened condition should be avoided as far as possible.
Welding
Welding of stainless steel grade 420J2 is easy. It is recommended that welding in annealed or hardened and tempered conditions should be avoided as it causes formation of brittleness, resulting in cold cracking due to contraction stresses.
Pre-heating and inter-pass temperature control during welding, followed by very slow cooling and post-weld annealing are good measures to take to prevent cracking.
Annealing
Annealing of this material can be performed by heating uniformly to 840-900°C (1544-1652°F) and held until the temperature is uniform throughout the section. Soaking and cooling is required.
Heat Treatment
Stainless steel grade 420J2 has to be heated uniformly to 730-790°C (1346-1454°F) and held until temperature is uniform throughout the section.
Hardening
Stainless steel grade 420J2 can be hardened by heating 950-1020°C (1742-1868°F) and held until temperature is uniform throughout the section. This should be followed by quenching in oil or air cooling. Tempering should be done when it is slightly warm.
Applications
Stainless steel grade 420J2 is used in the following application areas:
Surgical instruments
Daggers and swords
Budget knives and diving knives
Haircutting scissors and domestic scissors

Stainless steel round steel according to the production process can be divided into hot rolling, forging and cold drawn three kinds. The specifications of the hot rolled stainless steel round bar is 5.5 to 250 mm. Among them: 5.5-25 mm small stainless steel round bar mostly to straight into a bundle of supplies, commonly used for reinforcement, bolt, and various mechanical parts; Greater than 25 mm stainless steel round steel, mainly used in the manufacture of mechanical parts and seamless steel tube billet.
