Description
1.2357 is a chromium-vanadium alloy tool steel commonly used in various industrial applications due to its excellent toughness and wear resistance properties. It is often utilized in the production of molds, dies, and other tools that require high durability and reliability.
Applications
Chisels, rivet sets, punches, driver bolts. Hot punching and shearing.
Soft Annealing
Heat to 810-850℃, cool slowly in furnace. This will produce a maximum Brinell hardness of 229.
Stress Relieving
To relieve machining stresses for greater accuracy in hardening – first rough machine, then anneal below the critical at 649/677 ℃ a minimum of one hour at temperature and cool slowly, then finish machine.
Hardening
Harden from a temperature of 930-960℃ followed by air or oil quenching. Hardness after quenching is 59-61 HRC.
Tempering
Tempering temperature: 150-400℃.
Forging
Hot forming temperature: 1066-1121℃.
Machinability
The machinability of alloy may be rated at about 75/80 % of a 1 % carbon tool steel.
Corrosion Resistance
Corrosion resistance of this alloy is better than that of plain carbon steels. However it will rust unless given protective treatment.
