A2 STEEL/ PLASTIC MOULD STEEL/ AIR-HARDENING, MEDIUM-ALLOY, COLD-WORK STEELS:
A2 STEEL/ PLASTIC MOULD STEEL
A2 Tool Steel Plate utilized in thermosetting plastic molds and typical hardened molds. A2 is American excessive-durability wear-resistant device metallic, belonging to wind-hardened metallic. Steels of the type A2, A3, A4, A6, A7, A8, A9, and A10 form air-hardening, medium alloy, cold work steels or group A steels.
AISI A2 Tool Steel is an air-hardening grade of metal that includes 5% chromium. A2 is cited for its good longevity and exceptional dimensional balance in heat treatment. These characteristics make it a flexible device steel that combines proper performance and charge.
Characteristics of A2 plastic mould steel:
Low alloyed Presipitation hardening metallic, with suitable complete mechanical homes, excessive hardenability, handy heat treatment, small deformation after heat treatment, good polishability. This cloth additionally has excellent nitriding, electric machining, welding, and sample marking performation.
