En-31 cold work tool steel
En-31 cold work tool steel
Specification
EN31 Steel Rod is a actual high strength steel alloy which is tough and hardened before contributing and has nickel, chromium, molybdenum making it great tensile steel power, with decent ductility and uniform resistance. EN31 is an actual great strength alloy manufacturing steel. EN31 mechanical properties is a superiority high carbon alloy steel which propositions a high degree of rigidity with compressive power and scrape resistance.
Application
EN31 round bars are fundamentally used as a Connector between the pipes at the middle. They are also used as a socket in to struggle pressure in Pressure Regulators. EN31 steel bar have chromium and is heat preserved for making products like front automobile axles, Obverse Axle beam, axle periodicals, crankshafts, steering components. EN31 Alloy Steel Bar are basically used as a Connector between the pipes at the middle whereas EN31 steel bar are average carbon and chromium steel, with decent ductile strength.
