1.7220/35CrMo/SAE4135/SCM435 Mechanical Alloy Tool Steel
Chemical Component(%)
ASTM 4135 has high fatigue limit of static strength, impact toughness and high hardenability, higher
than 40Cr, has high creep strength and rupture strength under high temperature, long-term working temperature of 500 degree; cold plastic deformation medium, poor weldability.
Application:
SAE 4135 Alloy Steel used for vehicles, engines and machines-axles, turbine components, chains, Forgings, Truck, turbine or rotor drive shafts, gearbox gears, axles, half-shafts for rear axle stays.Shafts of All types, gears and any components subject to fatigue stresses.
Hot rolled technology:EAF+LF+VD
Forged technology:EAF+LF+VD+ESR+Forging+Q T+Machined surface
Heat treatment:
Annealing or Q+T
Surface treatment:
Black/Peeling/Polishing/machined
Package:
We provide standard export packing or according to customers' request.
Delivery time:
