Product Description

Alloy Steel Plate SAE4140/42CrMo/DIN1.7225

1.1.7225/SAE4140/GB42CrMo,JIS SCM440 alloy steel plate

2.Hot rolled or forged condition, annealing or harden, black or milled surface

3.Pre-heat treatment:
  Annealing : heat to 840-860°c, keep 2H, furnace cold, hardness≤217HBS
  High temperature tempering : heat to 680-700°c, air cold, hardness ≤217HBS

4.Heat treatment: 
  Normalization: heating to 840 to 880 ° C, maintenance, furnace cooling to 600 ° C, then in air. 
  Stress relieving: after rough heat to 500 ° C, maintenance raff. In oven to 400 ° C, then in air.
  Hardening: preheating from 600 to 650 ° C austenitizing 
at 840 to 880 ° C, quenching in oil. 
  Tempering: heating to 550 - 650 ° C and maintenance regime, again depending on the mechanical properties 

5. Hot rolled technology:EAF+LF+VD
    Forged technology: EAF+LF+VD+ESR+Forging +Q T + Machined surface 

6.Ultrasonic test standard: SPE1921-GR3, CLASS C/C or D/D

7.Production leadtime: 7~10 days

Applications: 
 General service industries (petroleum,food, hemical,paper,ertilizer,Fabric,aviation and nuclear)
  Fluid, gas and oil transport
  Pressure and heat transmission
  Construction and ornament
  Boiler heat exchangers

Competitive Advantage:
 Good purity and homogeneity.
 Good machinability(Roughing, grinding and drilling).
 Good dimensional stability during heat treatment.
 Excellent preparation for nitriding, both ionic and gaseous, induction hardening to increase the mechanical properties. 
 Competitive price
 Fast production leadtime 
 All the material are inspected with 3 times to meet the highly standards
