Features and Scope:
High strength and 15Cr steel hardenability, toughness is poor; welding is good, generally do not need heat treatment after welding. Ministry for the center and surface strength requirements to withstand high wear, large size, or shape of the load is not more complex carburizing parts such as gears, gear shafts, cam, piston pin, worm, also used as work withstand the impact of large and medium-velocity load conditioning parts.
Chemical Composition: Carbon C: 0.18 ~ 0.24 ,Si Si: 0.17 ~ 0.37 ,Manganese Mn: 0.50 ~ 0.80 ,S S: to allow the residual content ≤ 0.035 ,P P: ≤ 0.035 to allow the residual content ,Chromium Cr: 0.70 ~ 1.00
,Ni-Ni: ≤ 0.030 to allow the residual content ,Copper Cu: ≤ 0.030 to allow the residual content
Mechanical Properties:
Tensile strength σb (MPa): ≥ 835 (85)
Yield strength σs (MPa): ≥ 540 (55)
Elongation δ5 (%): ≥ 10
Reduction of area ψ (%): ≥ 40
Impact energy Akv (J): ≥ 47
Impact toughness αkv (J/cm2): ≥ 59 (6)
Hardness: ≤ 179HB
Sample size: Sample size is 15mm rough
