Chemical composition (%): Silicon: 0.17~0.37
Mechanical properties: Tensile strength σb (MPa): ≥835

Yield strength σs (MPa): ≥540

Elongation δ5 (%): ≥10

Area shrinkage ψ (%): ≥40

impact absorption energy Ak (J) ≥47

hardness: annealed or high temperature tempering supply state hardness ≤156HB

sample size: sample size 15mm
Heat treatment specification and metallographic structure:
Heat treatment specification: quenching temperature (℃) 880 for the first time, 780 to 820 for the second time, coolant water and oil. Tempering temperature (℃) 200, coolant water, air.
Welding performance:
20Cr parts with thickness greater than 15mm need to be preheated to 100~150℃ before welding. If it is not required to be high, preheating may not be performed before welding, and tempering heat treatment may not be performed after welding.
