How about 1Cr5Mo heat-resistant steel properties

Heat-resistant steel can resist the corrosion produced in the process of petroleum cracking. 1Cr5Mo heat-resistant steel is used for reheating steam pipes, petroleum cracking pipes, piston rods, boiler hangers, cylinder liners, pump parts, high-pressure hydrogenation equipment parts, fasteners, etc.

Chemical composition of 1Cr5Mo heat-resistant steel:
Carbon C: ≤0.15
Silicon Si: ≤0.50
Phosphorus P: ≤0.030
Chromium Cr: 4.00~6.00
Nickel Ni: ≤0.60
Manganese Mn: ≤0.60
Sulfur S: ≤0.020

Mechanical properties of 1Cr5Mo heat-resistant steel:
Yield strength of 1Cr5Mo heat-resistant steel σ0.2 (MPa): ≥185
Tensile strength of 1Cr5Mo heat-resistant steel: δbMPa≥390
Elongation rate of 1Cr5Mo heat-resistant steel δ5%: ≥22
Hardness of 1Cr5Mo heat-resistant steel: ≤187HB

Heat treatment process of 1Cr5Mo heat-resistant steel:
1. Quenching, 900-950℃ oil cooling;
2. Tempering, air cooling at 600-700℃.
