GB/T 1591 -2018 Q355B steel,Q355 steel

GB/T 1591 -2018 Q355B steel is a new Chinese steel grade of Q345B Low Alloy High Strength Structural Steel. The material density is 7.85 g/cm3.  Q355B plates can be delivered in as rolled, normalized or normalizing rolling, thermomechanical processed condition.  According to GB/T 1591 -2018, Q355 steel has 3 quality levels: Q355B, Q355C and Q355D. “Q” is the first letter of Chinese Pinyin: “qu fu dian”, which means Yield Strength, “355” is the minimum value of yield strength 355 MPa for steel thickness ≤16mm, and tensile strength is 470-630 Mpa.

1Cr6Si2Mo heat-resistant steel

1Cr6Si2Mo steel is a martensitic heat-resistant steel with good oxidation resistance at 800℃. Compared with 1Cr5Mo steel, the Si content is 1.5% more, which makes the temper brittleness tendency of the 1Cr6Si2Mo steel increase, and the parts will produce brittle fracture when working at high temperature for a long time. The steel has good corrosion resistance in sulfur-containing oxidizing atmosphere and hot petroleum medium. Chemical Composition(%) C≤0.08 Si:1.5-2.0 Mn≤0.37 P≤0.014 S≤0.001 Cr:4.0-6.0 Mo:0.45-0.6 Ni≤0.04 Mechanical properties Yield strength: 401Mpa; Tensile strength: 547Mpa; Elongation: 31.5% After normalizing and tempering heat treatment, 1Cr6Si2Mo heat-resistant steel has higher endurance strength and creep strength. The steel has an air quenching phenomenon. After hot working, if it is cooled too quickly, cracks will occur and it should be cooled slowly. Weldability is poor, electric welding can be used, gas welding is not suitable, preheating to 300
