What is the S960QL steel?

S960QL steel has a yield strength of 590Mpa - 960MPa, and is widely used in the manufacture of mine car floor above 100 tons, pumping machinery, excavators, truck cranes, crawler cranes, coal mine hydraulic supports, etc.

Application: quenched and tempered high-strength steel for construction machinery
The production specification of quenched and tempered steel: S960QL plates thickness 8 ~ 150mm, width 1500 ~ 4000mm, length 3000 ~ 16000mm. Good welding performance: welding test results show that the welding seam and fusion line -40 ℃ V-type impact is greater than 60J.

Advantages of S960QL high strength steel

Strict tolerances ensure excellent consistency of steel plate performance
High impact toughness ensures good crack resistance
Excellent bendability and surface quality
Excellent weldability, excellent HAZ strength and toughness

S960QL steel has high strength, especially in normalized or normalized and tempered state with high comprehensive mechanical properties. S960QL high strength steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, locomotives, cranes, mining machinery and other large welded structural parts.
Done is better than perfect.

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
