Hot rolled mild steel S690QL young's modulus 2.5 mm thick

Our company's S690QL young's modulus power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the S690QL young's modulus utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.

SM490B steel, S690QL young's modulus is a kind of low carbon welded structural steel. With this low carbon equivalent, it can produce good cold forming properties. SM490B steel plate is usually supplied in hot rolling or controlled rolling delivery conditions. The SM490B is commonly used in the engineering and construction industries. It has high yield and tensile strength, and provides a variety of processing and testing options to make it highly available in your construction projects.

A516 Gr65 steel is a carbon steel plate for medium and low temperature pressure vessels, which implements the ASTM A516 standard. A516 Gr65 plate has the following characteristics: good impact resistance, small temperature deformation, good welding performance, good fatigue resistance, good anti-layered cracking performance, micro-alloying, high purity, low carbon equivalent, strong resistance to sulfur and hydrogen. Our S690QL young's modulus pressure vessel plate has good dimensional tolerance and surface quality.

Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the S690QL young's modulus steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.

The difference between S690QL young's modulus, 10# seamless steel pipe and 20# seamless steel pipe:
1. Chemical composition
Chemical composition of 10# seamless steel pipe: C: 0.07-0.13, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.15, Ni: 0.30, Cu: 0.25. Chemical composition of 20# seamless steel pipe: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25
2. Mechanical properties
10# seamless steel pipe: tensile strength: 335 MPa, yield strength: 205 MPa, elongation: 31%. 20# seamless steel pipe: tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%.
