Heat resistant steel, as the name implies, is a kind of steel with good stability used under high temperature conditions. Because of its unique function, SA588 Grade K atmospheric corrosion resistant structural steel, heat-resistant steel occupies a large market space in the steel market. Heat resistant steel has been used in many fields, such as boiler, steam turbine, power machinery, industrial furnace, aviation and petrochemical industry. Different heat-resistant steels have different heat-resistant properties.
our company offered 2950 ton A36 steel SA588 Grade K atmospheric corrosion resistant structural steel plate to Philippines customer, which was used to build water supply project. It is the government project. The procurement with their project engineer come to China to discuss this project in middle of 2016. After checking the mill, they signed the contract with us. we supply the ASTM A36 Original Mill Test Certificate Stamped.
The mechanical properties of 20MnV steel are as follows: tensile strength 785 MPa, yield strength 590 MPa, elongation after fracture 10%, reduction of area 40%, impact absorption energy 55 J. SA588 Grade K atmospheric corrosion resistant structural steel, 20MnV steel has good properties, good strength, toughness and plasticity, good hardenability and machinability. After carburizing, 20MnV steel can be directly quenched without secondary quenching to improve the core structure. The weldability of 20MnV steel is good, but there is temper brittleness at 300-360 ℃ during heat treatment.
We have our own factory, including the production and manufacturing of steel pipes, with a special SA588 Grade K atmospheric corrosion resistant structural steel steel pipe manufacturer and storage warehouse. Welcome to visit our factory, we will provide customers with high quality products that meet the requirements. And has the perfect SA588 Grade K atmospheric corrosion resistant structural steel after-sale service guarantee system, lets the customer save the worry and the labor.
