The significance of developing S890QL steel equivalent

After quenching and tempering, the 40Cr alloy steel plate has good comprehensive mechanical properties, good low-temperature impact toughness and low notch sensitivity. The hardenability of steel is good. It can be hardened to Ф28～60mm in water quenching and Ф15～40mm in oil quenching. In addition to quenching and tempering, 40cr sheet is also suitable for cyanidation and high-frequency quenching.

Different form S890QL steel equivalent, room temperature and medium temperature boiler steel shall have those advantages:Higher room temperature strength;Good impact toughness and low notch sensitivity;As the drum and other parts require a lot of cold deformation during processing, room temperature and medium temperature boiler steel must have good aging toughness;Good processing technology and welding performance;Good macrostructure, etc.

In order to easily and economically perform hot or cold processing to make various parts of engineering structures, the low alloy high strength steel must have appropriate forming properties. Like S890QL steel equivalent, carbon structural steel, low alloy high strength steel can generally be processed in such way, as well as cutting, punching, and machining. Although the yield point of low alloy high strength steel is high, even if the forming operation is deformed quite severely, cold bending presses, drawing machines, presses and other equipment used for carbon structural steel forming can also be used for low alloy high strength steel, but some equipment needs to be modified.

Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled S890QL steel equivalent plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive S890QL steel equivalent industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.
