The company cooperates with A514 grade B quenched and tempered steel steel plants such as Maanshan Iron and Steel, Youdan, Liugang, Tangshan Iron and Steel, Xinyu, Jinan Iron and Steel, Shougang, Shagang, Rizhao, Pinggang, Xicheng, Dachang and other steel mills all year round. Alloy plate, A514 grade B quenched and tempered steel boiler plate, container plate, carbon plate, open plate, I-beam, angle steel, channel steel, H-beam, round steel, steel pipe, hot rolled coil, cold rolled galvanized and other spot stocks.
30CrMnSiA steel is a grade of alloy structural steel. The steel has high strength and poor welding performance. It is a high-strength quenched and tempered structural steel with high strength and sufficient toughness after quenching and tempering, and good hardenability. It has good workability, small processing deformation and good fatigue resistance. 30CrMnSiA steel is mostly used to manufacture various important parts with high load and high speed.
High wear resistance: fully automatic CNC stacking equipment, independent of manual A514 grade B quenched and tempered steel welding technology, produces fully qualified high-quality products. Special automatic welding technology enables the chromium content of wear-resistant layer to be controlled at more than 28%, and the A514 grade B quenched and tempered steel hardness is between 58-62, which fully ensures that our wear-resistant layer has continuous good and balanced wear resistance. The wear test in metallurgy, cement and other industries shows that the wear resistance of the wear-resistant layer of the surfacing composite A514 grade B quenched and tempered steel wear-resistant steel plate is more than 30 times that of the 16Mn plate with the same thickness.
When the steel plate containing molybdenum only is at high temperature for a long time, the carbon will aggregate into graphite and precipitate, which will worsen the performance. To eliminate this tendency, chromium is often added to the A514 grade B quenched and tempered steel, steel plate at the same time. When chromium is added to the steel plate, the heat strength, high temperature oxidation resistance and corrosion resistance can also be improved.
SPA-C steel with the thickness range is 1.2-150mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the A514 grade B quenched and tempered steel, SPA-C steel coil thickness should not exceed 25 mm. SPA-C steel’s mechanical properties is yield strength more than 325 MPa, tensile strength more than 450Mpa.
