Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, ASTM A514 QT steel plate quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the ASTM A514 QT steel plate International leading steel materials supplier.
ASTM A514 QT steel plate, Wear-resistant plate is one of the most widely used wear-resistant steel materials. Because of its outstanding wear-resistant characteristics, wear-resistant plate has its own unique use. First, mining machinery and equipment. During ore processing and transportation, the ore and equipment often produce violent friction, the general steel plate can not bear friction for a long time, it is easy to be damaged, and wear-resistant plate is very effective to solve this problem. Second, the ground laying. Some construction site roads are paved with wear-resistant plates, for long-term use of truck transportation.
40Cr steel belongs to alloy structural steel. ASTM A514 QT steel plate, 40Cr steel has good comprehensive properties, low temperature impact toughness and low notch sensitivity after quenching and tempering on the basis of high-quality carbon structural steel No. 40. 40Cr steel mechanical properties: tensile strength: ≥ 980mpa, yield strength: ≥ 785MPa, elongation after fracture: ≥ 9%, elongation after fracture: ≥ 45%, impact absorption energy: ≥ 47J. 40Cr steel chemical composition: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.80-1.10.
The microstructure of the quenched and tempered alloy steel, ASTM A514 QT steel plate after conventional heat treatment is tempered sorbite For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite The surface hardness can reach 55HRC-58HRC After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC If the cross-section size is large but not quenched, the properties will be significantly reduced
