How to quickly judge whether the price of A514 Gr Q high strength steel plate, weathering steel plate is reasonable? What are the factors influencing the price quotation of A514 Gr Q high strength steel plate, weathering steel plate? First of all, the material composition of weathering steel plate is different, and the corresponding performance and price are also different. Therefore, when we talk about the price of A514 Gr Q high strength steel plate, weathering steel plate, we should first make clear of the material composition. Secondly, the specification especially the thickness of the A514 Gr Q high strength steel plate, weathering steel plate will affect the quotation. Generally, the thicker the weathering steel plate, the higher the price.
Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the A514 Gr Q high strength steel plate steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the A514 Gr Q high strength steel plate weathering steel is purified and the content of inclusions is greatly reduced.
40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. A514 Gr Q high strength steel plate, 40Cr alloy chemical composition (C: 0.37 ~ 0.44, Si: 0.17 ~ 0.37, Mn: 0.50 ~ 0.80, Cr: 0.80 ~ 1.10, Ni: ≤0.30, P: ≤0.030, S: ≤0.030, Cu: ≤0.30, Mo: ≤0.10). Heat treatment: First quenching heating temperature (℃): 850; coolant: oil; Temperature heating temperature (℃): 520. 40Cr steel tensile strength (σb / MPa): ≥980. Yield point (σs / MPa): ≥785
