What is 51crv4 hot rolled alloy steel bar hardness
In line with the service concept of "honesty first, customer first" and the service tenet of "all for customer satisfaction", the company adopts the acceptance and response mode of combining manual and automatic, and accepts the diversified service demands of customer business consultation, complaint declaration, business acceptance, etc. through telephone, fax, e-mail, visit, letter, etc.
High strength wear-resistant plate is a kind of plate product used for large area wear condition. It is made by overlaying a certain thickness of high hardness and excellent wear-resistant layer on the surface of ordinary low carbon steel or low alloy steel with good toughness and plasticity. After production, the high-strength wear-resistant plate will be tested for its strength and bearing pressure. High strength wear-resistant plate is very wear-resistant, in the case of no accident, the service life of 51crv4 hot rolled alloy steel bar, high-strength wear-resistant plate is very long.
40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. 51crv4 hot rolled alloy steel bar, 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
Strip steel is a kind of steel plate with thin thickness, narrow width and long length. Strip steel can be made of common carbon steel, carbon structural steel, spring steel, tool steel, stainless steel, etc. Strip steel has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. There are many kinds of strip steel, 51crv4 hot rolled alloy steel bar. Hot rolled steel strip is mainly used for cold-rolled billets, cold-formed steel billets, welded steel pipe billets, manufacture of bicycles and small hardware products.
