Alloy steel plate is a kind of high strength steel plate, which has good wear resistance. It is suitable for road laying, factory floor and other fields with high wear resistance requirements. The performance of the 34CrMoS4 chemical composition, alloy steel plate is more prominent. The alloy steel plate has good high temperature resistance and low temperature resistance, which will not cause material deformation in any high temperature and low temperature environment. The strength retention of alloy steel plate is better, and the material stability is better.
40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. 34CrMoS4 chemical composition, 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
Both parties shall confirm the 34CrMoS4 chemical composition material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the 34CrMoS4 chemical composition steel plant.
