alloy 34CrMo4 and 51CrV4 steel and a36 plate specification
Our after sales department is an very important part of our department structures. After the customer receive steel materials, our after sales department will follow up regularly and solve problems for them in time if they have the needs. We romise to return the goods for free for its lifetime if it is quality of the steel material itself. Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.
Steel production and rolling technology and equipment also pursue the continuity between processes, such as the continuous alloy 34CrMo4 and 51CrV4 steel process between continuous casting and rolling mills, continuous casting slabs hot transfer hot charging, increased direct rolling, and continuous cold rolling processes. The development of controlled rolling and controlled cooling technology that combines rolling and heat treatment has played a huge role in improving the properties of rolled materials.
40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. alloy 34CrMo4 and 51CrV4 steel, 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
The company attaches great importance to the value of iron and steel, constantly improving itself in terms of attitude, innovation, human resources, etc., integrating the value of iron and steel into the company's philosophy, showing the spirit of fighting for alloy 34CrMo4 and 51CrV4 steel iron and steel, forging iron and steel enterprise, creating steel market, establishing iron and steel team, and attaching importance to the sustainable development of iron and steel industry, so as to make iron and steel our permanent cause.
