Hild strength low alloy impact resistance of nm400 steel plate price list

Since the foundation of the company, the Spring Festival Gala is an annual activity held at the end of the year. Now it is a part of the BBN company culture to enrich the employee's life. The annual Spring Festival Gala in 2019 was held on January 20, 2020. There are opening ceremony, leader's speech, BBN steel performance, awards for outstanding employees, lucky draw, party game, curtain call, company group photo, annual Gala dinner and other links.

How to predict the price trend of medium and heavy plate, impact resistance of NM400 steel plate? First, the output of steel plate. The future annual plan of the major steel mills can be learned timely through the official website. Second, market demand forecast. Third, overall data of the global steel, judgment and rectification of foreign political trade, such as tariff. Of course, we should also consider the transportation cost and other factors, which will also affect the price of medium and heavy plate, impact resistance of NM400 steel plate.

40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. impact resistance of NM400 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

The mechanical properties of 30CrMo steel are as follows: tensile strength 930 MPa, yield strength 785 MPa, elongation after fracture 12%, impact absorption energy 63 J. impact resistance of NM400 steel plate, 30CrMo steel has high strength and toughness. When the temperature is lower than 500℃, 30CrMo steel has good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance. 30CrMo steel is generally used in quenched and tempered condition.
