High strength SM490B carbon steel plate sheet suppliers

The company has superior geographical location and convenient transportation. After more than 20 years of market trials and tribulations, from small to large, from weak to strong, in order to meet the needs of customer extension development, the company expanded the deep SM490B carbon steel plate sheet processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and SM490B carbon steel plate sheet steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.

The company's headquarters has a well-established logistics distribution system, which can quickly transport the steel materials to the port through the contracted logistics companies. Professional contracted logistics companies can significantly reduce costs and various commodity-related expenses. Meanwhile, the flexible transfer ensures that the SM490B carbon steel plate sheet steel materials can be shipped immediately after passing the quality inspection.

Steel production and rolling technology and equipment also pursue the continuity between processes, such as the continuous SM490B carbon steel plate sheet 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.

The Qatar Railways company launched a tender for designing ,construction and completion of Green Line Project. Our company has participated in the bidding from Qatar Railway Company since May, 2016. A delegation from project visited several famous SM490B carbon steel plate sheet pipe mill in China for 15 days in July,2016. Of course the delegations had visited our pipe mill.

40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. SM490B carbon steel plate sheet, 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 SM490B carbon steel plate sheet 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.
