Participating tenders with clients is part of our B750L structure steel for cold forming business. Every year, we support a lot of clients to win tenders and supply steel materials to their govenment progects or state owned enterprise. Until now, we have built B750L structure steel for cold forming long-term cooperation for many govermental departments of different countries such as Peru, Bangladesh, Indonesia, Egypt, Qatar, etc.. And we have built certain influence and credibility on the International market.

With the increase of carbon content in the steel material, the yield point and tensile strength increase, but the plasticity and impact decrease. When the carbon content is more than 0.23%, the welding performance of the steel material becomes worse. Therefore, the carbon content of low alloy structural steel used for welding is generally less than 0.20%. The high carbon content can also reduce the atmospheric corrosion resistance of steel material, and the high carbon steel in the open air is easy to rust; in addition, carbon can increase the cold brittleness and aging sensitivity of B750L structure steel for cold forming etc. steel material.

According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for B750L structure steel for cold forming, 42CrMo steel is quenching and tempering.

We had a wonderful trip in Phuket Island, Thailand. At the end of 2019, in order to thank employees for their hard work for a year and enrich their lives, our company organized a pleasant trip to Phuket Island, Thailand. The tour lasted 6 days and 5 nights, and returned by plane on the evening of December 27. We took off in Zhengzhou at about 5 o'clock in the afternoon on the 22th December.
