1000 pieces usage of NM400 steel plate delivered to Germany

The company has an entrepreneurial team composed of highly educated and high-quality talents, whose leaders graduated from famous universities. As the first group of teams engaged in e-commerce industry in China, it witnessed the rapid development of e-commerce, accumulated rich steel professional knowledge and formed a scientific management system.

Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This usage of NM400 steel plate alloy steel usage of NM400 steel plate still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.

TMCP process is an indispensable technology for our production of low alloy high strength wide and usage of NM400 steel plate thick steel plates. TMCP process can produce steel with high strength and toughness without adding too many alloy elements and complex subsequent heat treatment. TMCP is a process that can save alloy usage of NM400 steel plate and energy and is beneficial to environmental protection. A lot of our shipbuilding steel plates are produced by TMCP process.

On March 17 th 2018, our Sudan customer purchased the SG295 cylinder steel coils through other country such as UAE,Turkey before they cooperate with us. After they research our regular customer in Uganda, UAE, and his friends in China, he is satisfied with our company. Our produced SG295 cylinder steel is mainly used to fabricate low temperature pressure vessels like gas cylinder. The customer is very satisfied to our usage of NM400 steel plate quality control and professional arrangement for the SG295 steel order.
