It is a modern high-tech professional enterprise integrating scientific research, production and sales.

The steel plate used for containers and pressure vessel has to bear different pressures and strengths due to the manufactured containers. The normal pressure is generally 31.4MPa or higher; the working temperature is usually between -20 ℃ -450 ℃, and sometimes lower than -20 ℃. According to the working conditions and processing technology of the container, the SM400B carbon steel plate sheet, steel plate used for the container must have good cold bending and welding performance. Besides, it should have good plasticity and toughness, high temperature short-term strength or long-term strength performance.

42CrMo steel plate is an ultra-high strength steel plate, which is widely used in machinery manufacturing steel. The steel is suitable for manufacturing large and medium-sized plastic molds that require certain strength and toughness. 42CrMo steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering, and good low temperature impact toughness.

Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while SM400B carbon steel plate sheet steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of SM400B carbon steel plate sheet steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.

SM400B carbon steel plate sheet, No.45 seamless pipe belongs to high quality carbon structural steel. The carbon (C) content of No.45 seamless pipe is 0.42 ~ 0.50%, Si content is 0.17 ~ 0.37%, Mn content is 0.50 ~ 0.80%, Cr content is ≤ 0.25%, Ni content is ≤ 0.30%, Cu content is ≤ 0.25%. The tensile strength, yield strength, elongation, reduction of area and impact energy of No.45 seamless pipe are 600 MPa, 355 MPa, 16% and 40% respectively. No.45 seamless pipe is used to manufacture high strength moving parts.

The company's after-sales service tenet is "customer first, timely guarantee, enthusiastic service and effective work". In order to establish a set of perfect after-sales service system and strict management system, so that the after-sales service can be effectively guaranteed. The company has set up after-sales service department to ensure timely, unique and effective response to every user's request, coordinate internal resources internally, and put an end to all evasion and delay.
