The way to improve dimension qualification rate of NM400 steel chemical element

The ASTM A36 I beam has moderate tensile and yield strength because of its low carbon content and no other alloying elements. A36 steel beam NM400 steel chemical element is commonly used in construction and civil engineering because of its competitive low cost and good welding, forming and processing properties. The hot-dip galvanized carbon steel beam can effectively protect the steel from the corrosion of weather and environment. The amount of zinc NM400 steel chemical element plating can be customized according to your requirements.

In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product NM400 steel chemical element structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel NM400 steel chemical element supplier in the world.

Our company has the ability to produce all kinds of steel structure parts. At the same time, we can design drawings according to the requirements of customers, and process according to the drawings. NM400 steel chemical element Heat treatment services - such as annealing, normalizing, quenching, tempering, quenching and tempering, solution treatment, etc. We can also heat treat according to customer's NM400 steel chemical element requirements.

The common delivery status of NM400 steel chemical element, SA516 Gr 70 plate is as follows: 1) SA516 Gr 70 plate quenching: the process of rapid cooling after heating to the temperature above the phase transformation point. 2) SA516 Gr 70 plate normalizing: after heating above the phase transition temperature, it is cooled normally (in air). 3) SA516 Gr 70 plate annealing: heating to above the phase transition temperature, cooling slowly. 4) SA516 Gr 70 plate tempering: after quenching, it is heated to a certain temperature (lower than the quenching temperature), kept warm, and then cooled.

The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible. At the same time, a traceable product traceability system has been established. It has always been placed at an important core position to resolve customer worries. Our steel NM400 steel chemical element products are always committed to “quality issues, life-long replacement”, which is the embodiment of our comprehensive service.
