What is carbon content of NM400 material

S35C steel is a high-quality carbon structural steel, which has good plasticity and appropriate strength, good process performance, and acceptable welding performance. It is mostly used in normalized and quenched and tempered states. Grades included in the JIS G 4051 standard: S10C, S15C, S20C, S25C, S30C, S33C, S35C, S40C, carbon content of NM400, S45C, S48C, S50C, S53C, S55C, S58C, S09CK, S15CK, S20CK.

The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating carbon content of NM400 production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the carbon content of NM400 quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After carbon content of NM400 quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.

Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. It has the characteristics of high-quality steel such as toughness, plastic extension, forming, welding and cutting, abrasion, high temperature and fatigue. carbon content of NM400, Weathering steel sheets are used to manufacture containers, railway vehicles, oil derricks, harbour buildings, oil production platforms and containers containing hydrogen sulfide corrosive media in chemical oil equipment.

Both parties shall confirm the carbon content of NM400 material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the carbon content of NM400 steel plant.
