carbon content of NM400 per kg price

The sensitivity of high temperature tempering brittleness of wear-resistant plates is generally expressed by the difference between the toughness and brittleness transition temperature of the toughened state and the embrittlement state. The more serious the brittleness of high temperature tempering, the higher the proportion of the fracture surface along the grain of the wear-resistant steel plate, carbon content of NM400. The effect of the elements in the wear plate on the high temperature temper brittleness is divided into two aspects. One is the impurity elements that cause the high temperature temper brittleness of the wear plate.

Sulfur is a very harmful element in carbon content of NM400 steel. The presence of sulfur will increase the hot brittleness of steel, reduce the various mechanical properties of carbon content of NM400 steel, and reduce the weldability, impact toughness, fatigue resistance and corrosion resistance of steel.

There is a careful, patient, enthusiastic and thoughtful after-sales team, a professional distribution, ultra-efficient warehouse and logistics center, a marketing team with marketing expertise, an innovative technology center with strong steel technology, an experienced manufacturing center with rigorous professionalism Quality Inspection Center, an operation team with many years of administrative management experience. Such a strong combination of teams makes BEBON a steel giant in Henan Province.

The company has strict control on the quality of carbon content of NM400. Each carbon content of NM400 is inspected for the whole process, including raw material purchase, production process according to the procedures and relevant regulations. According to the technical standards and technical requirements, the composite quality inspection is carried out to confirm whether the carbon content of NM400 meets the specified quality requirements.
