The charpy impact values of nm400 equivalent material

The advantage of plasma cutting is that it can cut thin plates, stainless steel and non-ferrous metals, and the cutting speed is fast. The disadvantage of plasma cutting is that the incision will have a slope, and there will be noise when cutting. The advantages of water jet cutting are wide cutting range and environmental protection, but the disadvantages of water jet cutting are slow cutting speed and high energy consumption. Do you know what is the best cutting method for NM400 equivalent material?

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of NM400 equivalent material etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in NM400 equivalent material etc. steel is strictly controlled.

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, NM400 equivalent material. 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.

Our quality control department will do inspection for details of the steel materials NM400 equivalent material before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.
