chemical composition of nm400 quality and thickness range

Nickel element is mainly used to form and stabilize the austenite structure, so that the chemical composition of NM400 steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.

How to distinguish the inferior steel plate? 1. The surface of the fake and inferior steel plate is easy to produce scab. 2. The material of fake and inferior steel plate is not uniform and there are many impurities. The surface of fake and inferior steel plate is often pitted. Pitting is an irregular and uneven defect on the surface of chemical composition of NM400, steel plate caused by serious wear of rolling groove. Due to the pursuit of profit by the manufacturers of fake and inferior steel plates, the groove rolling often exceeds the standard.

The hardness of chemical composition of NM400, wear-resistant steel plate is an important standard to measure wear resistance. The hardness of wear-resistant steel plate can be divided into microhardness and surface hardness. The microhardness of carbide in the wear-resistant layer of wear-resistant steel plate can reach over HVl700-2000, and the surface hardness can reach HRC58-62. Chromium alloy is the main wear-resistant layer of wear-resistant steel plate, and other alloy components such as manganese, molybdenum, niobium, nickel are added at the same time.

Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the chemical composition of NM400 project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of chemical composition of NM400 customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.
