What is en NM400 equivalent steel material
En NM400 is a high alloy, wear-resistant steel grade produced in Germany by the S+H Metallurgical Group, part of Schmolz + Bickenbach. The material is an austenitic martensitic and ferritic chromium-cobalt-molybdenum alloyed stainless steel that provides excellent wear resistance, strength and corrosion protection. The material was originally developed for roller bit drill crushers, buckets and blades found in the mining industry, and is now being used to improve the performance of other industrial components and machine parts.
En NM400 is a high alloy steel, specially designed for operation under extreme wear and harsh conditions. It has an excellent strength-to-weight ratio and a high wear resistance, which makes it suitable for a variety of applications. Its high wear resistance comes from its chromium, cobalt and molybdenum alloying elements, which form a protective carbide layer on the surface of the steel, preventing any deformation, deterioration, cracks and other damage caused by friction and wear.
The main alloying elements in En NM400 are chromium and molybdenum, which are both typical alloying elements found in stainless steels. Chromium is added to increase the corrosion resistance of the steel, and the molybdenum adds hardness, toughness and wear resistance. The chromium and molybdenum combination also enhances the resistance to corrosion, corrosion fatigue and abrasion. The high alloy composition of En NM400 helps to achieve excellent wear-resistance properties due to its mechanical hardening mechanism.
Due to its superior wear-resistance and fatigue-resistance, EN NM400 is often used in drilling, mining, construction and other industries in which wear is a major factor. It is also used in agricultural, automotive and marine applications. En NM400 can be used in a variety of applications such as wear plates, roller bearing components, screws, nuts, wear strips, bushings, cutting tools, gears and industrial machine components.
En NM400 is an equivalent material to the stainless steel DIN 1.4034, a martensitic stainless steel that can also be used as an alternative to En NM400 in various applications. The DIN 1.4034 material is a low-alloy stainless steel designed for the same wear-resistant properties as the En NM400. DIN 1.4034 also contains between 11.5% and 13% chromium, between 0.6% and 1.2% molybdenum and between 0.6% and 1.2% carbon. This low-alloy stainless steel is typically used in applications that require corrosion resistance and high hardness, such as drill bits, knives and other tools.
In comparison to other tool steels, En NM400 is a higher alloy stainless steel with a higher strength-to-weight ratio and superior resistance to wear and abrasion. This makes it the ideal material for a variety of applications in the drilling, mining, construction and automotive industries. The combination of chromium, molybdenum and cobalt help to improve the wear-resistance, strength and corrosion protection of the material, making it a highly desirable material for industrial application.
