The surface hardens to the point of being shocking. Wear-resistant materials that are difficult to adhere to magnets are supplied as processed products.
In replacement parts such as liners and screens, performance that withstands impact and wear is required. Furthermore, non-magnetic properties are necessary for equipment that wants to avoid the influence of magnetic fields. High manganese steel NM-13MN is a suitable material for non-magnetic components subjected to impact loads and wear. NM-13MN has work-hardening properties that harden the surface due to impact, exhibiting high toughness and resistance to impact wear. It is used in liners and screens for shot blasting equipment, crushers, and magnetic separation equipment. On the other hand, it is prone to hardening during cutting, making it difficult to process, so selecting not only the material but also the processing location is important. Kumagai Special Steel provides consistent support from cutting to machining, bending, and welding.

basic information
- Looking for a liner material that can achieve both non-magnetic properties and wear resistance. - Want to replace components with ones that are less likely to crack under impact and are also resistant to wear. - Want to procure NM-13MN, which is difficult to process, in a state close to finished parts. Material: NM-13MN. Plate thickness 4.5 to 25 mm, standard size 1524×3048 mm. We support the sale of standard and cut products as well as additional processing. Since its corrosion resistance is not as high as stainless steel, please consider rust prevention measures according to the usage environment. This is an impact-resistant and wear-resistant steel characterized by high manganese content. Its main feature is that the surface work hardens during use, improving wear resistance. It has high toughness, is less likely to crack, and is suitable for applications where magnetic influence should be avoided as a non-magnetic steel. 1. Main specifications and characteristics - Representative material: NM-13Mn - Characteristics: High wear resistance due to work hardening - Toughness: Very high and impact-resistant - Magnetism: Non-magnetic 2. Features of processing and construction - Requires consideration of processing conditions due to high toughness - Compatible with gas and laser cutting - Welding, bending, and canning processing are possible - Selecting processing methods according to application is important 3. Performance points - Wear resistance improves under impact load - Less likely to crack and has a long lifespan - Improved maintainability due to reduced replacement frequency
