What is NM 500 equivalent Indian standard
NM 500 is a hardened and wear-resistant steel developed and manufactured by Swedish company SSAB. It is a bendable and weldable steel, with a nominal hardness of 500 HBW. It is intended for applications requiring a high level of abrasion and wear resistance, such as those found in construction and mining equipment, buckets and hoppers, truck bodies and frames, as well as concrete mixers and other parts subject to wear. In India, the equivalent material of NM 500 can be used for the same applications is Abrasion Resistant (AR) 500 plate, also known as En-19 plates.
AR 500 plates are abrasion resistant plates that are available in various hardness range starting from 500HB to 600 HBW. They have high strength, ductility and are weldable. These plates offer superior abrasion resistance and have excellent weldability and formability. Unlike NM 500, the Indian equivalent of NM 500, Abrasion Resistant (AR) 500 plates are generally welded with low hydrogen welding electrodes or carbon dioxide welding and are usually not preheated.
Due to its superior wear and impact resistance, AR 500 plates are used in applications such as mining equipment, transportation, earth scrappers, loader buckets, crushers, bulldozers and other wear-resistant parts. It is also used in cement plants and in industrial mills. For static and mobile constructions, hard-wearing plates are commonly used for floors, ramps, stairs and bridges. They are also used in the production of grain, sand, peat and coal.
AR 500 plates, which are the Indian equivalent of NM 500, have superior hardness and strength combined with excellent ductility and welding properties. This makes them ideal for use in a variety of industrial applications and in some of the most demanding environments. With all these properties, AR 500 can effectively replace NM 500, and provide increased resistance to wear and impact in industries such as mining, construction and industrial equipment.
