BBN supply nm400 material cold bending performance

The definition of wear of NM400 wear resistant plate, NM400 material: the definition of wear in German standard: due to the contact and relative motion between solid and its matching solid, liquid or gas, the mechanical action is produced on the solid, resulting in material loss on the surface. The American Society for Testing and Materials (ASTM) standard defines abrasion: a solid surface damage caused by the relative motion between an object's surface and a contact material.

Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled NM400 material products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the NM400 material rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.

Strip steel is mainly divided into hot-rolled ordinary strip steel, cold-rolled ordinary strip steel, hot-rolled high-quality strip steel and cold-rolled high-quality strip steel. The NM400 material, hot-rolled carbon strip steel is made of ordinary carbon structural steel, and is hot-rolled into strip steel with a thickness of 1.80-6.00mm and a width of 50-1200mm. The hot-rolled carbon strip steel is mainly used for the manufacture of cold-rolled billets, cold-formed steel billets, welded steel pipe billets, bicycles, and small hardware products.

The basic principle of NM400 material, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.
