Hot rolled mechanical properties of nm300 steel sheet specification

Abrasion resistant steel mechanical properties of nm300 steel which is also known as (AR steel) wear resistant steel, is developed to have longer service life than mild steel. Abrasion resistant steel is widely used in underground mines, cement industry, road construction, mining and open-pit mining and metallurgical industries and manufacturing other wear-resistant parts.

The basic principle of mechanical properties of nm300 steel, 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.

Steel is an alloy of iron with carbon, silicon, manganese, phosphorus, sulfur and a small amount of other elements. In addition to iron, carbon content plays an important role in the mechanical properties of mechanical properties of nm300 steel and so on steel. Iron and steel is an important raw material for machinery, construction, hardware and other industries. As an important pillar industry, the development of iron and steel has a glorious period, in which Tangshan was once an important production base of China's iron and steel. This is closely related to its geographical location and energy advantages.

The mechanical properties of nm300 steel steel making furnace can only be used as primary refining, and the refining needs to be completed in the refining equipment outside the furnace, which is also called secondary refining. It is mainly through decarburization, desulfuration, denitrification and dephosphorization to improve the cleanness of the steel, to establish a chromium molybdenum low alloy steel with good oxidation resistance and high temperature strength, to remove unwanted harmful impurities from the steel, and to improve the mechanical properties of nm300 steel internal quality of the steel.
