What is material nm450 steel elongation equivalent

NM450 steel elongation, Wear resistant steel plate has been widely used in the field of heavy industry, which provides important wear-resistant protection measures for the wear failure of industrial equipment and workpiece, greatly improves the service life of equipment and workpiece, and makes an important contribution to improving production efficiency and reducing production cost. A lot of equipment will be used in the processing of wear-resistant steel plate, including welding machine.

Flame cutting uses the high temperature generated during the combustion of iron oxide to cut carbon steel NM450 steel elongation. The design of the flame cutting torch provides sufficient oxygen for burning iron oxide to ensure a good cutting effect. The CNC flame cutting machine is a mechanical equipment mainly suitable for the cutting of medium and thick plates. Compared with other similar thermal cutting methods, the CNC flame cutting machine has the characteristics of high cutting quality, good cutting surface perpendicularity, and large cutting thickness.

Medium thick steel plate refers to the steel plate with a thickness of not less than 3 mm but less than 20 mm. It can be produced by reversible hot rolling medium and heavy plate mill, and its thin products can also be processed by cold rolling mill. NM450 steel elongation, Medium thick steel plates are mainly used in boilers, shipbuilding, railway cars, automobiles, containers, military industry, national defense, construction, bridges and containers.

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of NM450 steel elongation etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in NM450 steel elongation etc. steel is strictly controlled.
