1/8 equivalent grades of nm450 steel 4x8 factory near me

16MnD5 is a medium carbon quenched and tempered steel with good strength, toughness and hardenability. It can obtain better comprehensive mechanical properties after quenching and tempering. After quality, it has higher fatigue strength and resistance to multiple impacts. Low temperature impact toughness Good, no obvious temper brittleness. equivalent grades of NM450 steel product is mainly used to make evaporators, voltage stabilizers, pressure vessels and heads, supporting members, etc. in nuclear power projects

The company adheres to green development, supported by scientific and technological innovation and technological progress, vigorously advocates the equivalent grades of NM450 steel production and life style of saving, environmental protection, civilization and low carbon, adheres to the new industrialization road and the sustainable development road. Actively carry out international trade and maintain stable economic and trade relations with more than 80 countries and regions including the United States, Germany, France, the United Kingdom, Japan, South Korea and Australia.

Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the equivalent grades of NM450 steel steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.

The acicular ferrite pipeline steel can inhibit the formation of polygonal ferrite, promote the acicular ferrite transformation, and improve the precipitation strengthening effect of carbon and niobium nitride by adding molybdenum to reduce the transformation temperature of polygonal ferrite, so as to improve the strength of steel and reduce the ductile brittle transition temperature. The equivalent grades of NM450 steel, tempered sorbite pipeline steel adopts the heat treatment process of quenching and tempering. The tempered sorbite structure is formed to meet the comprehensive requirements of thick wall, high strength and sufficient toughness.
