Do you need equivalent grades of nm450 steel stock

15MnNi steel plate is used for nuclear safety second and third grade pressure vessel steel. Since nuclear power equipment is used in harsh environments such as high temperature, high pressure and neutron radiation all year round, the steel equivalent grades of NM450 steel for equipment manufacturing is required to have suitable strength, high toughness, and low brittle transition temperature. The characteristics of strong performance and anti-radiation ability and low alloy element content, so there are strict requirements in room temperature stretching, high temperature stretching, thickness direction stretching and hardness.

As a leading hot rolled plate mill in China, We manufacture and export carbon steel and alloy equivalent grades of NM450 steel steel plates in different sizes and of different thickness. We have an adept and proficient team of professionals in addition to our responsive staff that is ever alert for any customer queries and requisites. If you are experiencing difficulty in selecting the correct equivalent grades of NM450 steel steel plates for your business, we have a team of experts who can give you the best advice on steel plates, a significant contributor that can flourish your business.

Quenching Improve the hardness of equivalent grades of NM450 steel steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of equivalent grades of NM450 steel steel and comprehensive mechanical properties.

The allowable temperature of equivalent grades of NM450 steel, boiler steel is mainly determined by strength condition. Different steels have different mechanical properties and high temperature properties. Even for the same kind of steel, the tensile strength, yield strength and rupture strength vary greatly with the working temperature, and decrease with the increase of working temperature. In order to ensure the safety of equivalent grades of NM450 steel work, the actual stress of equivalent grades of NM450 steel under the working temperature should be less than the allowable stress determined by the tensile strength, yield limit and permanent strength of equivalent grades of NM450 steel under the temperature.

We guarantee to provide all technical data required by users within one hour to provide reasonable quotation; to provide equivalent grades of NM450 steel reasonable quotation for products consulted by users within one hour; to provide investigation reception: we guarantee to receive the investigation of users at any time and provide various convenient conditions for users.
