welding of nm400 steel sheet specifications

45MnB characteristics and applications: alloy structural steel has good hardenability, the critical hardenable diameter in oil reaches 17 ~ 31mm. The machinability of steel welding of NM400 steel sheet is good, the forging and heat treatment process performance is also good, the tendency of grain growth, oxidation, decarburization and heat treatment deformation is also small when heated. 45MnB steel is mainly used for gears on machine tools, spindles of drilling machines, turning shafts and cams of tractors.

The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable welding of NM400 steel sheet steel products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the market and has strong competitiveness.

Magnetic particle flaw detection is only suitable for detecting surface defects, which means that by laying magnetic powder on the surface of the equipment and using its aggregate shape on the surface defects of the magnetic material equipment to determine the position, size and shape of the defect. This welding of NM400 steel sheet method has a relatively low cost and is easy for steel production enterprises to adopt in batches. However, for special steel profiles with deeper thickness, whether this method is used to detect hidden defects is yet to be verified.

After adding a small amount of niobium, vanadium and titanium to welding of NM400 steel sheet etc. steel, it is combined with the controlled rolling process to control the precipitation behavior of microalloying elements to achieve the purpose of improving the comprehensive properties of the steel, whether it is strength, toughness, ductile-brittle transition temperature, or Steel's process formability, welding performance, corrosion resistance and crack resistance have been significantly improved, while reducing production costs. Such steel products are widely used in oil and gas pipelines, vehicles, building structures, oil production platforms, pressure vessels, ship shells and many other fields.

Provide special product requirements to meet the personalized needs of customers. The welding of NM400 steel sheet company arranges production and shipment strictly according to the contract, and guarantees to supply goods according to the time agreed in the contract. Provide professional consultation: we guarantee to answer any professional and welding of NM400 steel sheet technical questions raised by users within 1 hour; provide detailed information.
