What are the main applicable ranges of chemical composition of NM450
In recent years, in line with the development trend of iron and chemical composition of NM450 steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which chemical composition of NM450 are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
High strength steel is mainly used in offshore engineering, lifting equipment, construction machinery, container storage tank and other important steel structures with harsh working conditions, hoping to reduce weight. The application of chemical composition of NM450, high strength steel can not only reduce material cost, transportation cost and production cost, but also save welding material consumption, welding work hour; reduce post welding stress, preheating temperature and post weld heat treatment requirements.
Our SA516Gr70 pressure vessel plate has good impact resistance, small temperature deformation, good welding performance, good fatigue resistance, good anti-layered cracking performance, micro-alloying, high purity, low carbon equivalent, strong resistance to sulfur and hydrogen. The product has good dimensional tolerance and surface quality. China made chemical composition of NM450 steel plates are now widely used in major chemical sites.
Fatigue wear often occurs on the rolling or rolling and sliding friction surface of the wear-resistant plate, chemical composition of NM450. Under the action of alternating stress, the soft area of the surface will produce plastic deformation. When the stress exceeds the tensile strength of the material, cracks will appear in the weak places, and the cracks will continue to expand under the effect of stress. When the crack length reaches a certain value, it will cause fracture and cause the phenomenon of pitting and spalling.
The outer diameter of the hot-rolled seamless pipe is generally larger than 32mm, and the wall thickness is 2.5-75mm. The diameter of the cold-rolled seamless pipe can be 6mm, the wall thickness can be 0.25mm, the outer diameter of the thin-walled pipe can be 5mm, and the wall thickness is less than 0.25mm. The size accuracy of the cold-rolled seamless pipe is higher than that of the hot-rolled seamless pipe, chemical composition of NM450.
The chemical composition of NM450 pressure vessel steel plates are our featured products. We have supplied pressure vessel steel plates to tank manufactures, boiler makers, power plants and so on customers all over the world. We have online service for you at any time, welcome to contact and learn more information about pressure vessel steel, such as chemical composition of NM450 ASTM A537 class 1 equivalent, 16Mo3 datasheet, Q245R material properties, Q345R material specification, P355GH properties, pressure vessel steel price, etc.
The company conducts periodic and targeted training and guidance for after-sales service personnel. As the saying goes, "no one is perfect, no gold is red", to help after-sales service personnel improve service skills and correct service attitude. Carry out relevant technical training for after-sales service personnel, so that after-sales service practitioners have professional product knowledge.
