Supply chemical composition of nm400 for hull structure

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 , 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.

, 27SiMn material has high strength and wear resistance, high hardenability, medium plasticity during cold deformation, good machinability and fair weldability. It is mostly used after quenching and tempering, and can also be used in normalizing or hot rolling state. 27SiMn material chemical elements: C: 0.24-0.32, Si: 1.10-1.40, Mn: 1.10-1.40. 27SiMn material mechanical properties: tensile strength 980 MPa; yield strength: 835 MPa; elongation after fracture: 12%; impact energy: 39J. 27SiMn material can be used to make hot stamping parts with high toughness and high wear resistance, which do not need heat treatment or normalizing, such as tractor track pins.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc We are provided best packing for structural steel plates to avoid rust Our after-sales service team will contact you if you have any question,chemical composition of NM400.

Our pipeline steel has once again helped the construction of the China-Russia East Line Natural Gas Pipeline. During 2017 - 2018, the company successively supplied more than 10,000 tons of high-grade pipeline steel materials for the northern section of the Sino-Russian Eastern Gas Pipeline project, helping the northern section of the project to be successfully completed. Now we reload the task and will provide API 5L X80 high-grade pipeline steel for the middle section of the China-Russia Eastern Gas Pipeline project.
