Professional nm400 steel equivalent sheet suppliers in China

35SiMn steel can be used to manufacture parts with medium speed and medium load under the condition of quenching and tempering. 35SiMn steel can also be used to manufacture parts with high load, small impact and vibration, and parts with large cross-section and surface hardening, such as the main shaft and hub of steam turbine, impeller and various important fasteners, transmission shaft, main shaft, mandrel, connecting rod, gear, worm and trolley shaft in general machinery. In addition, NM400 steel equivalent, 35SiMn steel can also be used to make thin-walled seamless steel pipe.

NM400 steel equivalent, low alloy high strength steel has good weldability. Welding is the most common method to construct engineering structure, so the steel used in engineering structure requires good welding performance. Low alloy high strength steel has low carbon content, low alloy element content and good plasticity, so it is not easy to produce quenching structure and crack in the weld area, and the addition of Ti, Nb, V can also inhibit the grain growth in the weld area. Therefore, most of the low alloy high strength steels have excellent welding performance and no heat treatment is required after welding.

In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This NM400 steel equivalent production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate NM400 steel equivalent size.
