30CrMnSiA steel material Carbon Steel Supplier

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, 30CrMnSiA steel material, 35SiMn steel can also be used to make thin-walled seamless steel pipe.

The company covers an area of 15,000 square meters and the plant construction area is 10,000 square meters. We have introduced more than 50 sets of advanced 30CrMnSiA steel material production equipment, auxiliary equipment and testing equipment at home and abroad, more than 260 employees, more than 20 middle and senior management staff, more than 10 professional and technical personnel, annual production capacity of 100,000 tons. Main products: flat steel, 30CrMnSiA steel material steel pipe, steel plate, section steel, steel structure processing parts, etc. We also accept incoming materials and annealing processing.

Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the 30CrMnSiA steel material steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.

Although 30CrMnSiA steel material, low carbon steel has excellent plasticity, toughness and processing technology, its strength is low and its corrosion resistance is not strong enough. On the basis of ordinary low carbon steel, the low alloy structural steel with high strength, high toughness, good weldability and corrosion resistance can be obtained by adding a small amount of alloy elements and the total amount is less than 3%. Manganese is the main additive element in this kind of steel, and its content is about 1% ~ 1.6%.

The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the 30CrMnSiA steel material principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
