SPA-C steel welding for engineering and machine structural use

The company was established in 2000, covering an area of more than 4,500 acres. It has fixed assets of 200 million yuan, and employs more than 1,200 people. It has now formed coking, sintering, white ash, pellets, ironmaking, SPA-C steel welding steelmaking, steel rolling, oxygen production, gas and waste heat The complete circular economy industrial chain including power generation, comprehensive utilization of slag, soot and dust treatment, sewage treatment and recycling, etc. It mainly produces hot-rolled steel plates and SPA-C steel welding carbon structural steels, high-quality carbon structural steels, low-alloy high-strength steels, medium and wide-band steels for cold-rolled stamping, and hot-rolled coils.

What is the difference between 20G and 20# steel grade? The difference between 20G and 20# steel is very big. The chemical elements, mechanical properties, service environment and price of 20G and 20# steel are very different. SPA-C steel welding, 20G and 20# steel can not be compared. They are not of the same grade level, and can not be replaced by each other. 20# steel is high quality carbon structural steel, 20G steel is high pressure boiler steel. SPA-C steel welding, 20# steel does not bear pressure, while the use temperature of 20G steel is 450~480℃.

42CrMo steel plate is an ultra-high strength steel plate, which is widely used in machinery manufacturing steel. The steel is suitable for manufacturing large and medium-sized plastic molds that require certain strength and toughness. 42CrMo steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering, and good low temperature impact toughness.

Alloy elements have the most significant strengthening effect on steel in quenched and tempered state. The primary purpose of adding alloying elements to steel is to improve the hardenability of steel and to ensure that martensite is easily obtained during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are finer, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, SPA-C steel welding.

SPA-C steel welding discount steel plate and sheet (size mm) supply: 10*2200*12000, 18*2000*000, 14*2000*12000, 22*2500*1000, 12*2000*11000, 16*2500*10000, 14*2000*11000, 25*2000*10000, 12*2000*12000, 14*2500*10000, 14*2000*10000, 20*2500*10000, 12*1800*10000, 16*2200*000, 14*2000*9000, 22*2200*1000, 12*1800*9000, 16*2000*10,000, 16*1800*10000, 14*1800*9000, 20*2000*10000, 22*2200*10000, 30*2500*10000.

We have a professional production team and high-quality production equipment, and we also have a great SPA-C steel welding advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the SPA-C steel welding production of high-quality steel plates, steel pipes and other products that meet customer requirements.

Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
