What grade is EN 10025-6 high strength steel S550QL1?

Based on the EN 10025-6 high strength steel S550QL1 steel trade, the company mainly deals in Baosteel products: color coating, zinc plating, fingerprint resistance, cold rolling, hot rolling, pickling, electrical steel and other products, and can order the futures of the company's products on behalf of manufacturers. It has established cooperative relations with more than 2000 foreign customers. At the same time, it also operates a variety of products of related iron and steel enterprises. Annual sales of EN 10025-6 high strength steel S550QL1 steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel.

35CrMoA steel has high static strength, impact toughness and higher fatigue limit, higher hardenability than 40Cr, high creep strength and endurance strength at high temperature, long-term working temperature can reach 500℃; plasticity during cold deformation Medium, poor weldability. Alloy steel EN 10025-6 high strength steel S550QL1 is used as important structural parts that work under high loads, such as transmission parts of vehicles and engines; rotors, main shafts, heavy-load transmission shafts of steam turbine generators, and large-section parts.

Main uses of EN 10025-6 high strength steel S550QL1, special steel. First, special steel is used for bearing manufacturing. Second, the special steel is used for mold manufacturing, which can withstand high temperature very well, and has excellent repeated use performance, which makes the mold quality excellent also. Third, the special steel is used in the manufacture of spring plates, and the chassis of some cars need to use the spring plate, which has good elasticity and flexibility. Fourth, the special steel is used in the aerospace industry. Fifth, the special steel is used to manufacture hardware products such as knives and drill bits.

When the stainless steel plate is alloyed with chromium, the type of surface oxide is changed to that formed on pure chromium metal. This tightly adherent chromium rich oxide protects the surface from further oxidation. This kind of oxide layer is very thin, through which we can see the natural luster of the steel surface, so that EN 10025-6 high strength steel S550QL1, stainless steel has a unique surface.

42CrMo alloy steel EN 10025-6 high strength steel S550QL1: low temperature tempering welding performance thermal processing
The heating temperature is 1150 ~1200°C, the starting temperature is 1130 ~1180°C, the ending temperature is> 850°C, and when φ> 50mm, slow cooling. The normalizing temperature is 850~900°C, and the furnace is air cooled. High temperature tempering: Tempering temperature is 680~700°C, and it is air-cooled from the furnace.
