15CrMo alloy plate is a pearlite structure heat-resistant steel, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperature, and normalized ABS EH36 naval engineering steel has certain hydrogen corrosion resistance. Due to the high content of Cr, C and other alloy elements in 15CrMo alloy plate, the steel has obvious hardening tendency and poor weldability. The weight calculation formula of 15CrMo alloy plate: length × width × thickness × 0.00785 = kg / m. Delivery status of 15CrMo alloy plate: hot rolling, controlled rolling, normalizing, high temperature tempering, QT, etc.
Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional normalized ABS EH36 naval engineering steel production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of normalized ABS EH36 naval engineering steel leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.
Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized normalized ABS EH36 naval engineering steel are higher than that of annealed normalized ABS EH36 naval engineering steel, but the elimination of internal stress is not as good as annealing. The normalizing operation of normalized ABS EH36 naval engineering steel is simple, the cost is low, the productivity is high, and it is widely used in actual production.
The sulfur element (S element) comes from the ore and fuel coke of steelmaking. It is a harmful element in normalized ABS EH36 naval engineering steel etc. steel. Sulfur exists in steel in the form of iron sulfide (FeS). FeS and Fe form a low melting point (985℃) compound. The hot working temperature of steel is generally above 1150 - 1200℃, so when the steel is hot working, the premature melting of FeS compound causes the workpiece to crack, which is called "hot brittleness". It reduces ductility and toughness of steel and causes cracks during forging and rolling. Sulfur is also detrimental to welding performance and reduces corrosion resistance.
The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible. At the same time, a traceable product traceability system has been established. It has always been placed at an important core position to resolve customer worries. Our steel normalized ABS EH36 naval engineering steel products are always committed to “quality issues, life-long replacement”, which is the embodiment of our comprehensive service.
