15Mo3 heat resistant steel plate for boiler and pressure vessel executive standard: DIN1715515Mo3 heat resistant steel plate delivery status: normally delivered in normalized status. According to the special agreement at the time of ordering, 15Mo3 heat resistant steel plate also be delivered in non processed status.15Mo3 heat resistant steel plate is mainly used for steam boiler equipment, EN10111 DD1 steel for cold forming automobile, pressure vessels, large pressure pipes, drum manufacturing of utility boilers and similar components.

Weather-resistant steel plate has excellent hot-rolled steel plate with resistance to sulfuric acid dew point corrosion. Its superior sulfuric acid dew point corrosion resistance and very high cost performance are the best materials EN10111 DD1 steel for cold forming automobile that can completely replace stainless steel and surpass stainless steel (in terms of sulfuric acid dew point corrosion resistance). ND steel has great economic significance and is in line with today's high efficiency, long life and energy saving.

Hydrogen (H) is the most harmful element in general steel such as EN10111 DD1 steel for cold forming automobile. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.

S355J2 steel plate belongs to European standard low alloy steel, the executive standard is EN10025-2. Delivery status: normalizing, hot rolling or control rolling. S355J2 corresponds to the Chinese Q345D, but the executive standard is different, the chemical composition is slightly different, but their mechanical properties are the same. S355J2 low alloy steel plate tensile strength (MPA): 450-680, impact value: - 20 ℃: ≥ 27J. EN10111 DD1 steel for cold forming automobile, S355J2 low alloy steel plate is widely used in bridges, vehicles, ships, buildings, steel structures, etc.
