The operation situation of 16mo3 steel density in the first three quarters

Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of 16Mo3 steel density, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.

Hydrogen (H) is the most harmful element in general steel such as 16mo3 steel density. 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.

16mo3 steel density, SA387Gr11CL2 CrMo alloy steel plate has the properties of preventing hydrogen embrittlement, hydrogen corrosion, hydrogen stripping and sulfide corrosion in the medium temperature (350 - 480℃) hydrogen environment, and has good low temper embrittlement. 16mo3 steel density, SA387Gr11CL2 is widely used in the manufacture of chemical fertilizer, petrochemical industry and thermal power plant equipment, such as synthetic ammonia reactor, coal gasifier, shift converter and hydrogenation reactor.
