PVQ A387 gr 12 boiler steel plate,,PVQ A387 gr 12 boiler steel plate., Q345 steel has good comprehensive mechanical properties. Q345 steel also has acceptable low temperature performance, good plasticity and weldability. Q345 steel can be used as structures, mechanical parts, building structures and general metal structures bearing dynamic loads such as medium and low pressure vessels, oil tanks, vehicles, cranes, mining machinery, power stations and bridges. Q345 steel can be used in hot rolling or normalizing state, and can be used in various structures in cold regions below - 40 ℃.

PVQ A387 gr 12 boiler steel plate,Try to use high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.

S355JR is a European standard low alloy high strength structural steel, which is in accordance with EN10025-2. The hardness of S355JR steel is 70-80B, and the yield strength of S355JR steel is 355MPa. JR stands for quality level, equivalent to level B in China
