Welcome to BBN High Strength Steels Factory
Q355NH material is a Chinese steel grade to GB/T 4171-2008 atmospheric corrosion resisting structural steel. There are five steel levels under Q355NH: Grade A, B, C, D, and E. Q355NH structural steel sheet is mainly used in vehicles, containers, construction, towers or other structural parts and other structures. It has good resistance to atmospheric corrosion. We supply S500 steel, Q355NH steel plates thickness less than 120mm.
Pickled steel coils are processed by pickling machines to remove the oxide layer. Because of the deoxidation treatment, certain characteristics of the pickled steel coils are more prominent. First, the surface is smoother and exquisite. For products that require the appearance of the steel plates, pickling steel coil is a good choice. Second, the surface of the pickled steel coil is smooth and not easy to oxidize, and it is convenient and quick to paint. Third, S500 steel, pickled steel coils have high precision.
S500 steel annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of S500 steel annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. S500 steel annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.
