The JIS G3115 SPV 490 boiler plate steel prices implemetation standard
JIS G3115 SPV 490 boiler plate steel prices 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 JIS G3115 SPV 490 boiler plate steel prices 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. JIS G3115 SPV 490 boiler plate steel prices annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.
