Hebei ChongSheng Special Steel Pipe Co.,Ltd.

Water quenching equipment is widely used in the heat treatment of seamless steel pipe production line, through the seamless steel water quenching, improve the hardness and wear resistance of steel.
Quenching is the small diameter seamless steel pipe heated to above the critical temperature, heat for a period of time, and then quickly into the quenching agent, so that the sudden drop in temperature to greater than the critical cooling rate rapid cooling, and get martensite Lord's unbalanced organization's heat treatment method. Quenching and tempering with different temperatures can significantly improve the toughness and fatigue strength of steel to obtain better overall mechanical properties of steel. Quenching can increase the strength and hardness of small diameter seamless steel pipe, but to reduce its plasticity. Quenching quenching commonly used in: water, oil, alkali and salt solution.
