High temperature strength of slip on flanges

　　The specific manufacturing method is: the hot-pressing elbow is made by heating the pipe and processing with professional equipment, then cutting and heating to above the critical temperature. After holding for a period of time, the slip on flange is quickly put into the quenching agent, which makes the temperature drop abruptly. The slip on flange is made by the method of rapid cooling faster than the critical cooling speed.

　　One of the treatment methods: quenching

　　Quenching is to heat the slip on flange above the critical temperature for a period of time, and then quickly put into the quenching agent, so that 1Inch Stainless Steel 316L CL900 Slip On Flange temperature drops sharply, cooling faster than the critical cooling speed, and obtain the heat treatment method of unbalanced structure dominated by martensite. Quenching can increase the strength and hardness of steel, but slip on flange plasticity. The common quenchants used in quenching are water, oil, alkali water and salt solution.
