Hot rolling is rolling above the recrystallization temperature, contrary to cold rolling which is rolling below the recrystallization temperature. To put it simply, hot rolling is a process in which the steel billet is subjected to several rounds of rolling after ...

What is Quenching? Why Steel Needs to be Quenched?

Quenching is a heat treatment process that involves heating steel to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hyper-eutectoid steel), preserving the heat for a period of time to allow for complete or partial ...

Material for Salt-Making Evaporation Tank ...

The refined salt vacuum tank method is a fine salt production technology. By applying the principle of vacuum depression vaporization, inject the purified brine into the vacuum tank and then send the steam to the outer layer of the tank. The multi-effect ...

LEADS: What is Grade 317L Stainless Steel

317L (00Cr19Ni13Mo3, UNS S31726) alloy is a molybdenum-based austenitic stainless steel. With L behind the number, 317L is a low carbon grade. It has stronger resistance to chemical corrosion than conventional chromium-nickel austenitic ...

Stainless Steel for Vehicle Exhaust Systems

The application of stainless steel materials in automobiles began with veneering materials for decoration but has recently extended to the exhaust systems. In order to purify the exhaust gas discharged from automobiles and reduce the fuel cost by ...
