Solid Solution and Precipitation Hardening Treatment of Stainless Steel Casting

The main purpose of solution treatment is to dissolve carbides or other precipitated phases in solid solution to obtain a supersaturated single-phase structure. Castings of austenitic stainless steel, austenitic manganese steel and pre...

Tempering Treatment of Steel Casting Products

Tempering refers to a heat treatment process in which the quenched or normalized steel castings are heated to a selected temperature lower than the critical point Ac1, and after holding for a period of time, they are cooled at an a...

Quenching Treatment of Steel Casting

Quenching is a heat treatment process in which steel castings are heated to a temperature above Ac3 or Ac1, and then rapidly cooled after holding for a period of time to obtain a complete martensitic structure. The steel castings ...

Normalizing Heat Treatment and Its Influence on Steel Casting Products

Normalizing is a heat treatment in which the steel is heated to 30 °C - 50 °C above Ac3 (hypoeutectoid steel) and Acm (hypereutectoid steel), and after a period of heat preservation, it is cooled to room temperature in air or i...

Annealing Treatment and Its Influence on Metal Castings

Annealing is to heat the steel whose structure deviates from the equilibrium state to a certain temperature predetermined by the process, and then slowly cool it after heat preservation (usually cooling with the furnace or burying i...

General Introduction of Heat Treatment
