Six characteristics and heat treatment process of stainless steel machining parts

Stainless steel machining parts are steel alloys containing at least 10% chromium. The extra chromium provides the original surface finish and excellent corrosion resistance not found in carbon steel. The processing equipment of stainless steel machining parts is classified into cutting equipment of stainless steel machining parts and surface treatment equipment of stainless steel machining parts. The cutting equipment of stainless steel machining parts is divided into equipment and slitting equipment. In addition, from the thickness of the stainless steel machining parts, there is cold and hot rolling processing equipment. Thermal cutting equipment mainly includes plasma cutting, laser cutting, water cutting, and so on. Now let me introduce the six characteristics and heat treatment process of stainless steel machining parts. Here are some answers.

Six characteristics of stainless steel machining parts.

First, the stainless steel machining parts have complete specifications and diverse materials. Second, the dimensional accuracy of stainless steel machining parts is high, up to ±0.1mm. Third, the surface quality of stainless steel machining parts is good, and the brightness is good. Fourth, stainless steel machining parts have strong corrosion resistance, high tensile strength, and fatigue resistance. Fifth, the chemical composition of stainless steel machining parts is stable, the steel is pure, and the content of inclusions is low. Sixth, the packaging of stainless steel machining parts is intact, and the price of stainless steel machining parts is favorable.    

The heat treatment process of stainless steel machining parts.

The heat treatment of stainless steel machining parts includes annealing, normalizing, quenching, tempering, and other processes. Annealing of stainless steel machining parts refers to the processing technology of heat-treating stainless steel machining parts after heating the material of the stainless steel machining parts to a certain temperature, keeping it for a certain period, and then slowly cooling. Normalizing of stainless steel machining parts refers to heat-treated stainless steel that heats the material of the stainless steel machining parts to 30-50℃ above Ac3 or Acm (the upper critical point temperature of steel), then maintains it for a certain period and then places it in still air to cool naturally. The processing technology of the workpiece. Quenching of stainless steel machining parts refers to heating the material of stainless steel machining parts to a temperature above Ac3 or Ac1 (the lower critical point the temperature of steel), maintaining it for a certain period, and then using a suitable cooling rate to obtain a martensitic structure. Processing technology of heat-treated stainless steel machining parts The tempering of stainless steel machining parts refers to the processing technology of heat treatment stainless steel machining partsafter the material of the stainless steel machining parts is quenched and then heated to a temperature below Ac1, maintained at the temperature for a certain period, and then cooled to room temperature.
