Production process and application field of stainless steel forgings

Stainless steel forging is an important structural and functional part, which is widely used in many fields. This paper will introduce the production process and application field of stainless steel forgings.

Production technology

The production process of stainless steel forgings includes raw material preparation, pre-heating, forging, annealing treatment, heat treatment, surface treatment and other steps. Among them, forging is a key link in the production of stainless steel forgings, including semi-precision forging, precision forging and special forging. The specific forging process should be determined according to the material, shape and use requirements of stainless steel forgings.

Preparation of raw materials: The production of stainless steel forgings requires the use of stainless steel materials, such as stainless steel 304, 316, etc. In the raw material preparation stage, the quality inspection of the stainless steel material is required to ensure that it meets the requirements.

Pre-heating: Before forging, the stainless steel material needs to be pre-heated to soften the material and improve its plasticity. The temperature and time of pre-heating should be determined according to the material and thickness of the stainless steel material.

Forging: After pre-heating, the stainless steel material is put into the forging equipment for forging. Forgings of different shapes and sizes are produced as required.

Annealing treatment: After forging, the stainless steel forgings need to be annealed to eliminate the internal stress generated during the forging process and improve the plasticity and toughness of the material. The temperature and time of annealing treatment should be determined according to the material and thickness of stainless steel.

Heat treatment: After annealing treatment, according to the need, the stainless steel forgings are heat treated to adjust their mechanical properties and corrosion resistance. The temperature and time of heat treatment should be determined according to the material and thickness of the stainless steel material.

Surface treatment: After heat treatment, surface treatment can be carried out according to needs, such as polishing, sandblasting, electroplating, etc., to improve its beauty and corrosion resistance.

Application field
