The production process of Best Price of sus 402 stainless steel round bar

Best Price of sus 402 stainless steel round bar is a very common craft product, which needs to go through many complicated steps in the production process to complete its forming operation. The specific production process includes pipe cutting, pickling and oil removal, inspection and grinding, cold rolling, annealing, straightening, and lubrication.

1. Pipe cutting

When producing Best Price of sus 402 stainless steel round bar, it is necessary to cut off the head and tail, including the flat ends of the two ends of the waste pipe, the cutting of intermediate products and the final cutting of finished products. Scrap of stainless steel rods is generated when cutting stainless steel rods.

2. Pickling to remove oil

The iron oxide scale produced by the surface of the Best Price of sus 402 stainless steel round bar due to high temperature heating is removed, so as to meet the requirements of producing stainless steel bars and finished products. The engineering acid is mixed acid (HNO3+HF).

3. Inspection and grinding

Check and repair the defects of the stainless steel bars, and remove the unfavorable defects, so as to ensure the quality of the finished products later.

4. Cold rolling

The Best Price of sus 402 stainless steel round bar is subjected to deformation cold rolling operation to make it meet the required specifications. The production of stainless steel bars of different specifications requires multiple passes of cold rolling back and forth.

5. Annealing

The stainless steel bar is cold rolled to produce metal work hardening. In order to eliminate work hardening and facilitate reprocessing, annealing is required to restore the broken grains. At the same time, it also guarantees the mechanical properties of the finished stainless steel bars.

6. Straightening

The annealed stainless steel rod is bent due to thermal deformation. In order to achieve the factory straightness standard of the stainless steel rod, the stainless steel rod needs to be straightened.

7. Lubrication

Best Price of sus 402 stainless steel round bar Before cold rolling, in order to avoid direct friction between the stainless steel bar metal and the drawing die metal during the deformation process, the inner and outer surfaces of the stainless steel bar are coated with a layer of high-temperature nanogrease+ Lime-based lubricants are dried to form a barrier.
