Bright annealed stainless steel pipe
Product classification:309/309S,310/310S,etc.
The price of this series of stainless steel is relatively low, and it is generally used for civilian products. Generally in the hot chloride environment should be selected. In kitchen products, household appliances, decoration, automotive exhaust systems, petrochemical and other civil and industrial fields can partially replace 300 series austenitic stainless steel.

Product details

Stainless steel bright annealing refers to the process of heating and cooling at a certain temperature on the surface and inside of stainless steel to achieve certain mechanical properties and surface quality requirements.

Through this annealing treatment, the crystal structure and chemical composition of stainless steel can be changed, so that it has better physical and chemical properties. Specifically, the role of stainless steel bright annealing includes: improve the strength and wear resistance of stainless steel materials; Improve the surface quality of stainless steel, so that it has better corrosion resistance; Eliminate the internal stress of stainless steel material, improve its processing performance; The structure of the stainless steel material is homogenized, and the deformation and cracks of the stainless steel material are reduced.
