Usually, we mainly use full hard stainless steel strip production of spring steel or applied to high hardness requirements of products. And the hardness is around 430HV. With this hardness and thickness, production is very critical and multiple heat treatment is available.

When the thickness is below 0.1mm, the material is also called stainless foil. 0.07mm stainless foil production is very hard, there are some key processes.

raw material choice
We chose only master rolls of POSCO. Other sources are available, but yields are low. Especially the thickness below 0.1mm.
3 rolling +3 annealing process
The production of stainless steel foil is very slow, if the production is too fast, the foil will break, and the cost is very high.
Only 20 rolled Senzimier machinery
And in order to produce stainless steel foil, we can only use this brand of machine.

With years of experience in stainless steel, we became one of China’s most advantageous manufacturers of stainless steel strips (stainless foil). And our steel strips are known for different strength profiles and surface characteristics.
Usually, our stainless steel strips are used for a variety of applications. Such as chemical filters, corrugated stainless steel pipes, stainless steel hoses, textile healds, and hose clamps. In addition, you can purchase a wide range of strips in standard and professional stainless steel grades. The product comes in a wide range of sizes, up to 720 mm wide and 0.07 mm thick. You can customize the stainless steel strip. We can meet your special needs.

Generally, Raw Materials are only from POSCO.
