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, the production is very critical and multiple heat treatment is available.
When thickness below 0.1mm, the material is also called a 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 the China’s most advantageous manufacturer for stainless steel strip(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 Material only from POSCO

Detail Matters of stainless strip
Stainless strip is widely used in different industries including tubing, mobile phones, cars, chemical, medical, and other harsh environment industries.
Coil ID
250/300/400/508mm coil ID is available from our factory. we guarantee the coil ID can suit clients’ machinery.
Chamber Rate
Chamber Rate is a key factor affecting the welding tube process, we guarantee the chamber rate is lower than
Bur Level
Bur level is well controlled to less than 5%. However, some clients need deburring service and round edges, we can provide this service.
Bundling direction
When opening the slit strip, if people can know which direction the strip is bundled, it will be much easier to load the material.
Coil Separator
for small child coils，especial for package “eye to sky”, between each and every child coil, there must be some wooden stick to separate each child coil.
Package method
For precision strip, wooden box will be applied to protect the strip from being damaged.
For each and every batch,Original MTC will be provided to guarantee the origin.
