0.127mm Stainless Steel Precision Strip

Thickness: 0.05mm-0.3mm
Width:10mm-710mm
Grade: 201/304/316L/310S/ 2205 and so on
Surface: No.1, 2B, No.4, No.6(HL), snow brushed
Standard: ASTM A240

When thickness is below 0.2mm, the material is also called stainless foil. 0.127mm stainless foil production is very hard, there are some key processes.

raw material choice
We can only choose POSCO’s master reel or other sources. But the yield is very low, especially the thickness of less than 0.1mm.
3 rolling +3 annealing processes
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
To produce stainless steel foil. We can only use machines of this brand.
