Tempered Stainless Steel

Tempering is compressing flat stainless steel under very high pressure between two rolls to flatten and elongate it. Temper passing increases the material surface's yield strength and tensile strength.

We supply 200, 300 and 400 series stainless steel in all tempers from annealed to full hard.
