Our Stainless Steel

specification: Welded pipes: OD6-2032, wall thickness: 1-50mm.
certificate: ISO 9001: 2000 certify by BV, PED &AD certify by TUV.

Purpose
(1) reduce the hardness and improve the cutting process.
(2) elimination of residual stresses, stable dimensions, reduced deformation

316/316L stainless steel advantages:
Because there has Mo in it,so the corrosion resistance is very especially the pitting resistance.
