KVA Stainless has implemented patented welding and thermal processing technologies to create seam-welded martensitic tubing. KVA Martensitic Stainless Steel (MSS) tube and pipe are low-cost, high performance substitutes for traditional carbon steel, 12Cr and 13Cr materials. KVA MSS is a fully martensitic, high toughness seam-welded pipe, offering high tensile strength, hardness and wear resistance. The pipes can be produced in standard sizes up to 36in and wall thicknesses up to 0.500in. KVA longitudinal seam-welded MSS can be produced fully hardened, fully annealed, or anywhere in between. KVA Martensitic Stainless Steel is suited for mildly corrosive, abrasive media applications such as: oil sands, slurry pipelines, and coal transport. The tubing can be produced with chromium content ranging from 11.5wt% to 16wt%.
