KVA Martensitic Stainless Steel pipes can be produced in standard sizes up to 36" and wall thicknesses up to 0.500". Non-standard sizes upon request.
KVA longitudinal seam-welded martensitic stainless steel can be produced fully hardened, fully annealed, or anywhere in between, at substantial cost savings over seamless 410 or 420 pipe! Typical properties of KVA martensitic stainless steel pipe:
Yield strength: 160 ksi (1100 MPa)
Ultimate tensile strength: 205 ksi (1400 MPa)
Hardness: 370-390 Brinell (40-42C Rockwell )
Yield strength: 45 ksi (300 MPa)
Ultimate tensile strength: 80 ksi (530 MPa)
Hardness: 130 Brinell (80B Rockwell )
The introduction of KVA Martensitic Stainless Steel for the transport, oil and gas pipelines is ideally suited for mildly corrosive, abrasive media applications such as:
The abrasion resistance of hardened KVA martensitic stainless steel tube and pipe is unmatched – maximizing durability, reliability and reducing erosion-corrosion failures. KVA Martensitic stainless steel tubing and pipe can be produced with chromium content ranging from 11.5wt% to 16wt%, maximizing production and service life while minimizing cost.
KVA martensitic stainless steel can be produced to the following specifications:
Please contact us to discuss your particular application for KVA martensitic stainless steel technology. KVA STAINLESS™ can recommend the appropriate welding procedure for field welding martensitic stainless steel without cracking or embrittlement for welding methods such as:
Gas Tungsten Arc Welding (GTAW/TIG), Gas Metal Arc Welding (GMAW/MIG), Shielded Metal Arc Welding (SMAW/"stick"), Submerged Arc Welding (SAW), Electric Resistance Welding (ERW) and Laser/Hybrid Laser-Assist Welding.
