"Patented Weld Processing Technology Creates a More Uniform Weld Metal Microstructure"

KVA Martensitic Stainless Steel tubes and pipes are low-cost, high performance substitutes for traditional carbon steel, 12Cr and 13Cr materials. KVA martensitic stainless steel pipe technology is the patented, original and only fully martensitic, high toughness seam-welded pipe, offering unsurpassed tensile strength, hardness and wear resistance as compared to common low carbon corrosion resistant modifications such as:

• Duracorr™ (UNS S41003)
• Cromgard™ (UNS S41003)
• 3Cr12
• 410S (UNS S41008)
• 409 (UNS S40920)
• 12Cr
• 13Cr

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:

Hardened:
Yield strength: 160 ksi (1100 MPa)
Ultimate tensile strength: 205 ksi (1400 MPa)
Hardness: 370-390 Brinell (40-42C Rockwell )
Elongation: 8-9%

Annealed:
Yield strength: 45 ksi (300 MPa)
Ultimate tensile strength: 80 ksi (530 MPa)
Hardness: 130 Brinell (80B Rockwell )
Elongation: 30+%

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:

• Oil sands
• Slurry pipelines
• Coal transport

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:

• ASTM A268: Standard Specification for Seamless and Welded Ferritic and Martensitic Stainless Steel Tubing for General Service
• ASTM A999: Standard Specification for General Requirements for Alloy and Stainless Steel Pipe
• API-5LC: Specification for CRA Line Pipe

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.
