Company Overview and Vision
KVA STAINLESS, based in southern California, is a prominent US manufacturer and supplier of stainless steel and high alloy welded tubing. The company operates as a growing R&D venture, dedicated to developing and promoting the use of lightweight, ultra high-strength, and cost-effective stainless steel alloys. Founded by Mr. Ed McCrink in 1953, KVA continues his vision of leveraging martensitic stainless steels to enhance structural strength while reducing weight across various industries. The technical team, with extensive experience in thermal processing, metallurgy, automated welding, brazing, and mechanical design, has pioneered numerous proprietary and patent-pending methods. KVA's mission is to deliver innovative, low-cost, advanced high-strength martensitic stainless steel processing technology and solutions to its industrial clientele, emphasizing first-rate research, high-quality manufacturing, and customer service.
Advanced Materials and Technologies
KVA STAINLESS specializes in martensitic stainless steel (MSS) and other high-strength alloys. A key offering is MS3 bike tubing, a precipitation hardening martensitic stainless steel boasting over 200 ksi (1400 Mpa) tensile strength, which is noted as being twice as strong as titanium with a frame weight comparable to high-end aluminum. The company's patented welding and thermal processing techniques are central to its capabilities. KVA's heat treatment technology employs simple air-quench processes, ensuring uniform properties throughout parts with minimal distortion and enabling continuous or batch processing. This allows complex geometries to be formed in a soft, annealed state with low-cost tooling, then hardened effectively. Their weld processing technology overcomes conventional limitations of high-speed welding air-hardenable MSS, eliminating issues like cold-cracking and enabling ductile, tough weldments that achieve uniform microstructures after heat treatment, performing comparably to seamless joints.
Product Offerings and Applications
KVA produces stainless, nickel, and titanium alloy tubing, with capabilities ranging from 0.500' to 3.000' diameter and 0.016' to 0.125' wall thickness. Products adhere to standards such as ASTM A249, A268, and ASME SA 249. The company's technology is applied across diverse markets, including aerospace, automotive, energy, medical device, chemical, and food processing. Specific applications include lightweight and high-strength automotive chassis components (e.g., intrusion management and body-in-white structures), transport gas and oil pipelines, and structural elements for scaffolding, bridges, and high-rise buildings. KVA also develops advanced martensitic heliostats and solar trackers, providing superior alternatives where component weight, strength, longevity, and corrosion resistance are critical.
Key Advantages and Manufacturing Excellence
A significant advantage of KVA's technology is the ability to achieve 30-45% mass reduction in automotive structural applications while maintaining or exceeding strength levels. The air-hardening property of MSS, combined with KVA's proprietary processing, allows for high-strength components with minimal distortion, offering a cost-effective alternative to traditional materials. KVA MSS' is highlighted as a patented, original, fully martensitic, seam-welded tube known for unsurpassed tensile strength, hardness, and wear resistance, often at substantial cost savings over seamless alternatives. All KVA tubing is proudly manufactured in the U.S.A. at their state-of-the-art facility in southern California, reflecting a commitment to quality and innovation driven by decades of specialized experience.
