June 22, 2010 - PRLog -- All the Benefits of Seamless Tubing – At a Far Lower Cost

Recognizing the need for low-cost, high strength structural tubing, KVA Stainless founder, Ed McCrink, and his development staff have implemented patented welding and thermal processing technologies to create seam-welded martensitic tubing, which took 4 years to develop and perfect.

Until recently, welding of Martensitic Stainless steel into tubing has been impossible because it will cold-crack in the heat-affected zone under mechanical straining and forming.  For this reason, Martensitic Stainless has long been considered the most difficult of the five types of Stainless to weld.

KVA Stainless has invented and developed a cost-effective, patented weld processing technology that eliminates the difficulties associated with welding Martensitic Stainless steel and results in a product that is up to 17% stronger,50% lighter, and less expensive than its alternatives.

Key advantages of KVA STAINLESS weld processing technology:
•   Improved ductility
•   Enhanced toughness
•   Elimination of cracking
•   In-line processing
•   Enabling of high-speed welding of high-carbon alloys
•   Compatible with all welding methods (GTAW, GMAW, plasma, laser, HF, resistance…)

KVA STAINLESS technology can benefit any market segment where component weight, strength and corrosion resistance are critical issues, providing a superior alternative to conventional materials.

Ideal applications include:
•   Automotive components and structures
•   Aviation components and structures
•   Gas and oil production pipelines
•   Petrochemical and process piping
•   Agricultural equipment
•   Earth-moving equipment
•   Train/rail cars and equipment
•   Heat-exchangers
•   Medical devices and wheelchairs
•   Action sporting goods – golf, baseball, bicycles

KVA Stainless seam-welded tubing can replace seamless Martensitic and expensive Austenitic Stainless steel tubing, exotic titanium alloy tubing or specialty ultra high strength steel tubes (welded or seamless).   KVA’s processed Martensitic tubing exhibits a more uniform weld metal microstructure than conventionally-processed seam-welded tubing.  After a simple air quench and temper heat-treatment, the heat-affected zone (HAZ) transforms into the same microstructure as the base metal, now exceeding strengths of 200 ksi.  

“KVA Stainless has taken its patented seam welded stainless steel tubes and manufactured several automotive parts for a few of the major automotive manufacturers.  We have also produced bicycle and wheelchair frames,” according to KVA’s vice-president of sales, Douglas Gore.  

“With this technology, high strength structural items can now be created using Martensitic Stainless steel and used in a variety of applications, with significant performance and cost benefits.  Several of our other patents and trade secret technologies allow us to produce stamped automotive parts with weight savings up to 50% while increasing overall strength by 17% of the given part,” says Gore.

Those parts include suspension components, from control arms to sub-frames, chassis frame rails, and vehicle accessories such as tow hooks and running boards.
