KVA Martensitic Stainless Steel Tube & Pipe

KVA Martensitic Stainless Steel (MSS) tube and pipe are low-cost, high performance substitutes for traditional carbon & stainless steels, titanium and 12Cr & 13Cr materials. KVA MSS™ is the patented, original and only fully martensitic, high toughness seam-welded tube, offering unsurpassed tensile strength, hardness and wear resistance.

KVA longitudinal seam-welded MSS™ can be produced fully hardened, fully annealed, or anywhere in between, at substantial cost savings over seamless type 410 or type 420 pipe! Typical properties of KVA MSS (UNS S41000):

KVA Martensitic Stainless Steel tubing is proudly Made in the U.S.A. and is produced in our state-of-the-art tubemaking facility in southern California. The following charts list our current size range capabilities:

Addtional sizes can be run at our partner mills ranging from 0.200" to 36" (5 - 914 mm) outside diameter and wall thicknesses from 0.008" to 0.500" (0.2 - 12.7 mm); subsquent drawing can be done to obtain any OD/wall and shape required. KVA can also process other corrosion resistant martensitic, precipation-hardening (PH) or difficult to weld grades as needed. Please contact us for details.

KVA MSS™ can be produced in lengths up to 40' or coiled to the following specifications:

• ASTM A268: Standard Specification for Seamless and Welded Ferritic and Martensitic Stainless Steel Tubing for General Service
• ASTM A554: Standard Specification for Welded Stainless Steel Mechanical Tubing
• ASTM A999: Standard Specification for General Requirements for Alloy and Stainless Steel Pipe
