Stainless Steel Rectangle Bar S30V is a high-alloy, martensitic stainless steel bar stock made from S30V steel - a powder metallurgy tool steel containing high amounts of vanadium, chromium, and carbon for exceptional wear resistance, toughness, and corrosion resistance. Its superior properties make it suitable for manufacturing cutting tools, knives, bearings, shafts, and other industrial components that require high hardness, edge retention, and durability under harsh operating conditions.
