Liam Pipes and Tubes is a well-respected manufacturer and supplier of Stainless Steel 420 Tubing based in Houston, USA. We provide high-strength, corrosion-resistant tubing solutions tailored for a variety of industrial applications. Stainless Steel 420 is a martensitic stainless steel celebrated for its impressive hardness, wear resistance, and decent corrosion resistance after undergoing heat treatment. At Liam Pipes and Tubes, we take pride in producing 420 tubing that adheres to rigorous quality standards, ensuring it delivers durability, precise dimensions, and dependable performance. Our 420 tubing finds its way into numerous sectors, including automotive, aerospace, medical, and manufacturing, where strength and surface finish are vital for success.
Stainless Steel 420 Tubing consists of Chromium (12–14%), Carbon (0.15–0.40%), along with trace amounts of Manganese, Silicon, Phosphorus, and Sulfur. This martensitic alloy achieves remarkable hardness and strength post-heat treatment. Its mechanical properties boast a tensile strength ranging from 700 to 850 MPa, a yield strength of about 345 MPa, and an elongation of roughly 15%. When fully hardened, it can reach hardness levels of up to 50 HRC. While its corrosion resistance is moderate, it performs admirably in mild environments, making it a great choice for wear-resistant and mechanically demanding applications.
