Liam Pipes and Tubes is a well-respected manufacturer and supplier of Stainless Steel 420 Pipes based in Houston, USA. We specialize in providing high-strength and wear-resistant piping solutions that cater to a variety of industrial needs. Stainless Steel 420 is a martensitic stainless steel celebrated for its impressive hardness, corrosion resistance, and ability to take a polish. Our 420 pipes are crafted with precision and adhere to international quality standards, making them perfect for even the toughest environments. With our dedication to excellence, competitive pricing, and prompt delivery, Liam Pipes and Tubes has become a trusted partner for durable and reliable stainless steel piping products.
Stainless Steel 420 Pipes are made up of Chromium (12–14%), Carbon (0.15–0.40%), along with trace amounts of Manganese, Silicon, and Sulfur. As a hardenable martensitic grade, 420 boasts high strength and remarkable wear resistance after undergoing heat treatment. Its mechanical properties include a tensile strength ranging from 700 to 850 MPa, a yield strength of about 345 MPa, and an elongation of roughly 15%. When hardened, these pipes can reach a hardness of up to 50 HRC, ensuring durability in mechanical and tooling applications where moderate corrosion resistance and hardness are essential.

Stainless Steel 420 Pipes find their place in applications that demand high hardness, strength, and moderate corrosion resistance. You’ll often see them in the production of surgical and dental instruments, cutting tools, valves, shafts, and pump components. The alloy’s ability to be polished and retain edges also makes it a great choice for knife blades, molds, and dies. In the industrial realm, 420 pipes are utilized in mechanical parts that face abrasion and friction. Thanks to their resistance to mild chemicals and oxidizing environments, they are also used in food processing, paper mills, and petroleum applications that require toughness and wear resistance.
