Louis Metals is a trusted Stainless Steel 420 Round Bars and Rods manufacturer and supplier in Houston, USA, offering quality stainless steel solutions to various industries. Precision engineering, strength, and reliability are what Louis Metals is renowned for. Louis Metals produces SS 420 round bars according to stern international quality standards. With superior quality raw materials and latest manufacturing techniques, Louis Metals produces SS 420 round bars of superior hardness and corrosion resistance. Heat treatable, Stainless Steel 420 round bars and rods are most suitable for applications where wear resistance, strength, and dimensional stability are of utmost concern, such as in tools, machinery, and medical devices.
Stainless Steel 420 Round Bars and Rods are martensitic stainless steels containing 12–14% Chromium, 0.15–0.40% Carbon, and traces of Manganese, Silicon, Phosphorus, and Sulfur. SS 420, when heat-treated, possesses high tensile strength of 700–900 MPa and yield strength of about 500 MPa with hardness of up to 50 HRC. SS 420 possesses moderate ductility and is magnetic in hardened and annealed conditions. SS 420 possesses good corrosion resistance in mild conditions and high wear and abrasion resistance, and hence they are suitable for components subjected to mechanical stress and require higher service life.

Stainless Steel 420 Round Bars and Rods are widely used in applications that demand strength, wear resistance, and mild corrosion resistance. They are employed in the manufacture of surgical and dental tools, cutlery, pump shafts, valve parts, molds, dies, and gear components. The bars are appropriately employed in fasteners for automobiles and industrial machines, tools, and machine parts. In oil and gas, SS 420 is utilized in downhole tools and fittings. Its appropriateness for heat-treating for hardening and polishing to a fine surface makes it a very popular material for functional and cosmetic applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
