Ed Stainless is a prominent producer and exporter of Stainless Steel 420 Plates and Sheets, proudly situated in Houston, Texas, USA. Famed for accurate engineering and very high quality standards, Ed Stainless provides top-level stainless steel products for industries in Texas and other locations. With a firm focus on innovation, customer contentment, and prompt delivery, the company serves an assortment of industrial requirements such as automotive, defense, oil & gas, and construction. As a reputable stainless steel producer, Ed Stainless provides reliable, corrosion-resistant 420 grade sheet and plate products that meet both national and international standards.
Ed Stainless Texas-produced Stainless Steel 420 Sheets and Plates are martensitic stainless steels with high carbon content for hardness. They contain 12–14% chromium as a typical composition, up to 1.0% manganese, and 0.15–0.40% carbon. These plates also have good mechanical properties including 700–850 MPa tensile strength, 350 MPa yield strength, and up to 50 HRC hardness after heat treatment. Suitable for where strength and average corrosion resistance are required, 420 stainless steel does not lose much machinability and polishability, and hence it is favored for precision parts and cutting tools.

These are stainless steel 420 hot rolled sheets that can offer excellent corrosion resistance and a durability that no other material could. They range from 3mm to 12mm thickness and are most suitable for any application that calls for high strength and good machinability.
Stainless Steel 420 cold rolled plates offer excellent corrosion resistance and a bright finish. These plates are available in thicknesses ranging from 0.5mm to 6mm and are used in precision applications where dimensional accuracy and fine surface finish are critical.
Stainless Steel 420 chequered plates combine excellent corrosion resistance with a textured surface for slip resistance. They are available in thicknesses from 2mm to 8mm and various patterns, and are widely used in flooring and safety applications.
Stainless Steel 420 perforated sheets are corrosion-resistant and have uniform holes for ventilation and aesthetics. They are available in thicknesses from 1mm to 5mm and are used in filtering and architectural applications.
Stainless Steel 420 shim sheets are very corrosion resistant and precise. Generally available in the thickness of 0.1mm to 1mm, these are used for precise spacing and alignment in many engineering and manufacturing applications.
Stainless Steel 420 polished plates have excellent corrosion resistance and a reflective finish. Available in thicknesses ranging from 1mm to 10mm, they are used for decorative and high-visibility applications where aesthetic quality and resistance to oxidation are critical.
Ed Stainless is highly concerned with the customer experience and delivers that with adequate documentation of its premium-quality Stainless Steel 420 Sheets and Plates.
