1/17/2024 0 Comments 304 stainless composition![]() ![]() The austenitic stainless steels are also considered to be the most weldable of the high-alloy steels and can be welded by all fusion and resistance welding processes. Ideal for a wide variety of home and commercial applications, Alloy 304 exhibits excellent corrosion resistance and has a high ease of fabrication, outstanding formability. It is magnetic, but less magnetic than steel. It is less electrically and thermally conductive than carbon steel. ![]() Alloy 304 is the most versatile and widely used alloy in the stainless steel family. The steel contains both chromium (between 18 and 20) and nickel (between 8 and 10.5) 1 metals as the main non- iron constituents. 420 stainless steel contains 12-14 chromium and 0.12-0.35 carbon, making it a hard, corrosion-resistant alloy often used to manufacture medical equipment, cutlery, and firearms. The main difference between 420 and 304 stainless steel is their chemical composition. It is the standard “18/8 stainless” that is commonly found in pans and cooking tools. 304 is characterized by a chemical composition of 18 of chromium, a nickel content of 8, and a maximum of 0.08 of. Difference Between 420 Stainless Steel and 304 Composition. ![]() MatWeb data and tools provided by MatWeb, LLC.Alloy 304 a T-300 series stainless steel austenitic, which has a minimum of 18% chromium and 8% nickel. We also ask that you refer to MatWeb's disclaimer and terms of use We advise that you only use the original value or one of its raw conversions in yourĬalculations to minimize rounding error. Users requiring more precise data for scientific orĮngineering calculations can click on the property value to see the original value as well as raw conversions Order to display the information in a consistant format. Some of the values displayed above may have been converted from their original units and/or rounded in Low carbon content means less carbide precipitation in the heat-affected zone during welding and a lower susceptibility to intergranular corrosion.Īpplications: beer kegs, bellows, chemical equipment, coal hopper linings, cooking equipment, cooling coils, cryogenic vessels, dairy equipment, evaporators, flatware utensils, feedwater tubing, flexible metal hose, food processing equipment, hospital surgical equipment, hypodermic needles, kitchen sinks, marine equipment and fasteners, nuclear vessels, oil well filter screens, refrigeration equipment, paper industry, pots and pans, pressure vessels, sanitary fittings, valves, shipping drums, spinning, still tubes, textile dyeing equipment, tubing.Ĭorrosion Resistance: resists most oxidizing acids and salt spray.Īt 20☌ (68☏) 1.16E-04 at 650☌ (1200☏) Essentially non-magnetic, becomes slightly magnetic when cold worked. High ductility, excellent drawing, forming, and spinning properties. Better corrosion resistance than Type 302.
