11/25/2023 0 Comments Tensile strength psi to mpa![]() Corrosion resistance & temperature effects 304 steel welds well using most welding methods, both with and without fillers, and it easily draws, forms, and spins into shape. It makes 304 steel essentially non-magnetic, and gives it a lower weakness to corrosion between grains thanks to austenitic steels being generally low carbon. Type 304 steel is austenitic, which is simply a type of molecular structure made from the iron-chromium-nickel alloy blend. Conversely, 304H is most used in elevated temperatures where the increased carbon content helps preserve its strength while hot. In general, 304L is reserved for large welding components that do not require post-welding annealing, as the low carbon percentages increase ductility. 304L has the lowest carbon percentage (0.03%), 304H has the highest (0.04-0.1%), and balanced 304 splits the difference (0.08%). Type 304 steel also comes into three main varieties: 304, 304L, and 304H alloys, which chemically differ based on carbon content. The density of 304 steel is around 8 g/cm 3, or 0.289 lb/in 3. Below is a chemical breakdown of 304 steel: Type 304 steel is part of the 3xx stainless steels or those alloys which are blended with chromium and nickel. To learn more about the differences among stainless steels, feel free to read our article on the type of stainless steel. In the case of stainless steels, they are often composed of 10 to 30% chromium and are made to withstand varying degrees of corrosion exposure. Steel names can get confusing, as the same alloy can have different identifiers depending on which system is used however, understand that the chemical composition of most alloy blends remains the same across classification systems. Stainless steels get their names from the American Iron & Steel Institute (AISI) and the Society of Automotive Engineers (SAE), who have separately created their own naming systems for steel alloys based on alloying elements, uses, and other factors. Designers will gain a better understanding of what this material is, how it works, and where 304 steel is applied in industry so that they can potentially select this material for use in their own projects. This article will explore the most common stainless steel, 304 steel, and will investigate its physical, mechanical, and working properties. One class of steels is known as the stainless steels, which utilizes chromium to reduce the usual corrosion experienced by most iron-based materials. ![]() Steel is composed of primarily carbon and iron, with other trace elements that can give steels unique properties from each other. We also ask that you refer to MatWeb's terms of use regarding this information.Īll the property values for this datasheet as they were originally entered into MatWeb.Steel is an alloy – that is, a metal made from blending so-called alloying elements into a base metal – and it provides a quite literal backbone for modern industry. We advise that you only use the original value or one of its raw conversions in your calculations to minimize roundingĮrror.

Some of the values displayed above may have been converted from their original units and/or rounded in order toĭisplay the information in a consistent format. Steels generally range between 9.5-12.6 µm/m☌ Varies from 0 - 100, Based on 100% machinability for AISI 1212 steel.

Values can range from 295 - 2400 MPa, depending on composition and heat treatment.ĪISI 1020 Steel. This is the value for AISI 1020, a mild steel. Varies widely with composition and heat treatment. Stainless steels typically have densities around 8 g/cc. Please click here if you are a supplier and would like information on how to add your listing to this material.ĭensity usually ranges from 7.8 - 7.9 g/cc for carbon and low alloy steels. In general, properties such as density, thermal conductivity, and electrical resistivity do not vary greatly with composition or heat treatment, whereas properties such as tensile strength, elongation, and hardness are highly dependent on composition and heat treatment. The properties listed below reflect typical properties for Steels. Other alloying elements such as Boron, Chromium, Cobalt, Columbium (Niobium), Copper, Molybdenum, Nickel, Nitrogen, Selenium, Tantalum, Titanium, Tungsten, and Vanadium are added to improve corrosion, high temperature, and mechanical properties of steel. The composition chart above represents typical ranges for basic steel constituents. Steels in general have a lower carbon content than cast irons, and lower amounts of impurities like phosphorus and sulfur.
