While not as strong as some other steels available, the decreased strengths allow this metal to be easily worked into shape and manipulated without much difficulty. The yield strength is lower than the ultimate strength, as the yield strength describes the maximum stress before the material will deform permanently, whereas the ultimate strength refers to the maximum stress before fracture. The ultimate tensile and tensile yield strengths are a measure of a material's resilience to tensile (pulling) forces. The following section will briefly detail each of these parameters, and show how they are pertinent to the working properties of 304 steel. Table 1 shows some basic mechanical properties of 304 steel. Mechanical Properties Table 1: Summary of mechanical properties for 304 steel. If corrosion resistance is of high priority to a project, 304L is the best choice as its decreased carbon content reduces intergranular corrosion. 304 steels are not readily hardened by thermal treatment, but can be annealed to increase workability and cold worked to increase strength. This means that 304 steel mainly rusts not in high temperatures, but in aqueous solutions where continuous contact with corrosive materials can wear down the alloy. It also experiences increased pitting in warm temperatures (above 60 degrees Celsius), though the higher carbon grades (304H) mitigate this effect considerably. It can resist rusting in many different environments, only being majorly attacked by chlorides. Type 304 steel, being the most popular stainless steel, is naturally chosen for its corrosion resistance. 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. 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.
