304 stainless steel pipe7/15/2023 ![]() ![]() Oxidation resistance up to 1650☏ for continuous service and up to 1500☏ where cyclic heating is involved. ![]() This is the case with grade 304 and 304L stainless steel. The existence of these stainless steel variants can cause some confusion-especially when the names & formulations of two stainless steel alloys are almost the same. ![]() Each of these unique formulations of stainless steel offer some degree of corrosion resistance above and beyond that of plain steel. There are hundreds of different grades of stainless steel on the market. What’s the Difference Between Grade 304 ,304L & 304H Stainless Steel? *Maximum carbon content of 0.04% acceptable for drawn tubes In addition a number of other chemicals may be present but these are expressed as maximum permited levels with the exception of the increased quantity of carbon required in 304H - i.e. If the steel is to be deep drawn a higher percentage is better (9% or more). Where the steel is to be stretched formed a lower percentage (8%) of nickel should be selected. The nickel also improves high-temperature oxidation resistance makes the steel resistant to stress corrosion cracking. This is added to make the Austenitic structure more stable at normal temperatures. Chromium is the essential chemical in all stainless steel and it is that which forms the thin passive layer that makes the metal "stainless"ģ04 also contains 8-10.5% Nickel (Ni). The main constituents of 304 stainless steel - other than iron - are Chromium and Nickel.ģ04 contains 18 - 20% Chromium (Cr). Specifications - Stainless Steel 304/304L This alloy can be used in the as-welded condition without becoming susceptible to intergranular corrosion. Type 304L has a carbon content of 0.03% or less. However, the severity of corrosive environments may necessitate annealing after welding or the use of 304L. Type 304 finds extensive use in welding applications because the low carbon permits some exposure in the carbide precipitation range of 800☏ - 1500☏ without the need for post-annealing operations. Type 304 has slightly lower strength than 302 due to its lower carbon content. Cookie304 Stainless is a low carbon (0.08% max) version of basic 18-8 also known as 302.ĪSTM A213 TP304 Stainless Steel Seamless Tube is manufactured by seamless process used in high pressure environment, stainless steel TP304 grade is the most used material due to its high strength and excellent corrosion resistance.
