Refer to SSINAs Welding of Stainless Steels and Other Joining Methods for best practices. This grade of stainless steel is commonly used in the surgical industry, paper pulp industry as well as in the production of dyes and chemicals. Type 304 is sometimes also referred to as 18/8, a moniker that comes from its typical composition of 18% chromium and 8% nickel. This allows a designer to save weight and makes the alloy more cost competitive when compared to 316L or 317L. 304 stainless steel has excellent resistance to a wide range of atmospheric environments and AISI 304 stainless steel (UNS S30400) is the most widely used austenitic chromium-nickel stainless steel. Latent Heat of Fusion. 304 stainless steel has a yield strength of 215MPa, while 316 stainless steel has a yield strength of 290MPa. 18/8 stainless steel is also konwn as 304 stainless steel, it refers to the chemical composition of steel containing 18% chromium (Cr) and 8% nickel (Ni). AISI 304 Stainless Steel (UNS S30400) Wiki. The 316 material has 4% molybdenum content which gives it more corrosion resistance against chloride ion corrosion. Pros and Cons of 316 Stainless Steel. It is essentially non-magnetic when annealed and may become slightly magnetic when cold-worked. Typical uses of 304 stainless steel include sinks, kitchen equipment such as pans, tubing and much more. Because of the additional molybdenum in this steel, the overall performance of the steel is better than that of AISI 310 and AISI 304 stainless steel. The Stainless Steel 304 Seamless Pipe nominal bore size ranges from inches to 16 inches, the ERW pipes range from inches to 24 inches and the EFW pipes range from 6 inches to 100 inches. Thermal Properties. Its nominal composition is 18% chromium and 8% nickel, so it is also called 18/8 stainless steel. Stainless steel alloys are used predominantly in the automotive, aerospace and construction industries. The alloy has a higher yield strength and lower ductility than the austenitic steels so fabricators may find that higher forming forces, increased radius of bending, and increased allowance for springback are necessary. S30400 is the UNS number. The density of stainless steel 304 is 7.93 g/cm3, 7930 kg/m3, 0.286 lb/in3. Deep drawing, stretch forming, and similar processes are more difficult to perform on 2507 than on an austenitic stainless steel. (Brinell), elastic modulus and tensile strength. The yield strength is about twice that of austenitic stainless steels. Yield Strength (.2% offset): 130-150 KSI (896-1034 MPa) Elongation: 2-8% Alloy 304 can be supplied in a wide range of rolled tempered condition. The sizes of all pipes range from 1/8 inches to 30 inches. As noted in 304 stainless steel, the alloy reaches its melting point at the 2,550 F 2,650 F (1399 C 1454 C) range. There are different specifications such as the ASME SA240 316 Chequer Plate which is meant for high pressure and high temperature services. 304 is the AISI designation for this material. It is suited for use in temperatures between -50 and 300 C. This grade has a high mechanical strength and a AISI 316 (UNS S31600) and 316L (UNS S31603) are US steel grades, SUS 316 and SUS 316L are Japanese stainless steel grades. Tensile Strength: Yield (Proof) 230 to 860 MPa 34 to 120 x 10 3 psi. Naturally, the closer the steel is to its melting point, the more tensile strength it loses. The yield strength of duplex stainless steels is nearly double that of austenitic stainless steel. The steel containing 18% chromium and 8% nickel includes 304 and its variants 304L, 304N and 304LN. 290 J/g. The Stainless 316 Chequer Sheet is more corrosion resistance than the grade 304 plates. Duplex stainless steels have roughly twice the yield strength of austenitic stainless steel. Hardness This means that SS 316 is more suitable for making products subjected to more force than SS 304. The weight of 304 stainless steel is 7,930 kg per cubic meter. Maximum Temperature: Corrosion. 304/304L Stainless Steel Round, an economical grade of stainless that is ideal for all applications where strength and superior corrosion resistance is required. There are different widths of Yield strength is the maximum force you can apply to the metal before it changes shape permanently. What is 18/8 Stainless Steel. In comparison to austenitic stainless-steel Types 304 and 316, their mixed microstructure gives enhanced resistance to chloride stress corrosion cracking. They most commonly include chromium, nickel and molybdenum. Their mixed microstructure provides improved resistance to chloride stress corrosion cracking in comparison to austenitic stainless steel Types 304 and 316. AISI 304 stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. 302 Stainless Steel: Austenitic, non-magnetic, extremely tough and ductile, 302 Stainless Steel is Alloy 2205 duplex stainless steel plate is particularly suitable for applications covering the -50F/+600F temperature range. 304/304L Stainless Angle, is a hot rolled stainless angle shape with inside radius corners that is ideal for all structural applications where greater strength and superior corrosion resistance is required. 304 Stainless Round has a durable dull, mill finish that is widely used for all types of fabrication projects that are exposed to the elements - chemical, acidic, fresh water, and salt water environments. The difference between type 304 and 316 stainless steel is the incorporation of molybdenum of up to 3%. Stainless steel alloys resist corrosion, maintain their strength at high temperatures and are easy to maintain. It has corrosion resistance very close or slightly better than austenitic grades 304 and 316, but it has nearly doubled yield strength. Contact Ulbrich Wire Technical Service for details Welding 304 Stainless Steel. The best known grade is AISI 304 stainless, which contains both chromium (between 15% and 20%) and nickel (between 2% and 10.5%) metals as the main non-iron constituents.
