In this instance 304L is recommended due to its resistance to carbide precipitation. However, continuous use at 425-860☌ is not recommended if corrosion resistance in water is required. Stress corrosion cracking can occur above 60☌.ģ04 has good resistance to oxidation in intermittent service up to 870☌ and in continuous service to 925☌. Pitting and crevice corrosion can occur in environments containing chlorides. Stainless Steel Grade 1.4301/304 also corresponds to the following designations but may not be a direct equivalent:ģ04 stainless steel is typically used in:īrewery, dairy, food and pharmaceutical production equipmentģ04 has excellent corrosion resistance in many environments and when in contact with different corrosive media. ![]() It is reasonable to expect specifications in these standards to be similar but not necessarily identical to those given in this datasheet.Ĭhemical Composition Spec: EN 10088-3:2005 1.4301 Steel Chemical Element ASTM, EN or other standards may cover products sold. Property data given in this document is typical for Bar and Section to EN 10088-3:2005. Some products such as plate and pipe may be available as “dual certified” material that meets the criteria for both 304 and 304L.ģ04H, a high carbon content variant, is also available for use at high temperatures. It is used in heavy gauge components for improved weldability. Type 304L is the low carbon version of 304. ![]() This property has resulted in 304 being the dominant grade used in applications like sinks and saucepans. Type 304 stainless steel is an austenitic grade that can be severely deep drawn. It is still sometimes referred to by its old name 18/8 which is derived from the nominal composition of type 304 being 18% chromium and 8% nickel. Type 304 is the most versatile and widely used stainless steel. X2CrNiMo17-12-2 (Material number: 1.Stainless steel types 1.4301 and 1.4307 are also known as grades 304 and 304L respectively. AISI 316L Mechanical PropertiesĪnnealed, Cold finished, Dia ≤ 12.7 mm (0.5 in.)Īnnealed, Cold finished, Dia > 12.7 mm (0.5 in.)ĪISI 316L stainless steel equivalent materials are listed in the table below, including European EN (Germany DIN, British BSI, French NF…), ISO, Japanese JIS and Chinese GB standard (For reference). The following tables list AISI 316L grade stainless steel mechanical properties such as yield strength, tensile strength, elongation and hardness, etc. Grade 316L stainless steel physical properties are listed in the table below such as density, melting point, specific heat, electrical resistivity, elastic modulus (modulus of elasticity), thermal conductivity, etc. Chemical Composition 316L Stainless Steel Composition, % Type 316L stainless steel density is 0.289 lb/in3 (8.0 g/cm3) melting point is 1375-1400 ☌ (2500-2550 ☏) 0.2% yield strength is minimum 25 ksi (170 MPa) in annealed and hot finished condition, minimum 45 ksi (310 MPa) in annealed and cold finished condition Minimum tensile strength is 70 ksi (485 MPa) in annealed and hot finished condition, ≥ 90 ksi (620 MPa) in annealed and cold finished condition Maximum Brinell hardness is 217 HB, Maximum Rockwell hardness is 90 HRBW Thermal conductivity is 12.1 W/m However, when it is heated and kept in the sensitization temperature range for a long time during use, a large amount of carbides will precipitate, so it is usually recommended to use it below 425 ☌ (800 ☏). SS316L is resistant to carbide precipitation in the temperature range of 425-870 ☌ (800-1600 ☏), so normal welding can be performed without reducing corrosion resistance. The addition of molybdenum can provide pitting resistance in phosphoric acid and acetic acid and dilute chloride solutions and corrosion resistance in sulfurous acid. It is recommended for parts that cannot be annealed after welding in certain corrosive environments. AISI 316L stainless steel is a modified ultra-low carbon Cr-Ni-Mo series austenitic stainless steel based on AISI 316.
