Where high strength is required at temperatures above 500☌ and up to 800☌, grade 304H is recommended. 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. ☏)ġ8/8 stainless steel is widely used in petroleum & chemical industry, metallurgical machinery, aerospace industry, food processing equipment, instruments, household appliances and hardware manufacturing industries.ġ8/8 steel is made into a great many intermediate products such as steel sheet & plate, steel tube & pipe, steel bar & flat, rod & wire, etc.įinal products such as all kinds of kitchenware, tableware, medical device, machinery and parts, wire mesh, filter, architectural and decorative metal products, etc.Stainless steel types 1.4301 and 1.4307 are also known as grades 304 and 304L respectively.☏)Ĭoefficient of thermal expansion (CTE), 10 -6/K (μin./in.☏)Įlastic modulus (Modulus of Elasticity), GPa (10 6 psi).The tables below list 18-8 stainless steel mechanical properties including yield strength, tensile strength, elongation and hardness, etc.ġ8-8 stainless steel physical properties including density, melting point, magnetic, specific heat capacity, electrical resistivity, modulus of elasticity (elastic modulus), thermal diffusivity, thermal conductivity and coefficient of thermal expansion. Chemical Compositionġ8-8 stainless steel composition is given in table below. For full datasheet and specification, please view AISI 304, 304L. The tables below list the 18/8 stainless steel properties including chemical composition, physical and mechanical properties. 18/8 steel is the most widely used material, has excellent corrosion resistance in mild environments, and has good weldability and mechanical properties. The steel containing 18% chromium and 8% nickel includes 304 and its variants 304L, 304N and 304LN. 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).
