S30408 stainless steel wire mesh grades, performance, uses, chemical composition and application introduction
S30403 corresponding grades 06Cr19Ni10 (S30408) 022Crl9Ni10 (S30403)
S30408 is equivalent to my country's 06Cr18Ni9 [according to GB/T 20878-2007, it has been changed to 06Cr19Ni10] stainless steel
S30408 stainless steel can be used as stainless heat-resistant steel and can withstand.
S30403 stainless steel wire mesh is an ultra-low carbon stainless steel with lower carbon content than 06Cr19Ni9. It has excellent resistance to intergranular corrosion and is a corrosion-resistant component that does not require heat treatment after welding.
S30403 Chemical Composition
Carbon C: ≤0.08
Silicon Si: ≤1.00
Manganese Mn: ≤2.00
Sulfur S: ≤0.030
Phosphorus P: ≤0.045
Chromium Cr: 18.00～20.00
Nickel: 8.00～11.00
S30408 stainless steel characteristics and uses
S30408 stainless steel can be used as stainless heat-resistant steel, can withstand repeated heating below 870℃, has good processing performance and weldability, and is the largest and most commonly used stainless steel variety. It is used in food equipment, general chemical equipment, industrial acid pipelines, containers, structural parts, and can be used to manufacture non-magnetic and low-temperature equipment components, atomic energy industry equipment, etc.
S30408 is composed of 18Cr-9Ni, which is the most widely used stainless steel and heat-resistant steel. It is used in food production equipment, chemical equipment, nuclear energy, etc. 304 is 1Cr18Ni9. The mechanism of stainless steel rust prevention is that the alloy elements form a dense oxide film, which isolates oxygen from contact and prevents further oxidation.
S30408 physical and mechanical properties: tensile strength σb (MPa) ≥ 520; yield strength σ0.2 (MPa) ≥ 205; elongation δ5 (%) ≥ 40 section shrinkage ψ (%) ≥ 60
Hardness: ≤187HB; ≤90HRB; ≤200HV
S30408 stainless steel is a very common stainless steel, also known as 18/8 stainless steel in the industry. 304 stainless steel is the most widely used chromium-nickel stainless steel with good corrosion resistance, heat resistance, low temperature strength and mechanical properties.
Although this type of stainless steel is very common in China, the name "304 stainless steel" comes from the United States. Many people think that 304 stainless steel is a model name in Japan, but strictly speaking, the official name of 304 stainless steel in Japan is "SUS304". Currently, there are three common marking methods on the market: 06Cr19Ni10, 304, and SUS304. Among them, 06Cr19Ni10 generally indicates national standard production, 304 generally indicates ASTM standard production, and SUS304 indicates Japanese standard production.
S30408 is a versatile stainless steel that is widely used in the production of
