304/304L - American Special Metals

304/304L. Common Trade Names:304 Stainless, 304L Stainless. Austenitic stainless, low carbon for as-welded corrosion resistance. AISI SS 304 / 304L S30400 / S30403 1.4304 / 1.4306 StardustJul 27, 2015 · SS 304 is considered the basic stainless steel alloy, composed of 18% chromium and 8% nickel. These components also give cause for 304 to be referred to as 18/8. The remainder of its composition is made up of carbon, manganese, silicon and very small amounts of phosphorous and sulfur.

This means grades like stainless steel 304, which contain nickel as high as 8% would by default have an FCC microstructure. Grade 304 Stainless Steel Properties, Tensile Yield There are several variants of 304 grade stainless steel, such as ultra-low-carbon version type 304L, nitrogen-containing version 304N, 304H with improved creep performance, and type 302 with higher carbon content. The second most widely used 316 grade stainless steel, compared with AISI 304, reduced chromium content, increased nickel content, and added 2-3% molybdenum.

Stainless Steel - Grade 304 (UNS S30400)

Oct 23, 2001 · The most everyday use of stainless steel is obviously in cutlery. Very cheap cutlery is made out of grades 409 and 430, with the finest Sheffield cutlery using specially produced 410 and 420 for the knives and grade 304 (18/8 stainless, 18% chromium 8% nickel) for the spoons and forks. What is Stainless Steel 304, 304L, 304H? - IntametFeb 08, 2017 · The key elements in 304 are Chromium and Nickel which give it excellent resistance to corrosion. It has good resistance to corrosion, it is malleable and ductile and has good weldability. The austenitic structure allows it to be deep drawn without intermediate annealing. It is also unnecessary to anneal it following welding thin sections.304/304L Stainless Steel AK Steelthan Type 304. Composition Type 304 (wt %) Type 304L (wt %) Carbon (C) 0.08 max. 0.03 max.
