I assume you mean 18-8.
18-8 steel is stainless steel with about 18% chromium amnd 8% nickel. 304 is in that category and is indeed an 18-8 steel. There are other 18-8 steels, such as 301 and 302, so while all 304 steels are 18-8 not all 18-8 steels are 304
Japanese standard for stainless steel grade 304.
UTS of 304L Stainless Steel is 586MPa UTS of 304 Stainless Steel is 621MPa
1810 Stainless Steel is the European grade that is equivalent to AISI 304 Stainless Steel. It's the most common stainless steel going. Here's the rundown: Fe, <0.08% C, 17.5-20% Cr, 8-11% Ni, <2% Mn, <1% Si, <0.045% P, <0.03% S
According to the Metals Handbook of the American Society of Testing and Materials, 316 Stainless has a tensile strength of 85,000 pounds per square inch.
Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst theaustenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. Grade 316L, the low carbon version of 316, is immune from sensitisation (grain boundary carbide precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm). There is commonly no appreciable price difference between 316 and 316L stainless steel. The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures. Compared to chromium-nickel austenitic stainless steels, 316L stainless steel offers higher creep, stress to rupture and tensile strength at elevated temperatures. EnduraMet(R) 316LN stainless is a nitrogen-strengthened version of Type 316L stainless. By means of solid solution strengthening, the nitrogen provides significantly higher yield and tensile strength as annealed than Type 316L without adversely affecting ductility, corrosion resistance or non-magnetic properties. In the hot rolled unannealed condition, yield strength of 75 ksi (518 MPa) or higher can be achieved for bar diameters up to 1.375in (34.925mm). The foregoing information was gathered from two different web locations arrived at by searching for "stainless steel rebar" and "316LN stainless steel." It appears that Type 316 is a standard stainless steel, 316L is a low carbon stainless steel, and 316LN is a low carbon nitrogen strengthened stainless steel.
Nothing there both the same
Japanese standard for stainless steel grade 304.
For example the stainless steel grade 304 with 18 % chromium and 8 % nickel.
Stainless steel that is 304 grade is basically Stainless steel that is food-safe. Most stainless steel water bottles are made from 304 grade stainless steel, as well as cutlery, knives, and watches.
UTS of 304L Stainless Steel is 586MPa UTS of 304 Stainless Steel is 621MPa
Stainless steel's melting points can vary from a low of 1375°C for grade 316 steel to a high of 1510°C for grade 430. The most common grade, 304, has a melting point of 1400-1450°C
yes
The SS 304 pipes are high on strength with a minimum yield strength 205MPa and provide sustainability with basic tensile strength of 515MPa. Type 304 grade of stainless steel pipe is built in various shapes like round, square, rectangular, and more in various forms, like seamless, welded, etc. Western Steel Agency is a Top Stainless Steel Pipe Fittings Manufacturers in India.
Stainless steel does not usually rust. It will pit and also undergo crevice corrosion, so would need more information on the environment it is to be placed in. Also would need to know what grade of stainless steel - 302, 304, 316, 316L?
Compared to 304 grade stainless steel, the 316 has higher strength, can withstand higher temperatures, and yes it can resist corrosion better. One factor is the molybdenum content in the 316 grade which gives it the overall corrosion resistant properties. The downside, 316 stainless steel grade is way more expensive than 304.
Current price of stainless steel as of May 24 2011 in the United States is around 70 cents per pound. There are various types of stainless steel such as 304, 316 etc. 304 stainles steel scrap will pay you less at the scrap yard then 316 stainless steel. Always know or have tested your stainless steel scrapbefore selling to the recycling yard.
Stainless Steel 304 Seamless Pipes come in various types based on their manufacturing processes and applications. Some common types include standard seamless pipes, precision seamless pipes, cold drawn seamless pipes, and high-pressure seamless pipes. Each type offers specific benefits and is suited for different industrial and commercial purposes.
