Gangsteel produce ASTM A240 304 Stainless steel plates, S30400, A240 Type 304 Stainless steel cutting parts by water cutting, laser cutting and cnc cutting. ASTM a240 (chromium and chromium nickel stainless steel plate, sheet, and strip for pressure essels and general applications. a240 304 stainless steel is a common material in stainless steel with a density of 7.93g/cm3, which is also called 18 / 8 stainless steel in the industry. High temperature resistant 800 ��, with good processing performance and high toughness, it is widely used in industry, furniture decoration industry and food and medical industry.
06cr19ni10 and SUS304 are the common marking methods on the market, among which 06cr19ni10 generally refers to national standard production, 304 generally refers to ASTM standard production, and SUS 304 refers to Japanese standard production.
304 is a kind of universal stainless steel, which is widely used to make equipment and parts with good comprehensive performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 18% chromium and more than 8% nickel. The stainless steel is produced according to ASTM 304.
Both hardness and tensile power can be increased by cold working, which may trigger slight magnetism. The twin licensed 304/304L sheet meets specifications for both 304 and 304L chrome steel, and could also be interchanged and used safely for either grades software. We are Manufacturer, Supplier & Exporter of SS 304 / 304L Sheets Plates, which has higher quick and long term creep strength. Stainless Steel 304 Plates is a modification of essentially the most broadly utilized “18-8” chromium-nickel austenitic stainless steel. The merchandise is manufactured by Mangalam Metal making efficient use of superior high quality of stainless steel that is provided by dependable retailers together with the use of latest and fashionable technology.
There are completely different grades and floor finishes of stainless-steel, depending on the place it is going to be used. Stainless steels have the next resistance to oxidation and corrosion in lots of pure and man-made environments; nonetheless, it is very important select the correct sort of stainless steel for the use. There are over one hundred fifty grades of chrome steel, of which fifteen are the most used. publicity of the 18-8 austenitic stainless steels to temperatures in the 800°F to 1500°F (427°C to 816°C) vary may trigger precipitation of chromium carbides in grain boundaries. Such steels are “sensitized” and topic to intergranular corrosion when exposed to aggressive environments. The Alloys 304, 304L, and 304H austenitic stainless steels present helpful resistance to corrosion on a wide range of moderately oxidizing to moderately reducing environments.

For a240 304 stainless steel, the Ni element in its composition is very important, which directly determines the corrosion resistance and value of 304 stainless steel.
The most important elements in 304 are Ni and Cr, but they are not limited to these two elements.
Specific requirements are stipulated by product standards.
The common judgment in the industry is that as long as the Ni content is greater than 8% and the Cr content is greater than 18%, it can be considered as 304 stainless steel.
This is why the industry calls this type of stainless steel 18/8 stainless steel.
In fact, the relevant product standards have very clear regulations on 304, and these product standards have some differences for different shapes of stainless steel.

The alloys are coated by a wide range of specifications and codes referring to, or regulating, development or use of equipment manufactured from these plates for specific situations. Food and beverage, sanitary, cryogenic, and strain-containing applications are widespread examples.
The Main distinction between these two chrome steel plates is the amount of carbon contained within each metallic. 304 incorporates at most 0.08% carbon while A240-304 stainless steel plates 304 L accommodates at most 0.03% carbon. There can be a slight distinction within the nickel ranges in the chrome steel plate.
This sort of chrome steel plate has a maximum Brinell hardness of 201 and a Rockwell B hardness of ninety two. 304L chrome steel plate has a minimum tensile power of 70 ksi and a yield power at 0.2% of 25 ksi. This stainless-steel plate also has an elongation of 40%, a most hardness of 201 on the Brinell scale and a hardness of 92 on the Rockwell B scale.
