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.
Aluminium plate, machined to form, forms the skins of jets and spacecraft gasoline tanks, and so on. It is used for storage tanks in many industries, partly as a result A240-304 stainless steel plates of some aluminium alloys become tougher at supercold temperatures. This property is especially helpful in holding cryogenic (very-low-temperature) materials.
Very low cost cutlery is made out of grades 409 and 430, with the best Sheffield cutlery using specially produced 410 and 420 for the knives and grade 304 (18/eight stainless, 18% chromium 8% nickel) for the spoons and forks. Grade 304 has glorious weldability by all commonplace fusion strategies, each with and with out filler metals.
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.

Once the metal is more than 6mm thick it is called plate steel. This type of material is utilized in circumstances whereby power and sturdiness are of the utmost significance. It is the commonest grade of chrome steel, supplied in an intensive forms of variants, varieties and floor finishes than another kind of stainless-steel. The mechanical properties of grade 304 stainless-steel Plate are displayed in the following desk.
We offer qualitative these SS 304 Plates in several configurations and dimensions which are being designed as per the national and international standard high quality of raw materials. OurASTM A240 TP304 Plateare part of the austenitic family of stainless steel and they’re some of the versatile and extensively used varieties of stainless Plate.
Product standard a240 304 stainless steel:For a240 304 stainless steel, the Ni element in its composition is very important, which directly determines the corrosion resistance of 304 stainless steel and its value.The most important elements in 304 are Ni and Cr, but they are not limited to these two elements. Specific requirements are specified by product standards. It is considered that 304 stainless steel can be considered as long as Ni content is more than 8% and Cr content is more than 18%. This is why the industry will call this kind of stainless steel 18 / 8 stainless steel. In fact, the relevant product standards have very clear provisions for 304, and these product standards have some differences for different shapes of stainless steel. Here are some common product standards and tests.

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.
Below are some common product standards and tests.

Stainless steels have a better resistance to oxidation and corrosion in many natural and man-made environments; nonetheless, you will need to select the right kind of stainless-steel for the use. There are over a hundred and fifty grades of stainless-steel, of which fifteen are probably the most used. Grade 316 chrome steel sheet and plate even have excessive nickel and chromium content, however the addition molybdenum further improves the corrosion resistance, especially against chlorides or chlorinated substances. These properties make grade 316 stainless steel sheet and plate a perfect selection for medical functions, marine environments, refining or chemical processing, and different extremely corrosive environments. We are providing UNS S30400 ASME/ASTM SA/A240 Stainless Steel 304 Plateto our shoppers. Ritinox stock stainless-steel, excessive nickel alloy, alloy steel, carbon steel, duplex and tremendous duplex plates and sheets. Stainless metal 2b end is a easy end versus the common brushed end seen on items like home equipment.
