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.
exposure of the 18-8 austenitic stainless steels to temperatures within the 800°F to 1500°F (427°C to 816°C) range may trigger precipitation of chromium carbides in grain boundaries. Such steels are “sensitized” and topic to intergranular corrosion when uncovered to aggressive environments. In some instances, the low carbon Alloy 304L might present a lower corrosion price than the higher carbon Alloy 304. The data for formic acid, sulfamic acid, and sodium hydroxide illustrate this. Otherwise, the Alloys 304, 304L, and 304H may be thought of to carry out equally in most corrosive environments. A notable exception is in environments sufficiently corrosive to trigger intergranular corrosion of welds and warmth-affected zones on prone alloys. The Alloy 304L is most well-liked to be used in such media in the welded condition for the reason that low carbon level enhances resistance to intergranular corrosion.
304 and 304L stainless steel plate can be incessantly used in woven or welded screens for mining, within the petroleum refining course of, quarrying and in water filtration techniques. This material can also be nicely fitted to the automotive and aerospace industries for structural use. 304 and 304L stainless-steel plate can also be used to produce nuts, bolts, screws, and different fasteners. 304 and 304L stainless-steel plate is also used as a construction material in specifically A240-304 stainless steel plates massive buildings and can be utilized in the dyeing, textile, and paper trade. Grade ASTM A Stainless Steel is the standard “18/eight” stainless; it is the most versatile and most widely used stainless-steel, available in a wider vary of merchandise, forms and finishes than some other. ASTM A240 Grade 304 is quickly brake or roll fashioned into quite a lot of parts for applications in the industrial, architectural, and transportation fields.

- The sheets and plates are provided to the clients in different specifications like surface end, end finish, dimensions, shapes, sizes, and thickness.
- This grade is an austenitic chromium alloy and it holds varied excellent options.
- Greenline Pipe and Fitting is catering all of the rising demands of the shoppers for SS 304 Sheet.
- This grade of sheet holds various features like warmth resistance, corrosion resistance, superior finishing, good energy and toughness at cryogenic temperature and lots of extra.
- Although each 304 and 304L chrome steel plate have similar chemical properties, there are a couple of noticeable differences.
Alloy SS 304 is the austenitic grade stainless-steel that is used to carry the stress vessels in the elevated temperatures. However, there are different components which the SS holds like carbon molybdenum and others.

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.
Low carbon content material extends the time necessary to precipitate a harmful stage of chromium carbides but doesn’t eliminate the precipitation response for material held for lengthy times within the precipitation temperature range. It is used extensively for residence and commercial appliances, including use in kitchen benches, sinks, troughs, and frying pans.
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.

304 stainless-steel plate is comprised of not more than 0.08% carbon whereas 304L stainless-steel plate incorporates a most of 0.03% carbon. The other primary difference in chemical composition between these two chrome steel plates grades is the amount of nickel. 304L chrome steel plate can have a maximum of 12.0% nickel while 304 stainless-steel plate can solely contain up to 10.5%. They both contain the same quantity of manganese, silicon, phosphorus, sulfur, and nitrogen. Each alloy represents a superb mixture of corrosion resistance and fabricability. This mixture of properties is the rationale for the in depth use of these alloys which symbolize nearly one half of the entire U.S. chrome steel manufacturing.
The properties which it holds are excessive tensile energy, nice toughness, stability within the elevated temperature, weldability, ductility, sturdiness, and others. We can supply ASTM A Stainless Steel Sheet and A240 Type 304 stainless steel plate in kind 304, 304L, 316 and 316L in the stock sizes listed below. 304 Stainless Steel Perforated stainless sheets also available in prepared inventory. All ASTM A Stainless Steel Plates can be delivered mirror polished if required. Type 304 and Type 304L have very related chemical and mechanical properties and are sometimes included on a single materials take a look at certificates when the actual properties of a stainless-steel plate meet the criteria of each sorts. Type 304L is a variation of Type 304 and has a lower carbon content material which improves weldability and lowers the risk of reduced corrosion resistance around the weld. Type 304L additionally has a barely lower yield and tensile power than Type 304.

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.
