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.
For chrome steel sections which are welded closely, submit-weld annealing may be essential to supply maximum corrosive resistance. 304L stainless steel is in very massive demand as it may be utilized in severely corrosive conditions. Weld annealing is required for 304L stainless-steel, solely when there’s extreme stress load. The Chemical Composition of ASTM A240 grade 304L is P Max 0.045, Mn Max 2, C Max 0.03, S Max 0.03, Cr 18 – 20, Si Max 1 and Ni 8 – 12. The Ultimate Tensile Strength of ASTM A240 grade 304L is 564 MPa . The Yield Tensile Strength of ASTM A240 grade 304L is 210 MPa . Neeshaan Overseas are suppliers and fabricators of 304 Mirror Stainless Steel Sheet Metal.
The greater the carbon level of the material being welded, the greater the likelihood that the welding thermal cycle will outcome in the chromium carbide precipitation which is detrimental to corrosion resistance. To provide materials at one of the best stage of corrosion resistance, low carbon material should be used for materials put in service in the welded situation. Alternately, full annealing dissolves the chromium carbide and restores a excessive degree of corrosion resistance to the standard carbon content supplies. One of essentially the most versatile and commonly used stainless steels on the market, Grade 304 stainless-steel is the most commonplace used alloy of this kind. Essentially, Grade 304 is an austenitic chromium alloy which is also called an “18/eight” stainless as the make-up of the steel is eighteen% chromium and 8% nickel. Our production amenities are located in Finland, Germany, Sweden, the UK, the USA and Mexico, with a gross sales and repair heart community near our clients worldwide. Grade ASTM A Stainless Steel is the usual “18/8” stainless; it is the most versatile and most widely used chrome steel, obtainable in a wider vary of products, forms and finishes than another.

- There are totally different versions of the material with low carbon and high carbon content material.
- Opt for chrome steel inventory including stainless steel blanks, flats, bars, plates and sheet inventory from Grainger to assist enhance your firm’s productiveness.
- Shop a precision stainless-steel blank assortment in squares and rectangles which have assured tolerances and are machine ready, in order that they increase throughput by lowering your prep and setup time.
Heat exchangers, architectural trim and molding is also a standard place during which 304 and 304L chrome steel plate is used. 304 and 304L stainless-steel plate can be regularly utilized in woven or welded screens for mining, within the petroleum refining course of, quarrying and in water filtration techniques.
The surest warmth treatment to accomplish both requirements is the answer anneal which is conducted within the 1850°F to 2050°F vary (1010°C to 1121°C). Cooling from the anneal temperature must be at sufficiently high charges through °F (816°C – 427°C) to avoid reprecipitation of chromium carbides. A temperature gradient is produced in the materials being welded which ranges from above the melting temperature in the molten pool to ambient temperature at some distance from the weld.
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.

The SS 304L is the low carbon model of the stainless steel grade 304 which is there with utilizing within the excessive-temperature setting. This is the way that the sheet and plate are developed with the assistance of the alloying steel grades. Greenline Pipe and Fitting is catering all of the growing calls for of the purchasers for SS 304 Sheet. We are thought-about as the prominent manufacturer and supplier of the superior high quality of SS 304 Plate in addition to a sheet. The sheets and plates are offered to the clients in several specs like surface end, finish finish, dimensions, shapes, sizes, and thickness. Continuous use of 304 and 304L stainless steel plate in the °F vary isn’t recommended if aqueous corrosion resistance is necessary. 304 and 304L ASTM A240 chrome steel plate is a normal 18-8 materials – that means it accommodates 18% chromium and 8% nickel.
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.

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.
