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.
This end is simple to maintain which makes it well-liked for every little thing from bakeware and flatware to plumbing fixtures, wheel covers, and many industrial functions similar to photo voltaic panels and other tools. One of essentially the most versatile and generally used stainless steels in the marketplace, Grade 304 stainless-steel is essentially the most normal used alloy of this sort. Essentially, Grade 304 is an austenitic chromium alloy which is also known as an “18/8” stainless as the make-up of the steel is 18% chromium and eight% nickel. Grade ASTM A Stainless Steel is the usual “18/8” stainless; it’s the most versatile and most generally used chrome steel, out there in a wider vary of merchandise, types and finishes than some other. ASTM A240 Grade 304 is instantly brake or roll shaped into a variety of elements for purposes in the industrial, architectural, and transportation fields.

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.
The Stainless Steel 304 Sheet also has manganese, carbon, silicon, sulfur, nitrogen and phosphorus in the composition. The material is strong and has 205MPa minimal yield energy and 515MPa minimal tensile strength generally. Grade 3CR12 chrome steel plates may be obtained in standard, sizzling-rolled annealed and pickled finish, and coils can be found in 2B or 2D finish. Black finish can be produced by hot-rolling the material A240-304 stainless steel plates, forsaking a dark oxidized surface on the metal. Grade 3CR12 with black finish has a great corrosion resistance and low friction and, hence, it’s appropriate for different wear purposes. Priminox Overseas is a well known trader and provider of SS Plates, which is being provided to our purchasers in a variety. ASTM A240 TP304 Plates are not very electrically or thermally conductive and is non-magnetic.

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.

Nitronic alloys scale back the tendency to gall through selective alloying with manganese and nitrogen. The austenitic stainless steels are warmth treated to take away the results of cold forming or to dissolve precipitated chromium carbides. The surest heat therapy to accomplish both requirements is the solution anneal which is carried out within the 1850°F to 2050°F range (1010°C to 1121°C). Cooling from the anneal temperature ought to be at sufficiently high rates 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 within the molten pool to ambient temperature at some distance from the weld. The larger the carbon degree of the material being welded, the higher the likelihood that the welding thermal cycle will result in the chromium carbide precipitation which is detrimental to corrosion resistance.
ASME SA S Plates are the low carbon model of the alloy, and are utilized for ease of fabrication. ASTM A H Plates has a carbon content material restricted to exclude the lower finish of the 310 range. ASME SA Plates usually include molybdenum to resist the corrosive results of NaCl or salt in seawater. ASTM A L Plates are a low-carbon subtype of marine grade stainless steel, which greater resistance to corrosion. ASME SA H Plates are a excessive carbon modification of Alloy 316 developed to be used in elevated temperature service. ASTM A LN Plates are a low carbon, nitrogen-enhanced version of Grade 316 molybdenum-bearing austenitic stainless-steel.
- Grade 3CR12 with black finish has a good corrosion resistance and low friction and, hence, it is suitable for various put on functions.
- Grade 3CR12 stainless steel plates can be obtained in normal, scorching-rolled annealed and pickled finish, and coils are available in 2B or 2D finish.
- Black end may also be produced by hot-rolling the material, forsaking a dark oxidized floor on the steel.
- ASME SA L Plates is a decrease carbon variant of SS 304, which can be welded without the resulting problem of carbon precipitation.
304l stainless steel pipe supplier
304 and 304L chrome steel plates are part of the austenitic family of stainless-steel and they are one of the most versatile and extensively used sorts of stainless plate. They are a comparatively low cost stainless product and used in a variety of applications. 304 grades have excellent low temperature properties and reply well to hardening by cold working. 304 stainless steel plate grades have good welding characteristics and publish weld annealing isn’t usually required to revive efficiency. 304 SS plates have wonderful corrosion resistance in a variety of different media. Typical specifications for 304 and 304L ss plates are ASTM A-240, ASME SA -240 and A666.
