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 grade is eighteen/eight normal metal and it is extensively used for industrial and engineering purposes. No doubt stainless steel 304/304L sheets, plates, coils have turn into the popular product among the many industrialists. The item is manufactured by Sanghvi Engineerings making effective use of superior high quality of stainless steel that is supplied by dependable retailers together with the use of newest and trendy know-how. ASME SA Grade 304L Sheets and Plates are used to make chemical containers, sea water or salt water circumstances. Nr. 1.4307 alloy comes in the category of Austenitic Stainless Steel which offers good power on excessive temperature as nicely corrosion resistance to sulphuric acid.
This combination of properties is the reason for the intensive use of those alloys which represent nearly one half of the whole U.S. stainless-steel manufacturing. The 18-eight stainless steels, principally Alloys 304, 304L, and 304H, can be found in a variety of product varieties including sheet, strip, and plate. The alloys are covered by quite a A240-304 stainless steel plates lot of specifications and codes referring to, or regulating, construction or use of equipment manufactured from these alloys for particular circumstances. Food and beverage, sanitary, cryogenic, and pressure-containing applications are examples. Stainless Steel 304 Sheet is made up of an austenitic stainless steel that has 18% chromium and eight% nickel in the composition.
Stainless metal 304 sheetsare essentially the most versatile and generally used stainless-steel sheet that comes in a wide variety of forms and finishes than any other grade of chrome steel sheet. Because of its sturdiness and strong formation, yow will discover this sheet in vital industries. However, the key issues that embody in its manufacturing course of and what are its salient options are distinguished under. It is provided using only two course of- cold rolled in addition to hot rolled. Now, we are talking about its thickness that is from 0.6 mm to eighty mm and the width or measurement is as per your needs. ASTM a240 SS 304 / 304l plates are also being supplied with the personalized decisions. Thus now, any patron can get it as per their selection, need and finances from us.
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.
Our SS 304 Strips and coils are utilized in high most dairy industries in India like Amul and Mother Dairy. Aesteiron can provide ss 304 1mm sheet worth better than a supplier of Jindal stainless as a result of our price is a minimum of 5% low compared to different dealers and distributors of Jindal in India as we lift the fabric in large quantities. We have employed retired engineers of JSW Steels Ltd so if you have any question associated to 304 Stainless Steel Strips or SS 304 HR coil, AISI 304 cold rolled sheet can mail to our technical team at So the 304 Stainless Steel Sheet Price is lower in comparison with other grades of stainless steels and all metallic merchandise in general.
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 standard
Grade ASTM A Stainless Steel is the standard “18/8” stainless; it is the most versatile and most widely used chrome steel, out there in a wider range of products, varieties and finishes than any other. ASTM A240 Grade 304 is readily brake or roll fashioned into a variety of components for purposes within the industrial, architectural, and transportation fields. Continuous use of 304 and 304L stainless-steel plate in the °F vary just isn’t recommended if aqueous corrosion resistance is essential.
304 stainless-steel plate has a minimum tensile energy of seventy five ksi and a minimum yield energy at 0.2% of 30 ksi. This type of stainless steel plate has a most Brinell hardness of 201 and a Rockwell B hardness of 92. 304L stainless steel plate has a minimal tensile strength of 70 ksi and a yield power at 0.2% of 25 ksi.
types of 304 stainless steel
- Nr. 1.4307 alloy comes within the class of Austenitic Stainless Steel which provides good power on excessive temperature as well corrosion resistance to sulphuric acid.
- ASME SA Grade 304L Sheets and Plates are used to make chemical containers, sea water or salt water conditions.
- 304L Stainless Plate is a perfect and economical metal plate to make chemical storage containers and milk tankers.
Aluminium plate, machined to form, types the skins of jets and spacecraft fuel tanks, etc. It is used for storage tanks in many industries, partly as a result of some aluminium alloys turn out to be tougher at supercold temperatures. This property is especially useful in holding cryogenic (very-low-temperature) supplies. The Alloys 304, 304L, and 304H austenitic stainless steels provide useful resistance to corrosion on a variety of reasonably oxidizing to moderately decreasing environments. The alloys are used widely in tools and utensils for processing and handling of meals, beverages, and dairy products. Heat exchangers, piping, tanks, and different process tools involved with recent water also utilize these alloys.

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.
