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.

One of the most versatile and commonly used stainless steels in the marketplace, Grade 304 stainless-steel is probably the most standard used alloy of this sort. Essentially, Grade 304 is an austenitic chromium alloy which is also known as an “18/eight” stainless because the make-up of the metal is 18% chromium and 8% nickel. It is necessary to know the mechanical properties of 304 and 304L stainless steel plate, ASTM A240. 304 chrome steel plate has a minimal tensile strength of seventy five ksi and a minimum yield strength at 0.2% of 30 ksi.

Continuous use of 304 and 304L chrome steel plate within the °F range just isn’t really helpful if aqueous corrosion resistance is essential. The Main difference between these two stainless steel plates is the quantity of carbon contained within each metal. 304 incorporates at most 0.08% carbon whereas 304 L accommodates at most 0.03% carbon. There can be a slight distinction in the nickel ranges within the stainless-steel plate. 304 chrome steel plate can contain up to 10.5% nickel whereas 304L can contain as much as 12% nitrogen. Grades 304 and 304L chrome steel plate is on the market in coil plates and plate mill plates at Penn Stainless Products.

304 chrome steel is the most versatile and extensively used austenitic stainless-steel on the earth, on account of its corrosion resistance. 304 stainless may be cheaper in worth in comparison with 316, one more reason for its popularity and widespread use. Grade ASTM A Stainless Steel is the usual “18/8” stainless; it is the most versatile and most generally used stainless steel, obtainable in a wider range of merchandise, types and finishes than some other. The balanced austenitic construction of Grade 304 allows it to be severely deep drawn with out intermediate annealing, which has made this grade dominant in the manufacture of drawn stainless components such as sinks, hollow-ware and saucepans. ASTM A240 Grade 304 is quickly brake or roll shaped into a wide range of parts for functions within the industrial, architectural, and transportation fields. This specification covers chromium, chromium-nickel, and chromium-manganese-nickel stainless steel plate, sheet, and strip for strain vessels and for general applications.

ASTM A240 Grade 304 Sheet is austenitic chrome steel stainless sheet and is available in many sizes, thickness and finishes. Aesteiron Steels is known as largest stockist and supplier of 304 stainless steel sheets and plates, We inventory more than 800 ton stock of SA 240 Gr 304 materials in 1mm to 120mm thickness and supply reduce to measurement with 2B finish and #4 end.

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.

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.

it additionally incorporates no more than 0.045% phosphorous, 0.03% sulfur and between 18.0% and 20% chromium. 304 stainless-steel plate is also made A240-304 stainless steel plates of between eight.0% and 10.5% nickel and at most 0.10% nitrogen. There are some key variations between 304 and 304L chrome steel plate.

• The time period ‘corrosion resistant metal’ is used when the alloy has lower than the 12% minimal of chromium, for instance within the aviation trade.
• Different from normal austenitic stainless steels, martensitic grades are magnetic.
• Type 304, with its chromium-nickel content and low carbon, is the most versatile and extensively used of the austenitic stainless steels.
