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.
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.
304 SS plates have glorious corrosion resistance in a wide range of totally different media. Typical specifications for 304 and 304L ss plates are ASTM A-240, ASME SA -240 and A666. ASTM A240 Type 304 is the most typical of austenitic grades, containing approximately 18% chromium and eight% nickel.
ASTM A240 Grade 304 Sheet is austenitic stainless steel stainless sheet and comes in many sizes, thickness and finishes. Aesteiron Steels is named largest stockist and supplier of 304 stainless steel sheets and plates, We stock greater than 800 ton stock of SA 240 Gr 304 material in 1mm to 120mm thickness and provide reduce to measurement with 2B end and #4 finish. Cold rolled finishes are used on Astm A240 Type 304l Plate/ Coil products similar to Stainless Steel 304 sheet, plate or coil, with thickness less than about 5mm and usually less than 3mm. The smoother the surface finish of 304 Stainless Steel sheet perform good resistance to corrosion. We supply 304 Stainless Steel plate along with all 3 finishes which incorporates No. 2D, No. 2B and Bright Annealed Finish. SS 304 BA finish sheet is most nearly in a position to be matched by a mirror polish.
The Electrical Resistivity of ASTM A stainless steel is 7.2e-005 ohm-cm. ASTM A stainless-steel A240-304 stainless steel plates has a Magnetic Permeability of 1.008.
304L stainless steel is in very massive demand as it may be used in severely corrosive situations. Weld annealing is required for 304L stainless steel, solely when there’s excessive 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.
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.

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.

This is essentially the most used grade of all stainless steels on the planet. The sheets are robust, delicate corrosion resistant and have functions in quite a lot of industries. The Stainless Steel 304 Sheet additionally has manganese, carbon, silicon, sulfur, nitrogen and phosphorus in the composition. The materials is robust and has 205MPa minimal yield power and 515MPa minimal tensile strength in general. Type 304 and Type 304L have very related chemical and mechanical properties and are sometimes included on a single material test certificates when the actual properties of a stainless steel plate meet the factors of each sorts. Type 304L is a variation of Type 304 and has a decrease carbon content material which improves weldability and lowers the danger of lowered corrosion resistance around the weld.
Aesteiron can provide ss 304 1mm sheet worth higher than a vendor of Jindal stainless because our value is a minimum of 5% low in comparison with different dealers and distributors of Jindal in India as we lift the material in massive portions. We have hired retired engineers of JSW Steels Ltd so when you have any query related to 304 Stainless Steel Strips or SS 304 HR coil, AISI 304 cold rolled sheet can mail to our technical team at 304 stainless-steel sheet thickness tolerance can simply be discovered from a 304 stainless-steel thickness tolerance data sheet. 304 chrome steel plate has a Yield Tensile Strength of psi .
