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.
304 stainless steel plate is comprised of no more than 0.08% carbon whereas 304L stainless steel plate contains a maximum of 0.03% carbon. The different main distinction in chemical composition between these two stainless-steel plates grades is the quantity of nickel. 304L stainless steel plate can have a most of 12.0% nickel while 304 stainless steel plate can only contain up to 10.5%. They each comprise the same amount of manganese, silicon, phosphorus, sulfur, and nitrogen.
In most purposes the metal is used where its corrosion resistance provides long lasting appearance and service life. The ease of cleaning and of maintaining a hygienic floor on the steel make it wonderful for many functions. We are engaged in producing and selling stainless steel, put on resistant metal plate, weathering metal plate, excessive power carbon steel plate, alloy metal, boiler and Pressure vessel metal plate, we aslo produce metal pipes, coils and so on. Type 304/304L is the modern model of 18-eight stainless-steel containing approximately 18% chromium and eight% nickel and is essentially the most commonly specified stainless-steel used all through the world.
The Stainless Steel 304 Sheet also has manganese, carbon, silicon, sulfur, nitrogen and phosphorus within the composition. The material is powerful and has 205MPa minimal yield energy and 515MPa minimum tensile strength generally. 304 stainless steel plates are a piece of the austenitic group of stainless-steel and they’re a standout amongst the most flexible and customarily utilized assortments of stainless plate. They are a moderately minimal effort stainless merchandise and utilized as a part of an assortment of utilizations. 304 evaluations have unbelievable low temperature properties and react nicely to solidifying by icy working.
We keeps Ready Stock Inventory of ASTM A Stainless Steel Plates in India, SS Plates. Distributor Prime ASTM A Stainless Plate from Aperam, Acerinox, Jindal, Outokumpu Brand Material in Hot Rolled and Cold Rolled Form with No.1 Finish, Mill Finish, 2B Finish Available to Supply Worldwide. Clear labels are tagged on the outside of the package deal for easy A240-304 stainless steel plates identification of the quantity and product I.D. Exposure of the 18-eight austenitic stainless steels to temperatures within the 800°F to 1500°F (427°C to 816°C) range could trigger precipitation of chromium carbides in grain boundaries. Such steels are “sensitized” and subject to intergranular corrosion when uncovered to aggressive environments.
304l steel
Therefore, engineers usually select 316 materials in excessive temperature environments. However, if the setting consist sulfuric acid, don’t use 316/316L for prime temperature, as the Molybdenum will be easily reacts to excessive-priced sulfur ions and type sulfides.
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 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 material is typically nonmagentic however may turn into slightly magnetic when cold worked.
- The 304 stainless-steel sheet has a #4 brushed end, has been annealed, meets American Society for Testing and Materials International ASTM A240 and American Society of Mechanical Engineers ASME SA240 specs, and has a normal tolerance.
- The #4 brushed end has a moderately reflective look with fantastic parallel polishing traces.
- Typical specifications for 304 and 304L ss plates are ASTM A-240, ASME SA -240 and A666.
- The 304 stainless-steel grade is a basic-purpose materials that combines corrosion resistance, weldability, and formability, making it the most generally used grade of stainless steel.
304 2b finish
The Alloy 304L is most well-liked for use in such media within the welded condition for the reason that low carbon stage enhances resistance to intergranular corrosion. Yes, it’s attainable to buy twin licensed stainless steel plate in grades 304 and 304L.

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.

The knowledge for formic acid, sulfamic acid, and sodium hydroxide illustrate this. Otherwise, the Alloys 304, 304L, and 304H may be considered to carry out equally in most corrosive environments. A notable exception is in environments sufficiently corrosive to trigger intergranular corrosion of welds and heat-affected zones on susceptible alloys.
304 Stainless Plate, probably the most broadly used of the stainless and warmth resisting steels. 304 stainless plate offers good corrosion resistance to many chemical corrodents in addition to industrial atmospheres and marine environments Typical specifications for 304 Plate and 304L Stainless Steel Plate are ASTM A-240, ASME SA -240 and A666.
