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.
The 1.4301 and 1.4307 have carbon ranges of 0.07% maximum and 0.030% most, respectively. The chromium and nickel ranges are similar, nickel for both grades having an 8% minimum. This reduces the ferrite content material of the steel and has discovered to be essential for some chemical processes. Alloy 304 is the standard alloy since AOD know-how has made decrease carbon levels more simply attainable and economical. Alloy 304L is used for welded merchandise which may be exposed to circumstances which may trigger intergranular corrosion in service. Alloy 304H is a modification of Alloy 304 in which the carbon content material is managed to a range of 0.04-0.10 to offer improved high temperature power to components exposed to temperatures above 800°F. Our SS 304 Strips and coils are utilized in high most dairy industries in India like Amul and Mother Dairy.
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 and 304L stainless-steel plate is also used as a building materials in specifically massive buildings and is also utilized within the dyeing, textile, and paper business.

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.

The balanced austenitic construction of Grade 304 allows it to be severely deep drawn without intermediate annealing, which has made this grade dominant in the manufacture of drawn stainless parts corresponding to sinks, hollow-ware and saucepans. ASTM A240 Grade 304 is quickly brake or roll fashioned into quite a lot of components for purposes in the industrial, architectural, and transportation fields. The Main distinction between these two chrome steel plates is the quantity of carbon contained inside every steel. 304 contains at most 0.08% carbon whereas 304 L accommodates at most 0.03% carbon.
ASTM A240 Grade 304 Sheet is austenitic chrome steel stainless sheet and is available in many sizes, thickness and finishes. Aesteiron Steels is called largest stockist and supplier of 304 stainless steel sheets and plates, We stock greater than 800 ton stock of SA 240 Gr 304 materials in 1mm to 120mm thickness and supply minimize to size with 2B finish and #4 end. One of essentially the most versatile and generally used stainless steels available on the market, Grade 304 stainless steel is essentially the most normal used alloy of this type. Essentially, Grade 304 is an austenitic chromium alloy which is also called an “18/eight” stainless as the make-up of the steel is eighteen% chromium and 8% nickel. The chromium content material promotes the material’s appreciable resistance to the results of corrosion and oxidation.

We have about 3000tons each thickness and dimension stainless plates and huge warehouse. For materials exposed inland, gentle industrial, or milder service, minimal upkeep is required. Only sheltered areas need occasional washing with a stream of pressurized water. In heavy industrial areas, frequent washing is advisable to take away dirt deposits which could finally trigger corrosion and impair the floor appearance of the stainless steel.
The time period ‘corrosion resistant steel’ is used when the alloy has less than the 12% minimal of chromium, for instance within the aviation business. There are totally different grades and floor finishes of chrome steel, depending on where will probably be used. Stainless steels have the next resistance to oxidation and corrosion in many natural and man-made environments; nonetheless, it is very A240-304 stainless steel plates important select the correct type of stainless-steel for the use. There are over one hundred fifty grades of stainless-steel, of which fifteen are essentially the most used. publicity of the 18-8 austenitic stainless steels to temperatures within the 800°F to 1500°F (427°C to 816°C) vary could trigger precipitation of chromium carbides in grain boundaries.

- ASTM A Sheets is among the most versatile and commonly used stainless steel grades available in the market.
- This grade is an austenitic chromium alloy and it holds varied excellent options.
- Stainless Steel 304 Sheet is made up of an austenitic chrome steel that has 18% chromium and 8% nickel in the composition.
- This grade of sheet holds various options like warmth resistance, corrosion resistance, superior ending, good power and toughness at cryogenic temperature and many more.
Alloy SS 304 is the austenitic grade stainless steel that’s used to carry the stress vessels within the elevated temperatures. However, there are completely different components which the SS holds like carbon molybdenum and others. The SS 304L is the low carbon version of the chrome steel grade 304 which is there with utilizing within the high-temperature setting. This is the way in which that the sheet and plate are developed with the help of the alloying metal grades. Essentially, Grade 304 is an austenitic chromium alloy which is also referred to as an “18/8” stainless because the make-up of the metal is eighteen% chromium and 8% nickel. 304 and 304L ASTM A240 chrome steel plate is a standard 18-8 materials – which means it accommodates 18% chromium and eight% nickel.

When 316L metal of low carbon content material is only a little higher than 316 steel on energy stage. Another distinction, 316l can be used for weld remedy because it incorporates decrease carbon. Exposure of the 18-8 austenitic stainless steels to temperatures in the 800°F to 1500°F (427°C to 816°C) vary could trigger precipitation of chromium carbides in grain boundaries. Such steels are “sensitized” and subject to intergranular corrosion when exposed to aggressive environments.
