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.
Refer to chemical composition 316 stainless steel contains factor Mo, which is the rationale that 316/316L has better corrosion resistance than 304/304L, especially in high temperature conditions. Therefore, engineers usually choose 316 materials in excessive temperature environments. However, if the surroundings consist sulfuric acid, do not use 316/316L for high temperature, as the Molybdenum might be easily reacts to high-priced sulfur ions and kind sulfides. ASTM A240 steel plate covers Austenitic Steels, Ferritic steels and Martensitic Steels. Amardeep steel is among the leading Manufacturer, Exporter and Supplier of High Quality ASTM A240 TP 304 Stainless Steel Plates and Sheets.

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.

Grade ASTM A Stainless Steel is the usual “18/eight” stainless; it’s the most versatile and most widely used chrome steel, available in a wider vary of merchandise, forms and finishes than any other. ASTM A240 Grade 304 is quickly brake or roll fashioned into a variety of parts for purposes in the industrial, architectural, and transportation fields. exposure of the 18-eight austenitic stainless steels to temperatures within the 800°F to 1500°F (427°C to 816°C) vary could cause precipitation of chromium carbides in grain boundaries. Such steels are “sensitized” and subject to intergranular corrosion when exposed to aggressive environments. Alloys 304, 304L, and 304H are also immune to moderately aggressive natural acids similar to acetic and lowering acids similar to phosphoric. The 9 to 11 % of nickel contained by these 18-8 alloys assists in providing resistance to moderately reducing environments. The more highly decreasing environments similar to boiling dilute hydrochloric and sulfuric acids are shown to be too aggressive for these supplies.

Our SS 304 Strips and coils are used in high most dairy industries in India like Amul and Mother Dairy. We have hired 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 chilly rolled sheet can mail to our technical team at Although each 304 and 304L stainless-steel plate have comparable chemical properties, there are a number of noticeable differences. 304 stainless steel plate also contains at most 2.0% manganese and 0.seventy five% silicon. it additionally contains not more than 0.045% phosphorous, 0.03% sulfur and between 18.0% and 20% chromium. 304 chrome steel plate is also made of between eight.0% and 10.5% nickel and at most 0.10% nitrogen. There are some key variations between 304 and 304L stainless-steel plate.
There are completely different grades and floor finishes of stainless-steel, relying on where will probably be used. Stainless steels have a better resistance to oxidation and corrosion in many pure and man-made environments; however, you will need to select the proper kind of stainless-steel for the use. There are over one hundred fifty grades of stainless-steel, of which fifteen are probably the most used. The Alloys 304, 304L, and 304H austenitic stainless steels present useful resistance to corrosion on a variety of moderately oxidizing to moderately lowering environments. The alloys are used widely in gear and utensils for processing and dealing with of meals, beverages, and dairy merchandise. Heat exchangers, piping, tanks, and different process gear in contact with fresh water also make the most of these alloys. The chromium content material promotes the material’s appreciable resistance to the effects of corrosion and oxidation.
