We typically inventory 304 and 304L stainless-steel coil plates in widths including 36”, 48”, 60”, seventy two” and a pair of meters (78.74”). Stainless metal plate coil is often inventoried in lengths of in 96”, one hundred twenty”, one hundred forty four”, and 240”. 304 and 304L plate mill plate can be obtainable for purchase, in widths forty eight”, 60”, seventy two” and a couple of meters, along with 84”, ninety six” and a hundred and twenty”. The plates are in 96”, a hundred and twenty”, one hundred forty four”, and 240” in size but custom lengths are commonly out there. In most functions the steel is used where its corrosion resistance provides lengthy lasting look and repair life.
It is used extensively for residence and commercial home equipment, together with use in kitchen benches, sinks, troughs, and frying pans. 304 and 304L chrome steel plate has a variety of software within the food processing industries as nicely, together with use in tools, significantly seen in beer brewing, wine making and milk processing.
Cooling from the anneal temperature ought to be at sufficiently excessive rates through °F (816°C – 427°C) to keep away from reprecipitation of chromium carbides. 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 vary of merchandise, varieties and finishes than some other. ASTM A240 Grade 304 is instantly brake or roll formed into a variety of parts for applications within the industrial, architectural, and transportation fields. Our SS 304 Strips and coils are used in prime most dairy industries in India like Amul and Mother Dairy. Aesteiron can supply ss 304 1mm sheet value better than a dealer of Jindal stainless as a result of our cost is a minimum of 5% low in comparison with other dealers and distributors of Jindal in India as we carry the material in massive quantities.

Alloy 304H is a modification of Alloy 304 by which the carbon content material is managed to a range of 0.04-0.10 to provide improved high temperature energy to parts uncovered to temperatures above 800°F. It is supplied utilizing solely two process- cold rolled in addition to sizzling rolled. Now, we’re talking about its thickness that is from 0.6 mm to eighty mm and the width or dimension is as per your wants. ASTM a240 SS 304 / 304l plates are also being provided with the customized selections. Thus now, any patron can get it as per their selection, need and price range from us. And the properties are the principle purpose that the SS 304L Sheet is utilized in different purposes within the industries. Some of the industries which are there with the sheet and plate are petrochemical, pharmaceutical, oil and gas, pulp and paper, development, railways, food processing, and others.
The low carbon version, 304L, could also be required for full corrosion resistance when thicker sections are welded. The 304H version has a assured minimum carbon content material, which ensures good power at high temperatures. ASTM A240 metal plate covers Austenitic Steels, Ferritic steels and Martensitic Steels. With the properties that the SS 304L Sheet holds, they’re transferring through totally different high quality testing. So, a few of the tests that are performed are hardness, hydrostatic, ultrasonic, micro, macro, constructive materials identification, and intergranular corrosion resistance.

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 the way in which that the sheet and plate are developed with the help of the alloying steel grades. The corrosion resistance of stainless-steel mainly is dependent upon its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the internal structure major position is chromium . Chromium has high chemical stability and might kind a passivation movie on the steel floor to isolate the steel from the outside. To protect the steel plate from oxidation, and improve the corrosion resistance of the metal plate. The Alloys 304, 304L, and 304H austenitic stainless steels provide helpful resistance to corrosion on a variety of moderately oxidizing to moderately reducing environments. The alloys are used widely in gear and utensils for processing and handling of meals, beverages, and dairy products. Heat exchangers, piping, tanks, and different process equipment in contact with fresh water also utilize these alloys.
- The chromium content promotes the material’s appreciable resistance to the effects of corrosion and oxidation.
- One of essentially the most versatile and generally used stainless steels in the marketplace, Grade 304 chrome steel is probably the most normal used alloy of this type.
- Essentially, Grade 304 is an austenitic chromium alloy which is also called an “18/8” stainless because the make-up of the metal is 18% chromium and 8% nickel.
- For chrome steel sections which are welded heavily, publish-weld annealing could also be essential to provide maximum corrosive resistance.
- The chrome steel alloy resists most oxidizing acids and can withstand strange rusting though this does not imply that the steel is not going to tarnish over time.
Alloy 304 is the usual alloy since AOD know-how has made lower carbon ranges more simply attainable and economical. Alloy 304L is used for welded products A240-304 stainless steel plates which might be uncovered to circumstances which might trigger intergranular corrosion in service.
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.
It is essential to understand the mechanical properties of 304 and 304L stainless steel plate, ASTM A240. 304 stainless-steel plate has a minimum tensile energy of 75 ksi and a minimal yield strength at 0.2% of 30 ksi. This type of chrome steel plate has a most Brinell hardness of 201 and a Rockwell B hardness of ninety two. 304L stainless steel plate has a minimal tensile energy of 70 ksi and a yield strength at 0.2% of 25 ksi. This chrome steel plate additionally has an elongation of 40%, a most hardness of 201 on the Brinell scale and a hardness of 92 on the Rockwell B scale. It is an austenitic, corrosion resistant metal with glorious power, toughness, fabrication traits and weldability.
