Gangsteel produce ASTM A240 304 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 Sheet, is the most popular and economical of the stainless . 304 Stainless Sheet presents good corrosion to many chemical corrodents as well as industrial atmospheres and marine environments. 304 Stainless Sheet might turn into slightly magnetic when labored and isn’t heat treatable. Grade 316 has glorious corrosion resistance when uncovered to a variety of corrosive environments and media.

Cooling of those Stainless 316 plates should be sufficiently fast from 1500°F to 800°F (816 °C to 427°C) range to keep away from reprecipitation of chromium carbides and supply optimum corrosion resistance. In every case, the metallic ought to be cooled from the annealing temperature to black warmth in lower than three minutes. Exposure of the 18-eight austenitic stainless steels to temperatures within the 800°F to 1500°F (427°C to 816°C) vary might cause precipitation of chromium carbides in grain boundaries. Such steels are “sensitized” and subject to intergranular corrosion when exposed to aggressive environments. The carbon content of 304 may permit sensitization to happen from thermal conditions experienced by autogenous welds and warmth-affected zones of welds.

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.

  • The sheets are robust, gentle corrosion resistant and have purposes in a variety of industries.
  • The materials is strong and has 205MPa minimum yield power and 515MPa minimum tensile power normally.
  • The Stainless Steel 304 Sheet additionally has manganese, carbon, silicon, sulfur, nitrogen and phosphorus in the composition.
  • 316/316L plate is a good possibility for marine applications as a result of a good atmospheric corrosion resistance.
  • 316 / 316L chrome steel plates are part of the austenitic family of chrome steel and is essentially the most widely used kinds of stainless plate.

Cooling from the anneal temperature should be at sufficiently excessive rates by way of °F (816°C – 427°C) to avoid reprecipitation of chromium carbides. One of probably the most versatile and commonly used stainless steels on the market, Grade 304 stainless-steel is the most standard used alloy of this type. Essentially, Grade 304 is an austenitic chromium alloy which is also referred to as an “18/eight” stainless as the make-up of the steel is 18% chromium and 8% nickel. The time period ‘corrosion resistant metal’ is used when the alloy has less than the 12% minimum of chromium, for in the aviation industry. There are different grades and floor finishes of chrome steel, depending on the place it is going to be used.

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 3CR12 with black end has a great corrosion resistance and low friction and, hence, it’s suitable for different put on functions. These properties make grade 316 stainless steel sheet and plate an ideal selection for medical applications, marine environments, refining or chemical processing, and other highly corrosive environments. Grade 304 stainless steel sheet and plate have a excessive nickel and chromium content material, which supplies glorious corrosion resistance. Stainless steel 304 can A240-304 stainless steel plates be nonmagnetic, has excellent formability, and is simple to fabricate, making it a wonderful possibility for a broad range of light-duty and general-purpose purposes. Additionally, grade 304-2b sheet isn’t magnetic within the annealed situation and can’t be hardened through heat therapy. Although both 304 and 304L stainless-steel plate have comparable chemical properties, there are a number of noticeable differences.

It is created through cold-rolling annealing and a pickled and pinch-move, or descaling. A 2b Mill finish is achieved by way of the addition of a light cold roll pass. This is the most utilized stainless-steel end on the earth and it is the typical end for a lot of grades together with 304 stainless-steel. This end is straightforward to keep up which makes it in style for every little thing from bakeware and flatware to plumbing fixtures, wheel covers, and lots of industrial applications such as solar panels and other gear.

It can also be extremely proof against chloride assault – both pitting/crevice corrosion and stress corrosion cracking.904Lis non-magnetic in all circumstances and has glorious weld ability and type capacity. The authenticate construction additionally gives this grade excellent toughness, even all the way down to cryogenic temperatures.

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 also has an elongation of 40%, a most hardness of 201 on the Brinell scale and a hardness of 92 on the Rockwell B scale. Grade 3CR12 stainless steels exhibit scaling resistance between 600 and 750°C in the presence of air, and between 450 and 600°C under stress environments.

The excessive chromium content material of the alloy provides resistance to oxidizing solutions similar to nitric acid as much as 55% and as much as 176°F (80°C). It resists atmospheric corrosion, as well as, reasonably oxidizing and decreasing environments. However, because of its high carbon content material, Alloy 304/304H is subject to carbide precipitation in the warmth affected zone of welds. We have a good price coverage for all our customers with greatest supply schedule. We are supplying chrome steel plates as per varied worldwide requirements and specifications like ASTM, AISI, BS, DIN, JIS etc. All frequent scorching working processes may be performed on 316 stainless-steel. Post-work annealing is really helpful to ensure optimum corrosion resistance.
