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.
Our water jet slicing capabilities for 304 stainless-steel plates are as much as 6” x a hundred and twenty x 144. Grade ASTM A Stainless Steel is the usual “18/8” stainless; it is the most versatile and most generally used chrome steel, available in a wider range of merchandise, varieties and finishes than some other. ASTM A240 Grade 304 is instantly brake or roll shaped into a wide range of components for applications within the industrial, architectural, and transportation fields. Surface remedy and upkeep are required to protect iron from its tendency to rust. From the need to forestall this loss to rust came the developments of rust-free steel and chrome steel. To prevent rust, at least 10.5 p.c chromium is used to type a nice oxidation movie on the floor of the metal.

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 stainless-steel alloy resists most oxidizing acids and can withstand strange rusting although this doesn’t imply that the metal won’t tarnish over time.
- The chromium content promotes the fabric’s appreciable resistance to the results of corrosion and oxidation.
- For stainless steel sections that are welded heavily, publish-weld annealing may be needed to offer most corrosive resistance.
- The sheets are sturdy, delicate corrosion resistant and have functions in a variety of industries.
- The Stainless Steel 304 Sheet also has manganese, carbon, silicon, sulfur, nitrogen and phosphorus in the composition.

The fatigue energy for austenitic stainless steels, as a group, is typically about 35 % of the tensile energy. Substantial variability in service outcomes is experienced since additional variables influence fatigue strength.

The 18-8 stainless steels, principally Alloys 304, 304L, and 304H, can be found in a variety of product types including sheet, strip, and plate. The alloys are covered by quite a lot of specs and codes regarding, or regulating, construction or use of equipment manufactured from these alloys for particular conditions. Food and beverage, sanitary, cryogenic, and stress-containing functions are examples. One of probably the most versatile and generally used stainless steels on the market, Grade 304 chrome steel is essentially the most normal used alloy of this kind. Essentially, Grade 304 is an austenitic chromium alloy which is also known as an “18/eight” stainless because the make-up of the metal is 18% chromium and 8% nickel. The chromium content promotes the material’s appreciable resistance to the effects of corrosion and oxidation.
The shoppers are ensured about the high quality of the sheet and plate with the exams performed. Greenline Pipe and Fitting is catering all of the rising demands of the clients for SS 304 Sheet. We are thought of because the outstanding producer and provider of the superior high quality of SS 304 Plate as well as a sheet.
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.

This stainless 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. A temperature gradient is produced in the materials being welded which ranges from above the melting temperature within the molten pool to ambient temperature at a long way from the weld. The greater the carbon stage of the material being welded, the greater the chance that the welding thermal cycle will result within the chromium carbide precipitation which is detrimental to corrosion resistance.
304 Stainless metal plate is among the most versatile stainless steel materials obtainable. Grades 304 and 304L stainless-steel plate is dominant in the manufacture of stainless A240-304 stainless steel plates steel fabrications. 304 chrome steel plate may be braked formed into quite a lot of elements for functions in the industrial, architectural, and transportation sectors.
Low carbon content material extends the time necessary to precipitate a harmful degree of chromium carbides however doesn’t get rid of the precipitation reaction for material held for long occasions within the precipitation temperature vary. publicity of the 18-8 austenitic stainless steels to temperatures within the 800°F to 1500°F (427°C to 816°C) range may trigger precipitation of chromium carbides in grain boundaries. Such steels are “sensitized” and topic to intergranular corrosion when exposed to aggressive environments. Type 304 and Type 304L have very related chemical and mechanical properties and are sometimes included on a single material test certificate when the actual properties of a stainless steel plate meet the criteria of both types. Type 304L is a variation of Type 304 and has a decrease carbon content material which improves weldability and lowers the risk of reduced corrosion resistance across the weld. Type 304L also has a slightly decrease yield and tensile energy than Type 304. There are completely different grades and floor finishes of chrome steel to go well with the surroundings the alloy must endure.

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.

There are over a hundred and fifty grades of stainless-steel, of which fifteen are the most used. Farmer’s Copper Ltd. is a number one 304L Stainless Steel provider, maintaining an inventory of Type 304/304L chrome steel in spherical, square, hex, angles, flat bar, sheet, plate, pipe and tube. 304 is an austenitic chrome steel with non-magnetic properties within the annealed condition that offers good corrosion resistance to each chemical and atmospheric exposures, with a high resistance to oxidation. The corrosion resistance of chrome steel primarily depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, and so forth.) and the inner construction main position is chromium . Chromium has high chemical stability and can type a passivation movie on the steel surface to isolate the metal from the skin. To defend the steel plate from oxidation, and improve the corrosion resistance of the metal plate. 304 and 304L ASTM A240 stainless steel plate is a normal 18-eight material – that means it accommodates 18% chromium and eight% nickel.
