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.
For these purposes it is common to use particular “304DDQ” variants. It can be famous that the 304 SS Flat Bar has an excellent performance in a wide range of atmospheric environments in addition to many corrosive media. Bars manufactured from grade 304 stainless steel are thought-about to be proof against potable water that contains as much as about 200 mg/L chlorides at ambient temperatures. the corrosion resistant motion A240-304 stainless steel plates of the 304 SS Round Bar reduces to about 150 mg/L at a slightly larger temperature of 60 °C. Fabrication strategies involving chilly working could require an intermediate annealing stage to alleviate work hardening and avoid tearing or cracking. At the completion of fabrication a full annealing operation should be employed to reduce internal stresses and optimise corrosion resistance.

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.
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.

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.

The standard for ASTM A276 specification covers both, scorching -finished or chilly-completed chrome steel bars with the exception of re-forged bars. The ASTM A276 Type 304 is among the mostly used and versatile grades of stainless steel. Fusion welding performance for type 304 stainless steel is excellent both with and with out fillers. Recommended filler rods and electrodes for stainless-steel 304 is grade 308 stainless-steel.
The Stainless Steel 304 Round Bar has good oxidation resistance in intermittent service at a temperature vary of 870 °C and in steady service to a temperature of 925 °C. 304 and 304/L (UNS S30400 & UNS S30403) are austenitic alloys of chrome steel bars. These alloys are the most acquainted and most incessantly used alloys in the chrome steel family.
