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.
304 and 304L stainless steel plate can also be used as a development materials in specifically massive buildings and can also A240-304 stainless steel plates be utilized within the dyeing, textile, and paper industry. SS 304L Foil is a really skinny sheet of Stainless Steel that has been hammered or rolled flat.
The surest warmth therapy to accomplish both requirements is the solution anneal which is conducted in the 1850°F to 2050°F range (1010°C to 1121°C). Cooling from the anneal temperature should be at sufficiently high charges by way of °F (816°C – 427°C) to keep away from reprecipitation of chromium carbides. Alloy 309 (23% Cr 13.5% Ni) or nickel-base filler metals are utilized in becoming a member of the 18-eight austenitic alloys to carbon metal. A temperature gradient is produced within the materials being welded which ranges from above the melting temperature within the molten pool to ambient temperature at far from the weld. The greater the carbon level of the material being welded, the larger the probability that the welding thermal cycle will outcome within the chromium carbide precipitation which is detrimental to corrosion resistance. To provide materials at the most effective stage of corrosion resistance, low carbon materials ought to be used for materials put in service in the welded situation.
Alternately, full annealing dissolves the chromium carbide and restores a high degree of corrosion resistance to the usual carbon content material materials. Minimum mechanical properties for annealed Alloys 304 and 304L austenitic chrome steel plate as required by ASTM specifications A240 and ASME specification SA-240 are proven below. Alloys 304, 304L, and 304H are additionally resistant to moderately aggressive organic acids corresponding to acetic and reducing acids similar to phosphoric. The 9 to eleven percent of nickel contained by these 18-8 alloys assists in offering resistance to reasonably decreasing environments.
This sheet is available in numerous types like shim sheet, perforated sheet, chequered plate and so forth. Exposure of the 18-eight austenitic stainless steels to temperatures within the 800°F to 1500°F (427°C to 816°C) range could trigger precipitation of chromium carbides in grain boundaries. Such steels are “sensitized” and subject to intergranular corrosion when exposed to aggressive environments. The carbon content material of Alloy 304 could enable sensitization to occur from thermal conditions experienced by autogenous welds and warmth-affected zones of welds. For this purpose, the low carbon Alloy 304L is most well-liked for functions in which the fabric is put into service within the as-welded condition. In some cases, the low carbon Alloy 304L may present a decrease corrosion rate than the upper carbon Alloy 304.
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.
Below are some common product standards and tests.

Heat exchangers, piping, tanks, and other course of tools in contact with contemporary water also make the most of these alloys. Each alloy represents a superb mixture of corrosion resistance and fabricability. This mixture of properties is the rationale for the extensive use of these alloys which represent almost one half of the whole U.S. chrome steel manufacturing. The 18-eight stainless steels, principally Alloys 304, 304L, and 304H, can be found in a wide range of product forms including sheet, strip, and plate. The alloys are covered by quite a lot of specs and codes relating to, or regulating, building or use of equipment manufactured from these alloys for specific conditions. Food and beverage, sanitary, cryogenic, and strain-containing functions are examples.

In order to determine whether a material is 304 stainless steel, it must meet the requirements of each element in the product standard. As long as one does not meet the requirements, it cannot be called 304 stainless steel.
