aisi 306 stainless steel
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.
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.
ss 316 and 304
ASTM A240 specification covers chrome steel plates, sheets and strips for stress vessels and basic purposes. This specification covers chemical composition and mechanical properties for numerous grades of ferritic, austenitic, martensitic, duplex, tremendous duplex and excessive moly chrome steel alloys. 304 and 304L stainless-steel plates are part of the austenitic family of stainless-steel and they are one of the most versatile and broadly used kinds of stainless plate. They are a relatively low cost stainless product and used in quite a lot of purposes. 304 grades have glorious low temperature properties and reply well to hardening by chilly working. 304 stainless steel plate grades have good welding traits and publish weld annealing isn’t usually required to revive performance. 304 SS plates have excellent corrosion resistance in a wide range of totally different media.
For austenitic stainless steels as a bunch, the fatigue strength is typically about 35 % of the tensile power. Substantial variability in service outcomes is experienced since extra variables similar to corrosive conditions, form of stress and imply value, floor roughness, and different elements have an effect on fatigue properties. For this reason, no definitive endurance limit values may be given that are representative of all working situations. It is the popular steel for use in marine environments due to its higher resistance to pitting corrosion than other grades of metal. The fact that it is negligibly responsive to magnetic fields means that it may be used in purposes the place a non-magnetic metal is required.
- Essentially, Grade 304 is an austenitic chromium alloy which is also called an “18/8” stainless because the make-up of the metal is eighteen% chromium and 8% nickel.
- 304 SS plates have glorious corrosion resistance in a wide range of totally different media.
- 304 stainless steel plate grades have good welding characteristics and publish weld annealing is not usually required to restore performance.
- 304 grades have excellent low temperature properties and reply properly to hardening by cold working.
Alloys 316, 316L, and 317L are extra resistant to atmospheric and other delicate kinds of corrosion than the 18-8 stainless steels. In basic, media that do not corrode 18-eight stainless steels will not attack these molybdenum-containing grades. One identified exception is extremely oxidizing acids such as nitric acid to which the molybdenum-bearing stainless steels are less resistant. ANSON can supply ASTM A204 metal plates from inventory or from reputed metal mills. We additionally supply metal fabrication service the place metal plates can go through processings like chopping , drilling, welding, milling, machining as you require. Our metal mills have fabricating workers which have 5-10 years of working expertise. If you are interested in shopping for ASTM A204 metal plate merchandise, contact us now for the newest price or examine the following table for equal metal grade of ASTM A204.
Typical specs for 304 and 304L ss plates are ASTM A-240, ASME SA -240 and A666. One of the most versatile and commonly used stainless steels on the market, Grade 304 stainless-steel is probably the most standard 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 steel is eighteen% chromium and eight% nickel. The chromium content material promotes the fabric’s considerable resistance to the consequences of corrosion and oxidation.

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.

In addition to molybdenum, 316 additionally incorporates a number of other parts in various concentrations. Like other grades of chrome steel, marine grade stainless-steel is a relatively poor conductor of each A240-304 stainless steel plates heat and of electrical energy when compared to metals and other conductive supplies. Representative Charpy V-notch influence information for annealed Type 316 at room temperature are proven below.
The stainless-steel alloy resists most oxidizing acids and will withstand odd rusting although this does not mean that the steel is not going to tarnish over time. For stainless steel sections that are welded heavily, publish-weld annealing may be essential to offer most corrosive resistance. Both grades are austenitic stainless-steel which is one of the most widely used and versatile type of steel. As 304/304L stainless-steel plates & sheets have glorious corrosion resistance, 316/316L plates have higher nickel content than 304 and 304L SS sheets giving them even higher corrosion resistance particularly in marine purposes. ASTM A Sheets is among the most versatile and commonly used chrome steel grades available in the market.
304 metal
316 Stainless Steel is more corrosion resistant than grade 304 and is suitable for marine and coastal functions. The corrosion resistance of chrome steel plates depends mainly on its alloy composition (chromium, nickel, titanium, silicon, aluminum, manganese, and so on.) and the internal structure, and the main position is chromium. Chromium has excessive chemical stability and may type a passivation film on the metal surface to isolate the metallic from the skin, defend the steel plate from oxidation, and enhance the corrosion resistance of the metal plate. The chrome steel sheet has the ability to face up to basic corrosion just like the unstable nichrome 304.

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.
