What is astm a240 specification other grade?
- 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).
- 301 stainless steel presents obvious work hardening phenomenon during deformation, which is used in various occasions requiring higher strength.
- 302 stainless steel is essentially a variety of 304 stainless steel with higher carbon content, which can obtain higher strength by cold rolling.
- 302B is a kind of stainless steel with high silicon content, which has high oxidation resistance at high temperature.
- 303se and 303se are free cutting stainless steels containing sulfur and selenium respectively, which are mainly used in the occasions requiring easy cutting and high surface finish. 303se stainless steel is also used to make machine parts requiring hot upsetting because it has good hot workability under such conditions.
- 304L is a variant of 304 stainless steel with low carbon content, which is used for welding. The lower carbon content makes the carbides precipitated in the heat affected zone near the weld to a minimum, and the precipitation of carbides may cause intergranular corrosion (welding corrosion) of stainless steel in some environments.
- 304n is a kind of stainless-steel containing nitrogen. The purpose of adding nitrogen is to improve the strength of steel.
- 305 and 384 stainless steels contain high nickel, and their work hardening rate is low, so they are suitable for various occasions with high requirements for cold formability.
- 308 stainless steel is used for welding rod.
- The contents of Ni and Cr in 309, 310, 314 and 330 stainless steels are relatively high in order to improve the oxidation resistance and creep strength of the steels at high temperature. However, 309S and 310S are variants of 309 and 310 stainless steels, but the difference is that the carbon content is low, so as to minimize the carbide precipitated near the weld. 330 stainless steel has high carburizing resistance and thermal shock resistance
- Type 316 and 317 stainless steels contain molybdenum, so their pitting corrosion resistance in marine and chemical industry environments is much better than that of 304 stainless steel. Among them, type 316 stainless steel includes low carbon stainless steel 316L and high strength stainless steel containing nitrogen.
- 316N and 316F, a free cutting stainless steel with high sulfur content.
- 321, 347 and 348 are stainless steels stabilized with titanium, niobium plus tantalum and niobium respectively. They are suitable for welding at high temperature. 348 is a kind of stainless steel which is suitable for nuclear power industry.
- The forging property of 304L stainless steel is poor and the deformation is difficult.

ASTM A240 304L stainless steel plate rod Manufacturer
However, this could compromise the corrosion resistance of the steel, making it more prone to corrosion injury from exposure to moisture. 304/304L chrome steel has excellent corrosion resistance at regular temperatures in ordinary atmospheric situations withstanding some pure acids, which is why this grade is used frequently in the meals & drink processing trade. In more corrosive environments such as a marine environment, or an environment where greater chloride and chlorine content material is an element, the next spec grade such as 316/316L or a Duplex grade could also be a greater possibility. ANSON can supply ASTM A204 metal plates from stock or from reputed steel mills.

Which is better 18 10 or 18 8 stainless steel?
Keep in mind the difference between 18/10 stainless steel and 18/8 stainless is only 2%. While 18/10 stainless steel will be slightly better at conducting heat you may want to save money by choosing an 18/8 stainless steel product. A perfect example of 18/8 stainless steel is an Induction Ready Wok from Adcraft.
It is the most versatile and most widely used stainless steel obtainable, although a wide range of alternate options are available; and has excellent forming and welding characteristics. The balanced austenitic construction of Grade 304 enables it to be severely deep drawn with A240 SS304L steel plate MILL out intermediate annealing. This means that this grade metal is dominant in the manufacture of drawn stainless components corresponding to sinks, hollow-ware and saucepans. For these functions, it is not uncommon to use special “304DDQ” variants.

Consequently, the flange is open to welding and forming in as a lot as possible methods and methods, even in extremely corrosive environment. Grade SS 304L is also referred to as 18-eight metal, mainly as a result of composition of 18% Chromium and eight% Nickel, answerable for inhibiting corrosion caused because of acids within the meals and beverage industry.
The elements which have a big impression are chromium, molybdenum and nitrogen. In most cases the corrosion resistance of Alloy 316H will be comparable to Alloy 316/316 L and could have superior corrosion resistance to Alloy 304/304L. Process environments that don’t attack Alloy 304/304L is not going to attack this grade.
There can also be a slight distinction within the nickel levels in the stainless-steel plate. 304 chrome steel plate can contain up to 10.5% nickel whereas 304L can include up to 12% nitrogen. 304 Stainless Steel Plate is likely one of the most versatile and generally used stainless steels in the marketplace, Grade 304 stainless-steel is essentially the most normal used alloy of this sort. Essentially, Grade 304 is an austenitic chromium alloy which is also known as an “18/8” stainless as the make-up of the steel is 18% chromium and eight% nickel. exposure 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 subject to intergranular corrosion when exposed to aggressive environments. The carbon content of Alloy 304 could enable sensitization to happen from thermal circumstances experienced by autogenous welds and warmth-affected zones of welds.
