It is essential to know the mechanical properties of 304 and 304L stainless-steel plate, ASTM A240. 304 stainless steel plate has a minimum strength of 75 ksi and a minimal yield power at 0.2% of 30 ksi. This sort of stainless-steel plate has a most Brinell hardness of 201 and a Rockwell B hardness of ninety two. 304L stainless-steel plate has a minimal tensile energy of 70 ksi and a yield power at 0.2% of 25 ksi. This stainless-steel plate also has an elongation of 40%, a maximum hardness of 201 on the Brinell scale and a hardness of ninety two on the Rockwell B scale. Although both 304 and 304L chrome steel plate have similar chemical properties, there are a few noticeable variations. To start, 304 stainless-steel plate is comprised of at most 0.08% carbon.

From a metallographic point of view, because stainless steel contains chromium, a very thin chromium film is formed on the surface. This film isolates the intruding oxygen from the steel for corrosion resistance.

In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 12% chromium
SS 304H Plate Equivalent grades









SS 304H



304, 304L, and 304H alloys are the most prone to stress corrosion cracking (SSC) among austenitic stainless steels because of their relatively low nickel content.
The conditions that cause stress corrosion cracking are: (1) the presence of halide ions (usually chloride), (2) residual tension, and (3) the temperature exceeds 120°F (49°C).
Cold deformation during alloy forming, stenting into tube sheet, welding operations, etc. can all cause stress.
Annealing and stress relief heat treatment after cold deformation can reduce stress, thus reducing the possibility of halide stress corrosion cracking.
In the environment that may cause intergranular corrosion, it is best to choose low-carbon 304L alloy when working under low-temperature annealing.

These pipes can also be used in some as-welded condition subsequently the stainless steel have to be so to retain the corrosion resistant property. Stock measurement objects are supplied at a lowered value per pound over processed supplies.

An assortment of facings, ring joint grooves, andconnections can be found in flange variations. In ASTM A240, type 316 and 316L is a chromium nickel austenitic metal, Element molybdenum addition can enhances corrosion resistance of chrome steel, which is the primary factor that 316/316l is more corrosion resistant than 304/304l.

One advantage of methods is that they are simply dismantled andassembled. One of the disadvantages is that they’re considerably costlier thanan equally rated butt-welded system, due to the big amount of steel thatgo into making up joints and flanges. Moreover, flanged fittings occupy far morespace than the butt-welded or screwed equivalents. Because of this higherweight load, a flanged system turns into far costlier to assist or hangfrom the present construction. Flanged steel fittings are used rather than cast iron where the system is subjectedto shock or high-temperature/ excessive-stress situations where the hazard of fireplace isprevalent, as a result of forged iron tends to c rack or rupture under certainstresses. A flange may be forged or forged onto the ends of the becoming or valve andbolted to a connecting flange which is screwed or welded onto the pipeline,thereby providing a good joint.
