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 low-carbon 304L alloy when working under low-temperature annealing.

The low carbon version, 304L, may be required for full corrosion resistance when sections thicker than about 6mm are welded. The version with guaranteed excessive carbon, 304H, could also be required for elevated temperature service, corresponding to stress vessels. In most functions the steel is used the place its corrosion resistance gives long lasting look and service life. The ease of cleansing and of maintaining a hygienic floor on the metal make it wonderful for a lot of purposes. Diamond plate, also referred to as a chequered plate, thread plate and ground plate, is a type of steel designed with an everyday pattern of raised diamonds or lines on one facet, with the reverse side being featureless. SS 304H Diamond Plate and Stainless Steel Diamond Plate is in prepared inventory with Siddhagiri Metals and Tubes.
