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.

It will not work very correctly in tremendously reducing environment similar to for instance the ones comprising lipoic acid & chlorides. However, it really works very successfully in water service having elevated heights of chlorides. And also at chloride levels, the standard might be vulnerable that the carbon material that’s increased produces electrical .

Beside this, in this materials, you will find the use of the carbon content that’s 0.08%. You will generally discover this grade of the metal within the cooking tools and pans. It additionally has the most effective corrosion resistance capability; with that, it also has the excessive ease of the fabrication property. 304 chrome steel is a nationally recognized food grade stainless steel. 304 is a sort of common stainless-steel, which is broadly used to make gear and components with good comprehensive performance . In order to take care of the inherent corrosion resistance of stainless steel, the steel should contain greater than 18% chromium and more than eight% nickel.
