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

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.

The Alloys 304, 304L, and 304H austenitic stainless steels provide helpful resistance to corrosion on a variety of moderately oxidizing to reasonably reducing environments. The alloys are used broadly in tools and utensils for processing and handling of food, drinks, and dairy products. Heat exchangers, piping, tanks, and other process gear in touch with contemporary water additionally utilize these alloys. Type 304 and Type 304L have very comparable chemical and mechanical properties and are often included on a single materials test certificate when the precise properties of a stainless steel plate meet the standards of both types. Type 304L is a variation of Type 304 and has a decrease carbon content material which improves weldability and lowers the danger of decreased corrosion resistance around the weld. Type 304L additionally has a barely decrease yield and tensile strength than Type 304.
This pipe belongs to the 300 series of pipes, specifically grade 304H. Grade 304H, has the next carbon content material and has some utility at elevated temperatures, as does stabilised grade 304Ti.

The carbon content material of Alloy 304 may enable sensitization to happen from thermal conditions skilled by autogenous welds and heat-affected zones of welds. For this cause, the low carbon Alloy 304L is most popular for purposes in which the fabric is put into service in the as-welded situation. Low carbon content material extends the time necessary to precipitate a harmful level of chromium carbides but does not remove the precipitation response for materials held for long times within the precipitation temperature vary. In some cases, the low carbon Alloy 304L may show a lower corrosion rate than the higher carbon Alloy 304. The data for formic acid, sulfamic acid, and sodium hydroxide illustrate this. Otherwise, the Alloys 304, 304L, and 304H may be thought of to perform equally in most corrosive environments.
