Type 304 and 304L Stainless Steel Explained - The BalanceType 304L stainless steel is an extra-low carbon version of the 304 steel alloy. The lower carbon content in 304L minimizes deleterious carbide precipitation as a result of welding. 304L can, therefore, be used "as welded" in severe corrosion environments and it eliminates the need for annealing.

What’s the difference between 304 and 316 stainless steel ...What is Type 304 stainless steel and what’s it used for? Type 304, with its chromium-nickel content and low carbon, is the most versatile and widely used of the austenitic stainless steels. Its alloys are all modifications of the 18% chromium, 8% nickel austenitic alloy. Type 304 proves to be resistant to oxidation, corrosion, and durability.[PDF]

What forms of corrosion can occur in stainless steels?General corrosion - Normally, stainless steel does not corrode uniformly as do ordinary carbon and alloy steels. However, with some chemicals, notably acids, the passive layer may be attacked uniformly depending on concentration and temperature and the metal loss is distributed over the entire surface of the steel.
Galvanic Series - CorrosionA galvanic series has been drawn up for metals and alloys in seawater, which shows their relative nobility. The series is based on corrosion potential measurements in seawater. The series is based on corrosion potential measurements in seawater.
Stainless Steel 304 and 316 – The DifferencesThe 304 stainless steel does have a weakness, i.e., it is likely to corrode from chloride solutions, or from saline environments in coastal areas. Chloride ions may cause areas of corrosion, called ‘pitting’ which can pass under the protective chromium barriers to attack internal structures.
