Description

What is 304L Stainless Steel ?

Stainless Steel 304L is a variant of 304 stainless steel with lower carbon content and is used where welding is required. The lower carbon content minimizes the precipitation of carbides in the heat-affected zone near the weld, and the precipitation of carbides may cause stainless steel to produce intergranular corrosion (welding erosion) in certain environments.

304L Stainless Steel Good For: 

-Same good general corrosion resistance as Grade 304.

- Low Carbon (generally 0.03% max) gives resistance to sensitization for use in temperature range 450-850°C and in heavy section welding (over about 5-10mm thick)

-Low carbon content also reduces work hardening rate slightly–improves ductility for cold forging, drawing etc.

304L Stainless Steel Not Good For:

-Lower hot strength than 304-design codes limit use to about 500°C  maximum. This limit also applies to nominal Grade 304 with less than 0.03% Carbon.

-Same local corrosion resistance as 304, so only moderate resistance to pitting and crevice corrosion in Chloride environments.

-Same poor resistance to stress corrosion cracking as 304. Use 439, 444 or 2205 instead.
