As a draw again, 304H has lowered corrosion resistance in moist circumstances at lower temperatures. Nickel helps increase the corrosion resistance of the metal and also makes it austenitic. In reality, the related product standards have very clear regulations on 304, and these product requirements have some variations for different shapes of stainless-steel. The Chemical Composition of ASTM A240 grade 304L is P Max 0.045, Mn Max 2, C Max 0.03, S Max 0.03, Cr 18 – 20, Si Max 1 and Ni eight – 12. It is feasible to weld 304L stainless-steel with out having any carbon precipitation issues. We have been dedicating ourselves to piping and pipeline engineering since the inception.
|Element||Type 304||Type 304L|
|Sulfur||0.030 Max||0.030 Max|
|Phosphorus||0.045 Max||0.045 Max|
|Silicon||0.75 Max||0.75 Max|
|Chromium||17.5 to 19.5||18.0 to 20.0|
|Nickel||8.0 to 10.5||8.0 to 12.0|
|Nitrogen||0.10 Max||0.10 Max|
The last thing when the merchandise is to be shipped to its consumers, it’s packed fastidiously using industry setup method. The ASTM A240 SS 304L sheets are packed utilizing wood packing containers, picket crates, carton packing containers and so forth to supply full security to the product when internationally shipped. The Main difference between these two stainless steel plates is the quantity of carbon contained within every metallic. 304 incorporates at most 0.08% carbon whereas 304 L contains at most zero.03% carbon.
Types 304 and 304L are weldable by most fusion or resistance welding techniques. If filler metal is required, Type 308 is normally used. Type 304L should be used in heavier sections to reduce the occurrence of carbide precipitation in the heat affected region adjacent to the weld pool
Types 304 and 304L provides corrosion resistance in a wide range of moderately oxidizing and reducing conditions, fresh water and non-marine applications.
