304LN Stainless Pipe Chemical Composition
304LN is an austenitic alloy made up of chromium, nickel, manganese, silicon, phosphorus, sulfur and nitrogen. It has a low carbon content compared to other grades of stainless steel, which makes it ideal for use in cryogenic applications or for welding components exposed to corrosive environments.

Mechanical Properties Stainless Steel 304LN
The mechanical properties of grade 304LN are similar to those of other austenitic stainless steels like Type 316. Its tensile strength ranges between 485MPa (70ksi) and 650MPa (93ksi), while its yield strength can range anywhere between 175MPa (25ksi) and 345MPa (50ksi). Its elongation levels are usually around 40% when tested at room temperature but can go up if the testing environment is hot enough or if the part being tested has undergone heat treatment. Furthermore, its thermal expansion coefficient is 13 x 10-6/K which makes it suitable for use in high-temperature applications such as boilers or exhaust systems.
