Overview

304LN is a low carbon, low nitrogen stainless steel with good high temperature strength and corrosion resistance, which is often used in high temperature equipment and pipelines. 304LN has good low temperature toughness and low temperature corrosion resistance in low temperature applications such as refrigeration equipment and low temperature engineering.

Characteristic

1.Good corrosion resistance: 304LN stainless steel has excellent corrosion resistance, performs well in acidic and alkaline environments, and is suitable for manufacturing equipment and parts in chemical, Marine engineering, food processing and other fields.

2.Good machinability: 304LN stainless steel has good machinability, easy to work cold and hot, and can manufacture a variety of complex parts and equipment.

3.Good weldability: 304LN stainless steel has good weldability and can be welded by TIG, MIG and other methods.

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.
