ASTM A376 TP304LN Stainless Steel Tube For Power Generation Systems
Specifications
ASTM A376 covers seamless austenitic steel pipe intended for high-temperature central-station service. ASTM a376 grades covered are five H grades and two nitrogen grades.ASTM A376 Pipe may be either hot finished or cold finished, with a suitable finishing treatment. All ASTM A376 pipes shall be furnished in the heat-treated condition unless the order specifically states that no final heat treatment shall be applied. Tensile tests, hydrostatic test, nondestructive electric tests, ultrasonic tests, eddy-current tests, tension tests, and flattening tests shall be made to conform to the requirements specified.
ASTM A376 TP304LN is a specification for seamless austenitic steel tubes where "LN" stands for Low Nitrogen. This grade has a controlled low carbon content (0.030% max) for improved corrosion resistance and an added nitrogen content (0.10-0.16%) to compensate for strength. This combination makes it suitable for specific demanding environments.

ASTM A376 TP304LN Stainless Steel Tube Application
ASTM A376 TP304LN tubing is specified for applications requiring a combination of good corrosion resistance, particularly in welded structures, and higher mechanical strength than standard TP304L, typically in corrosive and high-purity industrial systems.
