ASTM A376 TP304N Stainless Steel Tube For High-Temperature Power Plant Components
Specifications
ASTM A376 TP304N is a specification for seamless austenitic steel tubes designed for high-temperature service, where the "N" designation indicates the addition of Nitrogen (0.10-0.16%). This alloying element significantly increases the material's yield strength and provides improved resistance to pitting and crevice corrosion compared to standard TP304.
ASTM A376 TP304N tubing is applied in high-temperature and high-pressure systems where enhanced mechanical strength and improved corrosion resistance over standard Type 304 are key design considerations.
