Features:
Due to the high chromium content in steel, its anti-oxidation and anti-corrosion properties are better than low alloy steel, but the thermal strength properties of steel
Lower than 2.25Cr-1Mo steel. Poor welding performance.
Application:
High temperature sulfur corrosion, high temperature naphthenic acid corrosion.
Reheater tubes with wall temperature ≤630℃.
Related standards:
ASTM A213
ASTM A335
