Introduction
A low-carbon variant of TP304L (C ≤0.035%), designed to minimize carbide formation and enhance weldability under ASTM A269/270/213 standards.
Key Features
Reduced Intergranular Corrosion
Lower carbon content prevents chromium carbide precipitation, ideal for welded structures in corrosive environments (e.g., chlorides).
Improved Ductility
Retains toughness even at cryogenic temperatures (down to 0°C).
Applications
Pharmaceutical, semiconductor, and sanitary systems requiring high-purity surfaces (e.g., electropolished tubes).
