ASTM A269/270/213 TP304L GRADE SS SMLS TUBE
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 Corrosio: 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)
