ASTM A269/270/213 TP304L Seamless Stainless Steel Tube from China Suppliers - Fast Delivery from Factory
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).

Frequently Asked Questions
What is the difference between TP304 and TP304L stainless steel?
TP304L is a low-carbon variant of TP304. It contains a maximum of 0.035% carbon, which minimizes chromium carbide precipitation during welding, thereby reducing susceptibility to intergranular corrosion.
Which standards apply to these stainless steel tubes?
These low-carbon stainless steel tubes are designed, processed, and tested in accordance with ASTM A269, ASTM A270, and ASTM A213 standard specifications.
What are the primary applications of ASTM A269/270/213 TP304L tubes?
They are widely used in sanitary systems, pharmaceutical plants, semiconductor manufacturing, food and beverage processing, heat exchangers, boilers, and architectural structures.
What mechanical properties can be expected from ASTM A213 TP304L?
ASTM A213 TP304L specifies a minimum tensile strength of 485 MPa, a minimum yield strength of 170 MPa, a minimum elongation of 35%, and a maximum hardness of 90 HRB or 192 HBW.
How are the tubes prepared and packed for delivery?
Tubes can be delivered in cold drawn, annealed, pickled, bright annealed, polished, sand-blasted, or shot-blasted conditions. They are safely packed in wooden boxes, plywood cases, steel strip bundles, or as requested by the customer.
