Frequently Asked Questions
What is the carbon content of TP304L under ASTM A269/270/213?
TP304L is a low-carbon variant of stainless steel with a carbon content restricted to a maximum of 0.035% (C ≤ 0.035%) to minimize carbide precipitation during welding.
What are the primary applications for ASTM A269/270/213 TP304L tubes?
They are widely used in sanitary, pharmaceutical, and semiconductor systems that require high-purity surfaces, as well as in heat exchangers, boilers, energy sectors, and food and dairy plants.
Why is a lower carbon content beneficial for welded structures?
The reduced carbon content prevents chromium carbide precipitation at the grain boundaries, which significantly improves weldability and reduces the risk of intergranular corrosion in corrosive environments.
What delivery conditions and finishes are available for these stainless steel pipes?
They can be delivered as Cold Drawn, Annealed and Pickled, Polished, Bright Annealed, Sand blasted, or Shot Blasted.
What quality inspections are conducted on the TP304L pipes?
The pipes undergo 100% PMI testing, are certified with an EN10204.3.1B Mill Test Certificate, and are compatible with third-party inspections.
Can sizes and specifications beyond the standard range be customized?
Yes, custom sizes, wall thicknesses, and special specifications outside the standard tables are available upon request.
