What is ASTM A269 TP304L bright annealed pipe?
304L Stainless Steel BA Tube is a low carbon austenitic stainless steel tube produced according to ASTM A269 standard with a bright annealed (BA) surface finish, which provides a clean, smooth and reflective surface, making it ideal for high purity and corrosion sensitive applications.
ASTM A269 TP304L Stainless steel bright tube
ASTM TP304L bright annealed pipe is available in both seamless and welded forms, featuring a smooth inner surface that enhances corrosion resistance and reduces contamination risk. It complies with ASTM A269 standards for seamless and welded austenitic stainless steel tubing and is commonly used in general service and mechanical applications, such as food and beverage processing, medical and pharmaceutical systems, chemical delivery lines, semiconductors, and instrumentation tubing.
The TP304L annealed pipes we supply typically range in outside diameter from 1/4 inch to 2 inches (6.35 mm to 50.8 mm), with various wall thicknesses and custom lengths available upon request.
