ASTM A269 TP 304/304L WELDED TUBES

ASTM A269 TP 304 / 304L Welded Tubes

ASTM A269 TP 304 / 304L Welded Tubes are premium quality austenitic stainless steel tubes designed for general corrosion-resistant and low to moderate temperature service applications. These tubes are manufactured using high-grade 304 and 304L stainless steel and are widely known for their excellent corrosion resistance, durability, and fabrication properties.

TP 304 is the most commonly used stainless steel grade, offering excellent resistance to oxidation and corrosion in a wide range of environments. TP 304L is the low-carbon version of 304, which minimizes the risk of intergranular corrosion after welding. ASTM A269 TP 304 / 304L Welded Tubes are commonly used in food processing, pharmaceuticals, heat exchangers, instrumentation, and structural applications.
