304L tees, constructed from low-carbon 304 stainless steel (UNS S30403), excel in applications where welded joints must resist intergranular corrosion, making them ideal for high-purity and corrosive environments. The reduced carbon content (<0.03%) eliminates carbide precipitation during welding, ensuring continuous corrosion resistance in sensitized conditions. Newstar Hardware’s 304L tees are available in equal and reducing types, compliant with ASME B16.9 and MSS SP-43, offering sizes from 1/2" to 24" (DN15 to DN600) and pressure ratings up to 2500#. This alloy’s chromium-nickel composition provides excellent resistance to mild acids, alkalis, and chloride solutions, suitable for pharmaceutical manufacturing, food and beverage processing, and pure water systems. The tees’ smooth internal surfaces—achievable through electropolishing—minimize product adhesion and facilitate cleaning in hygienic applications. With a tensile strength of 485MPa and yield strength of 170MPa, these tees balance mechanical robustness with formability, ensuring leak-free branch connections in systems where corrosion risks and contamination must be strictly controlled. Rigorous testing for intergranular corrosion guarantees reliability in critical service.
