ASTM A403 WP304 SS Butt weld Pipe Fitting Tees
304 and 304L are austenitic alloys, which means that a nonmagnetic solid solution of ferric carbide or carbon in iron is used in giving this stainless steel its corrosion-resistant properties.
The high amounts of chromium and nickel give 304 stainless steel tee excellent corrosion resistance. Stainless steel bw fittings stains less easily than other iron-based metals, but it¡¯s not literally ¡°stainless¡±. Just like standard steel, stainless steel pipe fittings can get marked up by fingerprints and grease, discolor, and eventually rust. The difference is resilience. Stainless steel equal tee can withstand much more time and abuse before showing signs of wear. All steels have the same basic iron and carbon composition, but SS 304 Pipe Fittings also contains a healthy dose of chromium¡ªthe alloy that gives stainless steel its famous corrosion resistance. SS 304 Tube Fittings must contain at least 10.5 percent chromium. Depending on the grade, SS 304 Seamless & Welded Fittings may contain much higher chromium levels, and additional alloying ingredients like molybdenum, nickel, titanium, aluminum, copper, nitrogen, phosphorous or selenium.
