The Stainless Steel 904L tube fittings from Emilio Stainless are made from a super austenitic alloy that includes 19–23% chromium, 23–28% nickel, 4–5% molybdenum, and trace amounts of copper. This unique blend gives them outstanding resistance to sulfuric acid, pitting, and crevice corrosion. On the mechanical side, SS 904L boasts a tensile strength of about 490 MPa, a yield strength of 220 MPa, and an elongation of roughly 35%. Remarkably, this alloy maintains its strength and corrosion resistance even in highly aggressive environments. These characteristics make SS 904L tube fittings a go-to choice for industries that need durable, corrosion-resistant, and long-lasting tubing connections.
