Unimix Metal Corporation is a well-known manufacturer, exporter, and supplier of Stainless Steel 904L Flanges. These UNS N08904 Flanges are offered in a variety of diameters, wall thicknesses, and sizes at competitive prices. Grade 904L Flanges contain high levels of costly materials like molybdenum and nickel
.The austenitic structure also provides Werkstoff Nr. 1.4539 SS 904L Slip-On Flanges with excellent toughness, even at cryogenic temperatures.
We produce SS 904L Weld Neck Flanges designed to ensure that the channel’s separation perfectly matches the width of the Stainless Steel 904L Flanges. We use high-grade stainless steel to manufacture SS 904L Spectacle Blind Flanges, which is one of the rare stainless steels that offers complete resistance in dilute sulfuric acid environments across the full range of concentrations at temperatures up to 35°C (95°F).
