Alpha Overseas(AOS) is one of the eminent manufacturers that offer Stainless Steel 904L Pipes, which is a non-stabilized austenitic stainless steel with low carbon content. Stainless Steel 904L Tubes is a low carbon high alloy austenitic stainless steel which is widely used in applications where the corrosion properties of SS 316L and SS 317L are not adequate. SS 904L Tubes is a super-austenitic stainless steel designed for corrosion and pitting resistance in a wide range of process environments. Stainless Steel 904L Seamless Pipes is a fully austenitic low-carbon variety of stainless steel with additives of molybdenum and copper. Stainless Steel 904L Welded Pipes is an austenitic stainless steel designed for moderate to high corrosion resistance. Stainless Steel 904L EFW Pipes has greater amounts of chromium and nickel than the 316L grade. Stainless Steel 904L ERW Pipes is intended for use under severe corrosion conditions within the process industry. Alloy 904L Seamless Tubes is an austenitic stainless steel intended for use under severe corrosion conditions, with a very good resistance to attacks in acidic environment, as phosphoric, acetic and sulphuric acid.
