ALLOY 904L PIPES

Listing ID #1841219

Alloy 904L is a high-combination austenitic stainless steel with low carbon content. The evaluation is proposed for utilization under extreme destructive conditions. It has been application demonstrated over numerous years and was initially created to oppose consumption in weaken sulphuric corrosive. It is institutionalized and affirmed for weight vessel use in a few nations. Basically, Alloy 904L is completely austenitic and is less delicate to precipitation ferrite and sigma stages than customary austenitic evaluations with high molybdenum content. Distinctively, because of the mix of generally high substance of chromium, nickel, molybdenum and copper 904L has great imperviousness to general erosion, especially in sulphuric and phosphoric conditions.
