Alloy 2304 Stainless Steel
WLD Steel is a leading manufacturer, supplier and exporter of the duplex stainless steel 2304 available in a number of different sizes and forms including pipe, tube, sheet, plate, bar, rod and other shapes like angle, channel, circle, cut piece and so on.
Alloy 2304 is a type of low alloy molybdenum-free duplex stainless steel. It has a structure that is a balance of Ferritic and Austenitic and has good resistance to pitting and crevice corrosion, the duplex stainless steel grade 2304 is often used as a replacement material for Alloys 304L and 316L but twice yield strength of 304L/316L, widely used in boilers and pressure vessels, chemical plants and oil refinery pipelines, amine recovery equipment, hydrocarbon fermentation equipment, preheaters for the pulp and paper industry, etc.
