Product introduction

904L stainless steel is a non-stabilized austenitic stainless steel with low carbon content. This high alloy stainless steel is added with copper to improve its resistance to strong reducing acids, such as sulphuric acid. The steel is also resistant to stress corrosion cracking and crevice corrosion. 904L is non-magnetic, and offers excellent formability, toughness and weldability.
904L contains high amounts of expensive ingredients, such as molybdenum and nickel. Today, most of the applications that employ grade 904L are replaced by low-cost duplex stainless steel 2205.

Possible Alternative Grades

Grade Reasons for choosing grade 904L
316L A lower cost alternative, but with much lower corrosion resistance.
6Mo A higher resistance to pitting and crevice corrosion is needed.
2205 A very similar corrosion resistance, with the 2205 having higher mechanical strength, and at a lower cost to 904L. (2205 not suitable for temperatures above 300°C.)
Super duplex Higher corrosion resistance is needed, together with a higher strength than 904L.
