What braze alloy would be appropriate for brazing 300 series steel that will be subjected to contact with water?
When brazing stainless steels that will be exposed to water, an alloy should be used that contains nickel. Examples of these would be Easy Flo 3, Braze 505, Braze 630 and Braze 403. The nickel in these alloys helps prohibit interface corrosion within the steel. To learn more about interface corrosion please read Technical Bulletin No. T-9 or contact Lucas-Milhaupt Technical Service.
