"The firemain system on Canadian warships was designed to be fabricated by silver brazing. Over the past number of years, some difficulties have been encountered when employing the brazing technique. To overcome these difficulties it is being proposed that the firemains on the new ships be of an all welded construction. An additional benefit will be a reduction in the overall weight of the firemain system. The erosion corrosion resistances of two potential replacement weldable alloys with sufficient strength were evaluated: cast chromium modified 70/30 copper nickel and cast niobium modified 70/30 copper nickel"--Abstract, page ii.
