一种外层为不锈钢、内层为低合金铁素体的复合钢管已被瑞典的Sandvik钢公司开发出。这种复合管用于废物焚化锅炉中的水墙、蒸发器和高温加热器中达到了最佳的耐腐蚀性能。这种复合管所采用的外层管是Sandvik公司制造的不锈钢类Sanicro63和Sanicro65。内层管为采用ST458（ASTMAZ
A composite steel tube with an outer layer of stainless steel and an inner low-alloy ferrite has been developed by Sandvik Steel in Sweden. This composite pipe is used for optimum corrosion resistance in water walls, evaporators and high temperature heaters in waste incineration boilers. The outer pipe used for this composite pipe is Sanicro 63 and Sanicro 65, stainless steel manufactured by Sandvik. The inner tube for the use of ST458 (ASTMAZ
