母液加热器904L超级奥氏体不锈钢的焊接

摘要

904L is a super austenitic stainless steel high chromium nickel molybdenum content, compared to 316L and 317L which has better corrosion resistance. This paper introduced material properties, forming, welding technology of the 904L super austenitic stainless steel, used it as material to make the mother liquor heater to enhance the mechanical properties of the product, confirmed the reasonable welding process and successfully applied it in practice.%904L是一种高铬镍钼含量的超级奥氏体不锈钢，相比316L和317L它具有更好的耐腐蚀性能，本详细介绍了904L超级奥氏体不锈钢的材料性能、工艺成形、焊接工艺等并通过将其用作母液加热器的制作材料提升了该产品的机械性能，确定了合理的焊接工艺并成功应用于实践。
