Heat exchanger S31254
Thread Content
The heat exchange tubes of the heat exchanger are made of S31254. Are there any special requirements regarding quality management in its manufacturing process? Such as the mechanical properties and chemical composition listed in the material sheet, bending, welding, and other aspects
We mainly produce heat exchange tubes made of S31254; the corresponding patented grade for this material abroad is 254SMo. It contains a high level of molybdenum and is primarily used in environments with high chloride ion concentrations, such as seawater and brackish water. For the tube specifications, you can refer to standards such as ASME SA213. As for welding properties, it is possible to conduct assessments on these properties. The molybdenum content in this material is even higher than that in 904L; if your company has experience working with 904L, that can serve as a reference point
