产品特性DESCRIPTION

SWE309LMo较SWE309L添加了2.0%-3.0%的Mo，以增加其在含氟F、氯Cl、溴Br、碘I环境中的点蚀抗性。SWE309LMo药芯焊丝主要应用是母材的表面改性，以提高其耐蚀性。它还用于多层堆焊的打底层，填料金属如SWE316或SWE317不锈钢。如果没有SWE309Mo的打底层，防止铬和钼等元素的过量稀释。

Compared with SWE309L, SWE309LMo has an additional 2.0%-3.0% molybdenum (Mo) added to enhance its pitting corrosion resistance in environments containing fluorine (F), chlorine (Cl), bromine (Br), and iodine (I). The main application of SWE309LMo flux-cored wire is surface modification of base metals to improve their corrosion resistance. It is also used as the backing layer in multi-layer surfacing, with filler metals such as SWE316 or SWE317 stainless steel. Without the backing layer of SWE309Mo, it can prevent excessive dilution of elements such as chromium (Cr) and molybdenum (Mo).

应用APPLICATIONS

用于焊接耐硫酸介质（硫氨）腐蚀的同类型不锈钢容器，也可作不锈钢衬里、复合钢板、异种钢的焊接。

It is used for welding stainless steel vessels of the same type that resist corrosion from sulfuric acid media (ammonium sulfate). It can also be used for welding stainless steel linings, clad steel plates, and dissimilar steels.
