1.4840 Fasteners Specification
AISI 310 it has very good and appreciable properties with good ductility and weldeabilty. It has good oxidation resisatnce at higher temperatures as 1150 Degrees celcious. As it has more chromium and nickel content, as it is superior in most environmnets. It is used in over linings, boiler baffles, lead pots, combustion tubes, refractory. This type of rade is easily welded using fusion or resiatnce method, however, oxytelene welding is not recommended. During hot working rapid cooling is required to maximize corossion resistance.
