青海快3The sleeve joint has great strength, but if it is used in the high-temperature environment, the sleeve joint will appear embrittlement. In order to avoid this phenomenon, we need to avoid using the sleeve joint in the high-temperature environment as much as possible.
A bayonet joint is a contact where two or more parts are to be welded together。 Or of two or more parts connected by a bayonet, including welds, fusion zones and heat affected zones。 The area where the sleeve is melted and solidified is called the weld, which consists of the molten base material and the filler metal。
The embrittlement of the sleeve joint is not low in strength, but sometimes it will occur in the weld or near seam area within a few months after use, which is more likely to occur in extreme temperature environment. Because the weld of stainless steel in high temperature heating for a period of time, the impact toughness decline phenomenon called embrittlement.
