Mechanized process contemporary society, stainless steel fastener, although is small components, but in the mechanical device is an essential part, also played the very vital role. Therefore we when use the fastener, needs to carry on the regular safeguarding maintenance, like this can guarantee a fastener more secure use, and can lengthen fastener's service life, enhances mechanical device's operational performance.
When we when carries on safeguarding to the fastener, which problems does the regular session have? It mainly has three major problems:
1st, in has carried on to the fastener quenching processes, must use the silicate cleansing agent to clean up the above impurity, then wants carefully to carry on the rinse, under avoids remaining the impurity above the fastener, affects to its normal application.
2nd, fastener after drawing temper, its color will change possibly, will soak the fastener after the ether period of time, will have the greasy material production, will have such situation to indicate that the fastener will be not very clean. After carrying on has analyzed, will detect to fastener heating time piles up is not very reasonable, the fastener will have some tiny oxidized phenomenon possibly in the middle of the quenching oil.
3rd, above fastener, if has white material time, very possible is some phosphides. Presents this kind of phenomenon the reason is because has not used the acidic clearer to carry on cleanly, moreover yo examination potcher time is not very careful.
If these questions cannot prompt processing, to the immediate influence to the fastener performance use, also will cause fastener's service life to lessen possibly, creates the fastener to get up early the damage phenomenon and so on. Above hoped that three major problem matters needing attention can help everybody better use fastener.
