What are the types of stress corrosion cracking? How to do away with that?

  • The fasteners have made their special place in all the industries, that a lot of varieties of the same kind of the fastener is coming into existence. So here arises the point of the confusion. With such a large variety, the people get confused about which fastener they should choose. But it gets even more complicated when you have to choose the alloy which fits considerably best for the proper fastening needs.

    You should not choose the fasteners merely based on their strength. Rather you should find one which is extremely solid, harder, robust, and resistant. You should find resilient materials which are quintessentially essential. Their resistance depends on environmental stress.

    Also, it is required to choose the fasteners which can crack the corrosion. The corrosion can only be fought if the fastener is applied with the greatest resistance.

    Into how many parts, does the stress corrosion cracking is divided?

    • Liquid Metal Embrittlement
    • Chloride SCC
    • Caustic Embrittlement
    • Hydrogen Sulfide SCC

    Do you know

    If it is about the general corrosion resistance, then the fasteners made up of austenitic stainless steel are the best choice.

     Piece of advice

    If you are considering using the Chloride SCC, then before doing so, you have to carefully examine the situations in which they are supposed to be used.

    How can the susceptibility of general corrosion be reduced?

    There has to be some kind of protective coating on the fasteners which are made up of alloy steels. The protective coating can be either of the following types:

    • Cadmium Plating
    • Zinc Plating

    How can the cadmium and the zinc plating help to have the one-needed kind of fastener?

    These plate coatings are only used when the fasteners which are made up of carbon steel need galvanic protection. This practice would not be able to satisfy you if you are using the fasteners in considerably elevated environments.

    In which case is the LME possible?

    The LME is only possible if the zinc and the cadmium are getting used above the melting point temperature.


    Do not use the fasteners which have the protective coating of the zinc and the cadmium in high temperatures.
