In this blog by fasteners manufacturer in United States , choosing fasteners with the right strength you need is the calm part. Harder, however, is searching the corrosion resistance you are looking for. Strong materials are essential. How resistant they need to be can depend on the environmental pressure that will be applied to them. To resist corrosion cracking, the highest level of resistance must be provided, even if slight corrosion cracking ends up occurring. So, the question remains, how to choose the right fastener? Stress Corrosion Cracking Notable types of stress corrosion cracking: · Liquid metal embrittlement · Caustic embrittlement · Hydrogen sulfide HSSC · Chloride SCC Adequate common corrosion resistance is offered by austenitic stainless-steel fasteners.
