Falhas em componentes de sustentação – Cabos de Aço, Correntes e Ganchos
11
A typical ductile fracture in Grade 30 chain. Note that yielding and plastic deformation have occurred in all links. This demonstrates the gradual and progressive failure of the chain and is desirable.
12
A more brittle fracture in stainless steel chain, at or near to a weld. There is noticeably less deformation of the links prior to failure. Although the load sustained was well above the nominal strength of the chain, failure in a brittle mode is less desirable as it could occur with a snatch load.

Swing S hooks which were thinned to the point of eventual failure
