Material Fatigue and Stress<\/strong><\/p>\n What is Material Fatigue? We can prevent it using below measures:<\/p>\n Improper Installation Techniques<\/strong><\/p>\n There are several common improper installation techniques<\/p>\n Corrosion and Environmental Damage<\/strong><\/p>\n Corrosion or environmental damage occurs when material get affected due to chemical or electrochemical reactions. Moisture, salt, chemicals, and temperature cycling plays important role in environmental damage of fasteners.<\/p>\n Below are several types of corrosion which effects fasteners:<\/strong><\/p>\n Galvanic Corrosion:<\/strong> Mixed metal fasteners which are not compatible with each other when comes in contact within a corrosive environment, It accelerates a corrosion of fastener. Material and Size Selection Errors<\/strong><\/p>\n Selecting wrong size fasteners for application creates a condition of early failure. Using low strength or wrong material can face a issues like galvanic corrosion, fatigue cracking or excessive wear or deformation.<\/p>\n Size selection is also important to prevent fasteners failures, Undersized or Oversized fasteners may not fit properly and can lead to uneven load distribution or bending.<\/p>\n Inaccurate Load Calculations<\/strong><\/p>\n If actual load exceeds the design capacity fasteners can fail. Overloading occurs when calculated working load lacks the sufficient margin.<\/p>\n","protected":false},"excerpt":{"rendered":" Material fatigue in fasteners occurs when its under cyclic loading Material Fatigue and Stress What is Material Fatigue?

\nGeneral Corrosion:<\/strong> It happens due to exposure of moisture and oxygen.
\nStress Corrosion Cracking:<\/strong> It happens due to mechanical stress and corrosive attack on fasteners. Stainless steel fasteners<\/a> are more susceptible to it in chloride environments.<\/p>\n
