Stainless steel corrosion failures often result from grain boundary sensitization. Many 300 series stainless steel alloys come in two grades or more. For example 304 stainless steel comes as 304, 304L and 304H. Each grade has a different amount of carbon (C). the 304 grade allows up to .0.08% C; whereas 304 L allows a […]
Failure Analysis Expert Examines a Corrosion Failure
Corrosion engineer performed a metallurgy failure analysis to determine the cause of prematurely failing burners in a particular brand of gas grill. The burners in question would fail completely after two or three years of service. The failure analysis of the burner revealed that the grill manufacturer made the subject gas burners from an inferior […]
Failure Analysis of Corroding Stainless Steel Probe
Failure analysis expert was asked to determine the cause of deterioration of the tip of a stainless steel (SS) probe used to measure the level of hot tomato juice in a vat. Chemical analysis identified the steel as 304 SS with 0.082% carbon. At best, the carbon limit is on the high end in […]
