to find the type of crack based on surface appearance.
(OP)
hello everyone,
i need to find that what type of crack is it? Is it possible to differentiate between cracks visually whether it is quench crack or RM crack or Grinding crack? and what is the corrective action to avoid such type of cracks.the material is En353 and case carburised and then finish grinding is done.
2. i have a similar type of issue in forging of Forks of tractors, i am constantly facing crack issue in forging. please suggest me some corrective actions to avoid crack in SAE1045 forging.

But in most cases you need to remove a portion and section it to really know.

Similar effects as per the pictures come from nonmetallic inclusions which are formed out into linelike surface flaws during rolling / forging and result in surface cracks during heat treatment.
