Steel which has a sulfur content ranging from 0.12-0.33% and which then exhibits free cutting properties. Made for screw machine products
The welding position in which the weld face lies in an approximately vertical plane and the weld axis at the point of welding is approximately horizontal.
Also known as ?auto crack,? resulting from stress concentration in relatively thin weld metal that is last to freeze. Both root cracks and crater cracks are forms of hot cracking.
