Characteristics |
- A general purpose alloy machinery steel with improved machinability as a result of an aim sulfur content. The product may or may not include the injection of a minute quantity of calcium. The calcium treatment modifies the sulfide inclusions in the steel to a much more globular form. Calcium also combines with the aluminates to form softer inclusions. The net effect (sulfur and calcium) is improved machinability and longer tool life.
- Bars are supplied in the heat treated and stress relieved condition to a hardness level of approximately HB300 and are suitable for many service applications where strength and toughness are required
