1.1 This specification covers alloy steel forgings for carburizing applications.
1.2 Forgings are considered weldable under proper conditions. Welding technique is of fundamental importance and it is presupposed that welding procedure and inspection shall be in accordance with approved methods for the class of material used.
1.3 This specification is expressed in both inch-pound units and in SI units. However, unless the order specifies the applicable M specification designation (SI units), the material shall be furnished to inch-pound units.
1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
