1.1 Form:
This specification covers an airci’att-quality, low-alloy steel in the form of mechanical tubing.
1.2 Application:
This product has been used typically for parts, 0.875 inch (22.22 mm) and under in section thickness at time of heat treatment, requiring a through-hardening steel capable of developing hardness as high as 50 NRC, and also parts of greater thickness but requiring proportionately lower hardness, but usage is not limited to such applications.
2. APPLICABLE DOCUMENTS:
The issue of the tollowing documents in effect on the date of the purchase order forms a part of this specification to the extent specified herein. The supplier may work to a subsequent revision of a document unless a specific document issue is specified. When the referenced document has been canceled and no superseding document has been specified, the last published Issue of that document shall apply.
