MIL-HDBK-843

Abstract

This handbook provides Naval Sea Systems Command (NAVSEA) guidance for the selection or substitution of the most common material types and forms used in ship design, construction, overhaul, or repair. Recommended specifications have been established and cross-indexed to prior specifications. By using the consolidated material specifications provided by this handbook, the volume of redundant specifications, stock numbers, and associated material inventories can be reduced. <br>A reduction in the volume of redundant specifications, stock numbers and associated material inventories can be accomplished through the use of the consolidated material specifications provided by this handbook. Recommended specifications have been established and cross indexed to the prior specifications. <br>This handbook applies to material applications for combatant and noncombatant ships controlled by the following documents (see appendix): NAVSEA 0900-LP-006-9010, NAVSEA 0900-LP-000-1000, NAVSEA 0900-LP-060-4010, NAVSEA 0900-LP-014-5010, NAVSEA 0900-LP-001-7000, NAVSHIPS 0900-LP-014-1010, NAVSEA 0991-LP-023-3000, NAVSEA 0900-LP-082-3010, NAVSEA S9A00-AB-GOS-010/GSO, NAVSEA 0902-018-2010, NAVSEA S9AA0-AA-SPN-010/GEN SPEC, MIL-STD-278, MIL-STD-438, MIL-STD-777, MIL-STD-1681, MIL-STD-1688, and MIL-STD-1689. This handbook does not apply to any of the following: (a) systems and components under NAVSEA Code 08 cognizance in nuclear powered ships and tender nuclear support facilities, (b) systems identified in NAVSEAINST C9210.4, (c) SUBSAFE or non-nuclear material control Level I applications. Recommended material specifications may be invoked for initial design, alteration, or repair applications of material types and forms covered by this handbook. Whenever repair or overhaul work results in the removal and discard of material, replacement may be made using the recommended material specification. When acquiring material for the Naval Supply System stock, the recommended material specifications may be invoked in the acquisition document in lieu of the previous material specifications. <b><u>Intended Use:</u></b> This handbook is intended to permit one-way substitution from previous specification to the recommended specification. This handbook is also intended to give designers a source of material specifications. <br>
