Attachment 1 - TDP PNTDP0097 VER 002 SPMYM326Q4054.pdf

This is a Technical Data Package (TDP) for a Round Bar component (NIIN: PNTDP0097, Version 002) dated May 13, 2026, intended for use in critical shipboard systems where material failure could result in serious personnel injury, loss of life, or loss of the ship itself.

The item must be manufactured as an 18-inch diameter forged round bar in Class 5 steel, conforming to MIL-S-23284 specifications with Class A requirements. Manufacturing must include steel forgings for shafts and sleeves per MIL-S-23284 (15 June 1990), with mandatory first article inspection, melting practices per MIL-S-23284 paragraph 3.2, and vacuum degassing per MIL-S-23284 paragraph 3.2.1. The material is subject to extensive quality assurance requirements including Brinell hardness testing, heat treatment per MIL-STD-1684, stress relief temperature per MIL-S-23284, visual inspection, magnetic particle inspection, and ultrasonic inspection per T9074-AS-GIB-010/271 and MIL-S-23284. Repair welding is prohibited, and each forging must constitute a single lot. The contract mandates quantitative chemical and mechanical analysis certification, material traceability with permanent markings, nondestructive inspection per MIL-S-23284 specifications, and 100% material sampling inspection with zero-defect acceptance criteria. Additionally, the contractor must maintain ISO-9001-compliant quality systems, provide configuration control documentation, submit Engineering Change Proposals for any modifications, maintain Government Furnished Material (GFM) accountability with documented control procedures, and ensure all waivers and deviations receive Contracting Officer approval. Mercury-containing compounds are prohibited, and all documents must comply with applicable military specifications and standards referenced in Section 2.3, including ANSI/ASQ Z1.4, ISO 9002, ISO/IEC 17025, MIL-I-45208, MIL-STD-792, and various NAVSEA standards.
