Technical Data Package Summary

This is a Technical Data Package (TDP) for Round Bar (LSN: 9510-LL-D00-0318 L1, Version 001) under contract SPMYM326Q3126, effective January 24, 2026. The material is designated as a Special Emphasis critical shipboard component for use in crucial naval shipboard systems, with defective material posing serious risk of personnel injury, loss of life, or vessel failure. The item is manufactured per SAE-AMS-QQ-S-763 specifications with specific requirements for steel bars, wire, shapes, and forgings in corrosion-resistant steel, including form (10-inch round), finish, melting practice (electric furnace, induction, vacuum furnace, or electroslag remelt), and various processing constraints (no special cleaning, no machining allowances for major surfaces, low magnetic permeability requirements for 300-series austenitic corrosion-resistant steels).

The TDP establishes comprehensive requirements for testing certification, material handling, traceability, and quality assurance. Key testing includes hardness (SAE-AMS-QQ-S-763), intergranular corrosion (prior to fabrication), ultrasonic inspection (T9074-AS-GIB-010/271), and macrostructure analysis. Material must undergo 100% inspection for traceability marking and legibility with permanent markings applied per MIL-STD-792 on each pipe, tube, and metal bar end. Certification data must include quantitative chemical and mechanical analysis, heat/lot numbers, and heat treat numbers where applicable. Configuration control requires Government maintenance of baseline configuration with Engineering Change Proposals submitted through ECDS (Electronic Contractor Data Submission). Quality system compliance must follow ISO-10012 or ANSI/ASQ Z1.4 standards with ISO-17025 accreditation. The contract references multiple military specifications (MIL-I-45208, MIL-STD-45662, MIL-STD-792) and SAE standards (SAE AMS 2806, 2807, 2809, AMS-QQ-S-763, AMS-STD-185), along with ANSI/NCSL, ASTM, and ISO/IEC standards for compliance verification.
