ASTM B381 Titanium Forged Ring

Titanium forged rings supplied as forged, rolled, rough-machined or finish-machined blanks. Grade, dimensions, machining allowance, heat treatment, NDT and certification are reviewed against ASTM B381, ASME SB381 or the approved drawing.

Materials: Titanium Grades 2, 5, 7 and 12; other grades by review
Product Form: Forged ring, rolled ring, ring blank or machined ring
Standard: ASTM B381 / ASME SB381 or approved drawing
Documents: MTC, heat traceability and agreed inspection records

Product Detail

Product Introduction

Titanium forged rings are produced for components that require continuous circumferential grain flow, corrosion resistance and a controlled machining envelope. Each order should define alloy grade, outside and inside diameters, height, machining allowance, forging and heat-treatment route, surface condition, nondestructive testing and traceability.

Product Specifications

Product	ASTM B381 Titanium Forged Ring	Grade	Titanium Grades 2, 5, 7 and 12; order-specific alloy grade
Standard	ASTM B381 / ASME SB381 when expressly invoked for titanium forgings. Aerospace, pressure-equipment or drawing-controlled rings may require a specific AMS or customer specification, heat treatment, test coupon orientation and supplementary NDT.	Size & Form	Outside diameter, inside diameter, height, section size and machining allowance are confirmed by RFQ and approved drawing
Tolerance	As-forged, rough-machined or finish-machined tolerance according to the approved drawing	Supply Condition	Forged or rolled; annealed or order-specific heat treatment; as-forged, turned, bored or finish-machined surface
Inspection	MTC review, heat/lot traceability, chemistry and mechanical results, dimensional and surface inspection; ultrasonic testing, liquid-penetrant testing, macrostructure, microstructure or third-party inspection by agreement.	Documents	MTC, heat/lot traceability and agreed inspection reports
