Опубликовано Engineering Team, Shaanxi Qianyi Tuoda Technology Co., Ltd от 2026-10-25
1. Product Identity
We are titanium manufacturer based in Shaanxi Baoji China. Gr6 Ti‑5Al‑2.5Sn titanium bar is alpha‑type high‑temperature titanium alloy bar produced by hot forging and hot‑rolling process. It strictly complies with ASTM B348 standard. Outstanding thermal stability makes it suitable for aerospace high‑temperature structural parts, gas‑turbine auxiliary components and high‑temperature mechanical blanks. Stock sizes and custom‑length fabrication are available.

4. Mechanical & Corrosion Performance
-
Room‑temperature tensile strength: ≥735 MPa
-
Room‑temperature yield strength: ≥685 MPa
-
Elongation: ≥10%
-
High‑temp performance: Excellent thermal stability and creep‑resistance under long‑term high‑temperature working condition, less thermal‑strength attenuation.
-
Corrosion Resistance: Good corrosion resistance for atmospheric and seawater environment; mainly designed for high‑temperature service scenario, not for strong reducing acid medium.
-
Processing Feature: Alpha‑alloy, good thermal workability; argon shielding is required during welding operation.
5. Full Size Range
-
Diameter: 5‑70 mm rolled bar; larger diameter can be made by forging per drawing.
-
Length: Random rolled length or custom fixed cutting length.
-
Form: Round bar; square / flat bar can be customized upon technical requirement.
-
Custom options: Special tolerance, peeling processing, end‑face deburring.
6. Surface Treatment Options
-
Pickling surface: Remove hot‑rolling oxide scale, standard delivery condition for general machining blank.
-
Polished surface: Smooth finish for parts with strict surface requirement.
-
Peeling treatment: Remove surface decarburized and contaminated layer for high‑end aerospace blanks.

8. Strict Quality Control & Test Items
-
Raw ingot inspection: Chemical composition analysis for each vacuum remelting batch.
-
Hot‑rolling & heat‑treatment process parameter monitoring.
-
Dimension inspection: Diameter tolerance, straightness and length measurement for every bar lot.
-
NDT test: Ultrasonic UT inspection for internal inclusion, void and lamination defects.
-
Surface visual inspection: Check crack, scratch and iron contamination.
-
Issued documents: EN10204 3.1 MTC, mechanical test report, UT inspection record, batch traceability file.
9. Export Packaging & Shipment
-
Inner packing: Anti‑rust plastic film, foam spacer to avoid scratch and collision between bars.
-
Outer packing: Fumigated export wooden case for sea freight; fixed binding to prevent bar bending during transportation.
-
Marking: Laser mark grade, diameter, heat number on each bar end.
-
Trade terms: FOB, CIF, DDP; air freight for small‑batch aerospace blanks, sea freight for bulk orders.
