Grade 7 Titanium Welded Tube Thin Wall Titanium Tubing High Strength Corrosion Resistance

Titanium Grade 7

Introduction

Titanium alloys have several advantageous attributes that allow their use in industries like automobiles,

consumer electronics, military, aerospace, medical, marine, and sports equipment.

Grade 7 Ti-0.15Pd alloy is highly resistant to corrosion in reducing acids and localized attack in hot

halide media. The presence of palladium helps to enhance the alloy’s corrosion resistance. This alloy

is similar to grade 2, and possesses medium strength and ductility.

The following sections will discuss in detail about grade 7 Ti-0.15Pd alloy.

Chemical Composition

The chemical composition of grade 7 Ti-0.15Pd alloy is outlined in the following table.

Physical Properties

The physical properties of grade 7 Ti-0.15Pd alloy are tabulated below.

Mechanical Properties

The following table shows the mechanical properties of grade 17 Ti-0.05Pd alloy.

Thermal Properties

The thermal properties of grade 7 Ti-0.15Pd alloy are tabulated below.

Welding

Weldability of grade 7 Ti-0.15Pd alloy is rated as excellent. This alloy is a single-phase material,

hence the microstructure of the alpha phase is not affected by thermal treatments or welding

temperatures.

Annealing

Annealing of this material can be performed by heating to 650-760°C (1202-1400°F) for 6 min -2 h

and then air-cooled. In case stress relieving is required, the material has to be heated to 480-595°C

(896-1103°F) for 15 min - 4 h, and then air-cooled.

Applications

Grade 7 Ti-0.15Pd alloy is used in the following application areas:

• Anode/cathode/cell components

• Chemical processing equipment

• Air pollution control equipment

• Pulp/paper bleaching/washing equipment

• Hydrometallurgical extraction/electrowinning

• Desalination, brine concentration/evaporation
