Gr12 Ti-0.3Mo-0.8Ni Titanium Bars

Gr12 Ti-0.3Mo-0.8Ni titanium bars is a titanium-molybdenum-nickel alloy (Ti-0.3Mo-0.8Ni), corresponding to the American grade Gr.12, and conforms to standards such as ASTM B348. It has a titanium content of up to 99.7%, a density of approximately 4.5 g/cm³, a wide operating temperature range (-253℃ to 600℃), a tensile strength ≥485 MPa, and an elongation exceeding 18%. By adding molybdenum and nickel, its corrosion resistance in chloride and acidic environments is significantly superior to pure titanium, making it particularly suitable for high-temperature, high-pressure, or highly corrosive environments.

The chemical composition of Gr12 Ti-0.3Mo-0.8Ni titanium alloy is as follows:

Titanium (Ti): Balance (content ≥99.7%)

Molybdenum (Mo): 0.2%–0.4%

Nickel (Ni): 0.6%–0.9%

Iron (Fe): ≤0.30%

Carbon (C): ≤0.10%

Nitrogen (N): ≤0.03%

Hydrogen (H): ≤0.015%

Oxygen (O): ≤0.25%

• High corrosion resistance: Exhibits excellent performance in chloride and acidic environments, with outstanding resistance to crevice corrosion.
• Good mechanical properties: High tensile strength, good elongation, and impact toughness.
• Wide process adaptability: Easy to weld, forge, roll, and process; surface finish can be smooth or rough.

• Aerospace: Engine components, structural parts.
• Chemical Equipment: Reactors, heat exchangers, pipelines.
• Nuclear Power Plants: Corrosion-resistant structural parts.
• Marine Engineering: Seawater desalination equipment, offshore platforms.
• Medical Field: Implants, surgical instruments.

The mechanical properties of Gr12 Ti-0.3Mo-0.8Ni titanium bars are as follows:

Tensile strength: ≥485MPa, reaching 548MPa at a solution temperature of 920℃.

Yield strength: 420MPa at a solution temperature of 920℃.

Elongation: >18%, reaching 23% at a solution temperature of 860℃.

Density: Approximately 4.5g/cm³, some data suggest 4.51g/cm³.

Hardness: Vickers hardness (HV) reaches 240HV after solution treatment; Brinell hardness (HB) is 180–215HB.

Elastic modulus: 10³–10⁷ GPa.

Phase transition point: 890℃±15℃.

These properties make it suitable for applications in aerospace, chemical, and nuclear power industries.
