Grade 12 Titanium Sheet
Grade 12 Titanium Sheet/Plate, also known as Ti-0.3Mo-0.8Ni (UNS R53400), is a low-alloy, corrosion-resistant titanium material. Compared to conventional Grade 2, it performs better in chloride-containing and reducing acid environments while maintaining good weldability and formability. It is often used as a cost-effective alternative to Grade 7 palladium-alloyed titanium in the chemical, offshore, and energy industries.
- Excellent corrosion resistance: Outstanding performance in reducing acids and chloride-containing environments.
- Cost-effective: Performance close to Grade 7 at a lower cost.
- Standards compliance: Complies with ASTM B265 / ASME SB-265 and provides traceable Material Traceability Certificate (MTC).

Advantages and Comparisons of Grade 12 Titanium Plate
Material selection not only affects the initial purchase cost but also determines the lifespan and maintenance costs of equipment in harsh environments. The following comparison table clearly illustrates the differences between Grade 12 titanium plate and more common materials.
Grade 2 vs. Grade 7 vs. Grade 12
| Comparison Items | Grade 2 | Grade 7 | Grade 12 |
|---|---|---|---|
| Corrosion Resistance | Good, but performance is insufficient in dilute hydrochloric acid, dilute sulfuric acid, and chloride ion environments. | Excellent, especially for environments with strong chloride ions and acids | Close to Grade 7, significantly better than Grade 2, with outstanding performance in pitting and crevice corrosion. |
| Cost | Low | High (due to palladium content) | Medium |
| Service Life | Medium | High | High |
| Weldability | Excellent | Excellent | Excellent |
| Typical Operating Conditions | Conventional chemical and seawater environments | Effective for applications requiring extreme corrosion and high lifespan | Suitable for highly corrosive environments such as chlorine-containing acidic media, FGD, and desalination. |
- Grade 2 is suitable for general chemical and seawater environments, benefiting from its low price. However, it performs poorly in reducing acids such as dilute hydrochloric acid and dilute sulfuric acid.
- Grade 7 is one of the most corrosion-resistant titanium materials, but it is more expensive. It is suitable for projects with ample budgets and extreme life requirements.
- Grade 12 performs similarly to Grade 7 in conditions like pitting and crevice corrosion, yet maintains a lower cost, making it the optimal balance for most corrosive environments.
Titanium vs. Stainless Steel vs. Nickel Alloy
| Comparison Items | Stainless steel | Nickel alloys | Grade 12 Titanium Plate |
|---|---|---|---|
| Corrosion Resistance | Susceptible to pitting and stress corrosion cracking in chloride ions and dilute acids | Good corrosion resistance, but limited in strong chloride environments | Excellent performance in dilute hydrochloric and sulfuric acids, as well as in chlorine-containing media |
| Cost | Low | High | Medium |
| Service Life | Medium-low, requires frequent maintenance | Medium-high, but heavier | High, minimal maintenance |
| Weight | Heavy | Heavier | Lightweight (density 4.51 g/cm³) |
| Life Cycle Cost (LCC) | Surface-cheap, but frequent maintenance and replacement lead to high overall costs | Very high initial cost, moderate maintenance | Moderate purchase cost, long service life, and lowest total cost of ownership |
- Stainless steel has a limited lifespan in chloride or acidic environments, requiring low short-term investment but requiring frequent long-term maintenance, resulting in higher overall costs.
- Nickel alloys offer excellent corrosion resistance, but are extremely expensive and heavy, hindering lightweighting and cost control.
- Grade 12 titanium plate combines lightweight, high corrosion resistance, and a long lifespan, offering moderate procurement costs and the lowest overall lifecycle cost.
Compared with Grade 2, Grade 7, stainless steel, and nickel alloys, Grade 12 titanium plate clearly demonstrates its unique advantages: near-high-end performance, significantly better cost, and a lifespan far exceeding that of traditional metals. It is the optimal material for achieving a balance between performance and cost in engineering projects.
