Titanium tanks and Bent Parts are industrial vessels made primarily of titanium and titanium alloys; the choice of material and their performance characteristics are directly linked to the requirements of the specific application.
I. Classification of Mainstream Materials
1. Industrial-Grade Titanium (Gr1/Gr2)
Titanium content ≥99.5%, oxygen content ≤0.25%; offers basic corrosion resistance and good weldability;
Typical applications: Chemical acid and alkali tanks, electroplating tanks (e.g., copper/nickel electroplating anode baskets).
2. Corrosion-Resistant Titanium Alloys, such as Gr12 (Ti0.3Mo0.8Ni) and Gr7 (Ti-0.2Pd)
The addition of palladium and/or molybdenum enhances resistance to crevice corrosion, with an annual corrosion rate of only 0.255 mm in 20% hydrochloric acid;
Typical Applications: Petroleum refining reaction towers, equipment for high-temperature, high-chloride environments.
3. Medical-grade titanium alloys (e.g., Ti-6Al-4V ELI)
Aluminum and vanadium content is reduced to meet biocompatibility requirements; used in pharmaceutical aseptic storage tanks.
II. Key Performance Indicators
Corrosion resistance: Forms a self-healing oxide film in media such as 98% sulfuric acid and seawater;
Mechanical Properties: Tensile strength 28–160 kgf/mm², density 4.51 g/cm³, specific strength exceeds that of steel;
Thermal Stability: No significant performance degradation between -253°C and 500°C; the oxide film remains stable at high temperatures;
Processing Characteristics: Requires shielded welding (e.g., TIG welding); cold forming is relatively difficult; welding porosity must be controlled below 0.5%.
III. Material Selection Guidelines
Chemical Industry: Prioritize Gr12 (Ti0.3Mo0.8Ni) alloy, which offers 10 times the resistance to crevice corrosion compared to pure titanium;
Food and Pharmaceutical Industries: Must comply with FDA standards; Gr1 ELI-grade ultra-low-impurity pure titanium is recommended;
Cost-Sensitive Applications: Titanium-steel composite plates can reduce costs by 40% while maintaining corrosion resistance at the interface.
In summary: Both titanium tanks and titanium bent parts exhibit excellent overall corrosion resistance, thanks to the formation of a dense, stable oxide layer on the titanium surface, which performs exceptionally well in most oxidizing and neutral environments.
Key Advantages: As storage and transport containers, titanium tanks exhibit virtually no corrosion in seawater, chloride solutions (salt spray), wet chlorine gas, and most oxidizing acids, ensuring long-term, stable performance. In seawater environments, they maintain excellent corrosion resistance even at operating temperatures as high as 121°C.
