H-Shaped Titanium and Titanium Alloy Profiles - China Suppliers and Factory, Gr2/Gr5/Gr7, ASTM B348 Standards
Products Detail
Titanium H-section profiles are H-shaped beams (with an “H” cross-section) made from titanium or titanium alloys. They feature high strength, lightweight properties, and excellent corrosion resistance. The “double web + flange” structural design combines high bending strength with lightweight advantages. Paired with titanium's inherent corrosion resistance, it serves as a core structural component for “load-bearing + weather-resistant” applications in marine and high-end infrastructure sectors. Grades are tailored to meet diverse requirements:
I. Core Characteristics: Dual Advantages of Structure and Material
High strength, low weight. The H-shaped cross-section distributes stress, offering 30% higher bending strength than steel profiles of equivalent weight. Titanium's density of 4.51 g/cm³ is 43% lighter than steel, significantly reducing overall equipment load.
Maintains stability across diverse media. GR2 resists fresh water/mild corrosion, GR5 withstands extreme temperatures/fatigue, GR7 endures acid/salt spray—adapting to harsh environments.
Supports custom flange widths (30-150mm), web heights (50-200mm), and wall thicknesses (3-12mm). Enables direct welding and assembly, minimizing secondary processing.
II. Grade-Specific Applications
III. Key Advantages: Core Reasons for Replacing Traditional Materials
Compared to steel H-beams (prone to rust, heavy weight) and aluminum alloy H-beams (low strength, poor acid resistance), titanium and titanium alloy H-beams achieve “load-bearing without added weight, corrosion resistance without replacement.” They are particularly suited for long-term structural support in outdoor, underwater, and highly corrosive environments.
Frequently Asked Questions
Titanium H-section profiles offer 30% higher bending strength than steel profiles of equivalent weight. Additionally, titanium's density (4.51 g/cm³) is 43% lighter than steel, which significantly reduces the overall structural load of the equipment.
GR5 titanium alloy H-beams are ideal for high load capacity and harsh environments. They can withstand extreme temperature variations ranging from -50°C to 400°C and offer a long fatigue life of up to 20 years.
GR2 pure titanium H-beams are designed for light load-bearing and basic corrosion resistance. Typical applications include load-bearing walkways on offshore platforms and equipment support structures in food processing facilities.
GR7 titanium alloy H-beams provide superior resistance to highly corrosive media like dilute sulfuric acid and organic acids. They are widely used as support beams for acid tanks and hydrometallurgical frameworks, offering a service life exceeding 10 years.
They support custom dimensions including flange widths of 30-150mm, web heights of 50-200mm, and wall thicknesses ranging from 3-12mm to meet specific structural and engineering requirements.
