The ASTM B338 Grade 2 titanium alloy is the material of choice for cold rolled round alloy seamless titanium tubes designed for heat exchanger applications. This alloy is known for its excellent corrosion resistance, high strength-to-weight ratio, and exceptional biocompatibility, making it suitable for various demanding environments.
The ASTM B338 specification outlines the requirements for seamless and welded titanium and titanium alloy tubes used in heat exchangers and other industrial applications. The Grade 2 designation signifies the specific alloy composition and mechanical properties that the tubes must adhere to.
The chemical composition of ASTM B338 Grade 2 titanium alloy is as follows:
Element | Percentage (%) |
---|---|
Titanium | 99.2 min |
Iron | 0.30 max |
Oxygen | 0.25 max |
Carbon | 0.10 max |
Nitrogen | 0.03 max |
Hydrogen | 0.015 max |
The mechanical properties of ASTM B338 Grade 2 titanium alloy ensure its suitability for heat exchanger applications, where durability and thermal efficiency are crucial.
Property | Value |
---|---|
Tensile Strength | 50 ksi (345 MPa) min |
Yield Strength | 40 ksi (275 MPa) min |
Elongation | 20% min |
Hardness (Rockwell) | C35 max |
Density | 0.163 lb/in³ (4.51 g/cm³) |
While the term "steel grade" is commonly used, it's important to note that ASTM B338 Grade 2 is not a steel alloy but rather a titanium alloy. This distinction is crucial, as titanium offers unique properties that differentiate it from traditional steel materials.
The ASTM B338 Grade 2 titanium tubes find extensive application in the field of heat exchangers. Their exceptional resistance to corrosion, even in harsh environments, makes them ideal for transferring heat between different fluid streams without compromising the integrity of the tubes. These tubes are used in industries such as chemical processing, petrochemicals, power generation, desalination, and aerospace, where reliable heat exchange is paramount.
