Specifications: Standards and Classifications
Cobalt Alloy Pipe adheres to stringent industry standards to ensure quality and compatibility. Key specifications include:
Standards: ASTM B622, ASTM B619, ASME SB622, and DIN standards for seamless and welded pipes.
Grades: Common grades include Stellite 6, Stellite 21, cobalt-chromium alloys (CoCr), and nickel-cobalt alloys. Stellite, a well-known cobalt base alloy, is widely used for its wear resistance.
Composition: Typically contains 50-60% cobalt, 20-30% chromium, and varying amounts of nickel, molybdenum, and tungsten for enhanced properties.
Properties: High tensile strength (up to 1000 MPa), excellent corrosion resistance in acidic environments, and thermal stability up to 1200°C.
Cross-Validation: Specifications align with data from reliable sources like Matmatch and Special Metals, confirming adherence to ASTM standards and grade classifications.
Size Range: Dimensions and Customization
Cobalt Alloy Pipe and Cobalt Alloy Tube are available in a variety of dimensions to meet diverse project requirements:
Outer Diameter: 6 mm to 219 mm for seamless pipes; up to 610 mm for welded pipes.
Wall Thickness: 0.5 mm to 20 mm, depending on application.
Length: Standard lengths of 6 meters or 12 meters; custom lengths up to 15 meters available.
Custom Options: Tailored diameters, thicknesses, and lengths based on client specifications.
Cross-Validation: Size ranges are consistent with offerings from manufacturers like Huaxiao Metal and Yuhong Group, ensuring industry-standard dimensions.
Types: Forms, Processes, and Finishes
Cobalt Alloy Pipe comes in various forms, processes, and surface treatments to suit specific needs:
Shapes: Seamless, welded, round, and rectangular pipes.
Processes: Hot-rolled, cold-drawn, or extruded for seamless pipes; ERW or SAW for welded pipes.
Surface Treatments: Polished, annealed, or coated with anti-corrosive layers for enhanced durability.
Special Variants: Cobalt-chromium alloy pipes for biomedical applications and Stellite-coated pipes for extreme wear resistance.
Applications: Common Grades and Uses
| Grade | Industry | Specific Uses |
|---|---|---|
| Stellite 6 | Oil & Gas, Power Generation | Valve components, turbine blades, erosion shields in high-temperature environments |
