Description
ASTM F1537 CoCrMo Bar – Alloy Type and Material Condition
🔹 Product Overview
ASTM F1537 CoCrMo Bar is a wrought cobalt-chromium-molybdenum material for bar enquiries. ASTM F1537 covers three wrought alloys in bar, rod and wire forms. Specify the alloy type, material condition and ordered acceptance criteria; ISO 5832-12 is a separate raw-material reference for two wrought alloys and requires confirmation for the selected grade. The device manufacturer establishes suitability for the finished medical device.
🔹 Key Features & Advantages
- ✅ Strength Requirements – The catalogue reference lists tensile strength > 1000 MPa; confirm the required material condition and batch test results for the order.
- ✅ Corrosion Resistance – Define the service environment and corrosion assessment for the ordered alloy, surface and processing condition.
- ✅ Biocompatibility Evaluation – Assess the finished device, surface condition and processing residues for the intended biological contact.
- ✅ Wear Resistance – Specify contact loading, finish and wear or fatigue test requirements for the intended component.
- ✅ Service Conditions – State the operating temperature, loading and applicable engineering specification for industrial or aerospace enquiries.
🔹 Standards & Grades
The ASTM F1537 CoCrMo Bar reference distinguishes three wrought alloy types. State the requested type and UNS designation in the enquiry and confirm the quoted grade and supplied condition:
| Alloy Type | UNS Number | Carbon Content | Typical Use |
|---|---|---|---|
| Alloy 1 | R31537 | Low carbon | Preferred for implants requiring high toughness |
| Alloy 2 | R31538 | High carbon | Offers higher strength and hardness |
| Alloy 3 | R31539 | Dispersion strengthened | High fatigue resistance applications |
For an ISO 5832-12 material requirement, confirm the selected alloy, edition, condition and inspection results separately. Its two-alloy scope is not an automatic equivalence claim for every ASTM F1537 type.
🔹 Chemical Composition (Catalogue Reference)
| Element | Content (%) |
|---|---|
| Cobalt (Co) | Balance |
| Chromium (Cr) | 26.0 – 30.0 |
| Molybdenum (Mo) | 5.0 – 7.0 |
| Nickel (Ni) | ≤ 1.0 |
| Iron (Fe) | ≤ 0.75 |
| Manganese (Mn) | ≤ 1.0 |
| Silicon (Si) | ≤ 1.0 |
| Carbon (C) | ≤ 0.35 |
| Nitrogen (N) | ≤ 0.25 |
The composition table is a catalogue reference, not the certified acceptance range for every alloy type. Confirm the selected grade, carbon class, standard edition and batch chemical analysis against the purchase requirements.
🔹 Mechanical Properties
| Property | Value |
|---|---|
| Ultimate Tensile Strength | ≥ 1000 MPa |
| 0.2% Yield Strength | ≥ 750 MPa |
| Elongation | ≥ 8% |
| Hardness | 250 – 350 HBW |
| Modulus of Elasticity | ~ 210 GPa |
The mechanical table is a catalogue reference for ASTM F1537 CoCrMo Bar. Confirm the ordered alloy type, material condition, test method and batch acceptance results for the intended loading and manufacturing application.
🔹 Supply Conditions & Dimensions
- Diameter Range: 6 mm – 80 mm (customizable)
- Length: 1000 mm – 3000 mm (cut-to-length available)
- Condition: Specify the required forged or solution-annealed condition and ground or polished finish; confirm the quoted route and condition
- Inspection Documents: Specify EN 10204 3.1 MTC and batch-identification requirements; confirm the documents supplied with the quotation
For CoCrMo Rod or wire enquiries, specify the form, alloy type and supplied condition, and confirm the applicable ASTM F1537 requirements and quotation.
🔹 Application Enquiries
- 🏥 Medical: Hip and knee joint replacements, bone plates, dental implants, screws, and spinal fixation devices.
- ⚙️ Industrial: Pump shafts, valve seats, and wear-resistant components in corrosive environments.
- ✈️ Aerospace: High-load, high-temperature parts requiring superior wear resistance.
For ASTM F1537 CoCrMo Bar, define the applicable raw-material requirements for the listed component examples. Finished-device manufacturing, surface processing and application-specific validation determine suitability.
For the wrought raw-material scope, see ISO 5832-12:2019 wrought CoCrMo alloys. Confirm its applicability to the selected alloy and order requirements; finished-device assessment is a separate manufacturing responsibility.
🔹 Quality & Compliance
For an ASTM F1537 CoCrMo Bar order, specify any ultrasonic examination, grain-size inspection and mechanical verification requirements. Confirm the required batch documents with the quotation, such as:
- ✅ EN 10204 3.1 Certificate
- ✅ Chemical Composition Report
- ✅ Mechanical Test Report
An ISO 5832-12 requirement needs verification for the selected wrought alloy and supplied condition. Material documents and finished-device validation serve different acceptance purposes.
🔹 Advantages of Choosing Our CoCrMo Bar
- 🌟 Dimensional Requirements – Specify ground-bar tolerances and finish, and confirm the quoted capability
- 🌟 Material Condition – Define the required melting or forging route and any microstructure inspection; confirm the actual batch documentation
- 🌟 Alloy Selection – Identify Alloy 1, Alloy 2, or Alloy 3 and confirm the quoted grade and condition
- 🌟 Delivery Planning – Confirm quantity, inspection documents and delivery timing with the quotation
🔹 FAQ
Q: What is the difference between Alloy 1 and Alloy 2?
A: Alloy 1 is the lower-carbon type and Alloy 2 the higher-carbon type. Select the required alloy and material condition, then verify the batch chemistry and mechanical results; toughness, hardness and wear behaviour also depend on processing and testing.
Q: Can you supply ISO 5832-12 equivalent bars?
A: State the required ISO edition, alloy and material condition with an ASTM F1537 CoCrMo Bar enquiry. Confirm the selected raw-material criteria and supporting batch documents; the ASTM and ISO scopes do not automatically make every alloy type interchangeable.
Q: Do you provide small batch orders for prototyping?
A: Yes, we support small MOQ orders and sample pieces for R&D and prototyping.
