8642 Round Bar: Material Profile
8642 is closely related to 8640 but should be purchased to the exact chemistry, hardenability, and mechanical requirements on the drawing.
The RFQ should identify the condition, diameter, property range, heat treatment, testing, and certification requirements.
Purchase to the controlling ASTM, SAE, AMS, or customer specification. Section size, supply condition, mechanical properties, surface limits, testing, and heat/lot traceability can change the acceptable material and processing route.
Key Characteristics
- Good hardenability
- High strength potential
- Good impact toughness
- Good fatigue performance
Common Applications
- Drive shafts
- Gears and spindles
- High-strength fasteners
- Heavy machinery parts
Specification Requirements
Identify the governing specification and revision, product form, section size, condition, mechanical properties, testing, and certification requirements. The purchase specification and material certification govern the order.
