Structured specification reference
| Parameter | Reference / acceptance condition |
|---|---|
| Grade | 34CrNiMo6 |
| Specification reference | EN 10083-1; exact edition to be agreed |
| Application boundary | Engineering component steel: specify core properties, heat treatment and any surface-hardening requirements separately. |
| Mechanical acceptance | Confirm thickness-dependent values in the specified product standard and heat certificate |
| Chemical acceptance | Confirm heat analysis against the exact contract edition; no automatic equivalence |
| Delivery condition | As ordered and shown on certificate; verify any legacy designation |
| Dimensions and tolerance | Product-form-specific standard and ordered class |
| Class approval | Only where expressly required and accepted for this product |
34CrNiMo6 designation and selection
34CrNiMo6 is a nickel-chromium-molybdenum engineering-steel designation. Consider the complete section and treatment when specifying demanding components. It must not be confused with 42CrMo4 merely because a legacy description copied the wrong grade name; chemical identity and certificate traceability take precedence over that description.
Enquiry fields for EN 10083-1 34CrNiMo6
Confirm the exact edition, product form and dimensions, final delivery condition, quantity, equipment duty and accepting authority. Ask the producer for thickness-specific mechanical requirements and the complete heat analysis. If the application is classed, specify the required approval and inspection documents before production.
Certificate review and release
Connect the specified material to the delivered heat and piece IDs, then review the results and final condition. Sampling, test temperature, specimen geometry and any supplementary examination must match the order. Resolve missing evidence before releasing the material for fabrication. A cross-reference handbook is a comparison aid; the applicable standard and accepting engineer determine the final decision.
Order parameters
- Thickness / size scope
- Product-form and contract specific
- Delivery condition
- Verify the complete grade and final condition
- Class society requested
Society names are enquiry options. Approval and certificate scope must be confirmed for the actual material.
Frequently asked questions
Is this automatically equivalent to a shipbuilding hull grade?
No. The approved application specification and accepting authority must establish suitability.
