Plan the heat-treatment stage
Separate incoming hardness from the final material condition. If a thermal cycle follows machining, identify which features require final finishing afterwards.
Metal / CNC MATERIALS
Inconel & Nickel Alloy CNC Machining
Review a nickel-alloy part by its exact grade and condition, including Inconel 625 or 718 requirements.
CNC milling & turning · Drawing-based orders
625 and 718: why does the supplied condition matter?
Special Metals describes 625 as a solid-solution-strengthened alloy; 718 has an age-hardening route. The incoming condition and any final heat treatment therefore belong in the machining scope. OUJI has machined nickel alloys, but that family-level experience does not establish every listed grade or condition as a completed project.
01 / MATERIAL SPECIFICATION
Nickel alloys grades & conditions.
Match the full designation on your drawing. Frequent machining experience, published project evidence and specifications for review are shown separately.
| Grade / designation | Experience | Include with your drawing | Inquiry |
|---|---|---|---|
| Inconel 625 | Specify for review | Inconel 625: include UNS N06625 and the specified product condition when required by the drawing. | Quote grade ↗ |
| Inconel 718 | Specify for review | Inconel 718: state whether stock is solution treated or aged and whether final aging is included. | Quote grade ↗ |
| Inconel 600 | Specify for review | Inconel 600: preserve its own alloy and product specification instead of ordering a generic Inconel stock. | Quote grade ↗ |
| Monel 400 | Specify for review | Monel 400: identify the nickel-copper alloy and supplied condition; it is not a 625 or 718 substitute. | Quote grade ↗ |
| Invar 36 | Specify for review | Invar 36: include the temperature range and verification if low thermal expansion is an acceptance criterion. | Quote grade ↗ |
OUJI machining experience: confirmed by the company owner, 10 September 2026. Family-level experience does not establish a specific grade, stock condition or customer end use; see individual row and case evidence.
Listed grades do not imply current inventory. Material condition, stock form and documentation are agreed with the quotation.
02 / MACHINING REQUIREMENTS
Make the drawing ready for review.
Focus on the details that change material purchasing, the machining route and finished-part acceptance.
Review access early
Deep slots, long bores and small internal radii can dominate the machining route. Highlight the functional radius requirement and any permitted relief geometry.
Tie records to the supplied lot
List the requested chemistry, mechanical or heat-treatment documents. A manufacturer bulletin is a reference for the alloy, not a material certificate for your delivery.
ORDER DETAILS

Are Inconel, Monel and Invar interchangeable names?
No. They cover different alloy families and property priorities. Retain the exact alloy number and the applicable product standard when requesting a quotation.
Can I quote 718 without stating its condition?
The drawing can begin the discussion, but the supplied condition and any required final treatment must be clarified to define the machining route and price scope.
