Common Custom 455 Stainless Steel Specifications & Heat Treatment
| Grade | Custom 455 Stainless Steel |
|---|---|
| Common bar standards | ASTM A564 for correctly designated Custom 455 (UNS S45500); verify any applicable AMS standard. |
| Heat treatment / supply condition | Solution-treated then precipitation aged in specified H condition, per supplier qualified treatment. |
| Precision finishing | Specify finished OD and limits, rod length and quantity, straightness, roughness, hardness, and required documents. |
Do not assume a particular H condition without the design standard.
Typical standards and conditions are purchasing references only, not a stock/certification or in-house heat-treat promise. Confirm supplied product form, condition and any externally coordinated thermal treatment in the written RFQ.
PRECIPITATION-HARDENING STAINLESS • MATERIAL GRADE BUYING GUIDE
Custom 455 Stainless Steel precision ground rod stock — Custom 455 is a precipitation-hardening stainless alloy developed for specified mechanical performance in qualified components.
Custom 455 Stainless Steel Rod Material and Specification
For this grade, the important question is not simply whether a rod is offered as “precision ground.” Buyers should define the material identity, the intended delivery condition and the acceptance requirements. Order the precise alloy trademark/designation, UNS number and required product specification.
Condition and Processing Considerations
Specify annealed or age-hardened condition and the required strength/hardness evidence.
Where Custom 455 Stainless Steel Rod Stock May Be Considered
Qualified instrument, aerospace and specialized mechanical components.
The required rod diameter and finish must be consistent with the final manufacturing process. Ground stock may be appropriate for selected machining or shaft-preparation workflows, but the final component design determines whether the grade, microstructure and surface condition are suitable.
Custom 455 Stainless Steel Centerless Ground & TG&P Bar Options
Custom 455 Stainless Steel Centerless Ground Bar
For Custom 455 Stainless Steel centerless ground rods and bars, state the precipitation-hardening condition and target mechanical properties before specifying the grinding sequence. See centerless grinding services for the OD finishing route.
Custom 455 Stainless Steel TG&P / Turned, Ground & Polished
If your RFQ calls for Custom 455 Stainless Steel TG&P (TGP) or turned, ground and polished bar, Custom 455 TG&P inquiries must include heat treatment, OD and surface finish and require availability verification. Learn about shafting and bar sourcing and surface polishing.
Centerless-ground material is not necessarily TG&P. Grade, supplied condition, turning requirements, final OD, straightness, finish and availability are confirmed by quotation. Request a quote →
What to Verify Before Ordering
Avoid substituting 17-4 PH or 15-5 PH merely on strength claims; actual certified mechanical and corrosion needs determine suitability.
- Finished outside diameter: state the size and exact upper/lower OD limits, not just a nominal inch or millimeter dimension.
- Lengths and quantity: give the bar length or cut length, end requirements, number of pieces and requested shipment schedule.
- Material condition: include the specified grade, applicable product standard, heat-treatment or hardness state and certification requirements.
- Inspection: specify straightness with a measurement span, roundness, surface roughness and traceability where your application calls for them.
Supply, OD Grinding and Quote Requirements
Precision Ground Rods provides grade-specific sourcing and precision bar processing quotations. Depending on the grade, condition, diameter and length, material supply may be combined with outside-diameter grinding, straightening, polishing, cutting and packaging. These capabilities are evaluated for each RFQ; this page does not promise a standard stocked size or a universal grinder tolerance.
For a useful Custom 455 Stainless Steel inquiry, attach the purchase specification and drawing and indicate whether you need finished ground rod stock or want customer-owned stock processed. Include the quantity, delivery destination and inspection plan so the quotation can address all relevant requirements.
Browse all rod material grades to compare other chemistries and product forms. Verify any material substitution with engineering.
General purchasing information, not a certified material test report or an approval for regulated service. All material properties, dimensions and certificates must be confirmed in the written quotation.
