Common 1144 Stressproof-Type Steel Specifications & Heat-Treatment Conditions
| Material | 1144 Stressproof-Type Steel |
|---|---|
| Common material standards | ASTM A108 or producer-specific Stressproof®-type certification; SAE 1144 chemistry alone is insufficient for Stressproof® branding. |
| Supply / heat treatment | Cold-drawn and stress-relieved condition is distinct from general annealed/Q&T 1144. |
| Required rod dimensions | Final outside diameter and limits; length and quantity; straightness and finish requirements if specified. |
Only claim proprietary Stressproof® when the original mill product certification supports it.
References are not stock guarantees. Material standards, certification, outsourced heat treatment and final grinding are confirmed by written quote, not assumed from grade name alone.
CARBON & ALLOY STEEL / PRECISION ROD BUYING GUIDE
Cold-drawn and stress-relieved 1144-type bar used for controlled dimensional behavior and machining.
1144 Stressproof-Type Steel Rod Purchasing Specifications
SAE/AISI 1144; verify whether a specific branded Stressproof product or equivalent properties are required. A purchasing description must also identify whether the order is for raw stock, finished ground bar, or grinding of customer-owned stock. Finished outside diameter is separate from the material grade and is verified by an agreed inspection method.
Condition, Machining and Finishing
Specify proprietary processing/hardness and any stress-relief requirement rather than assuming standard 1144 is equivalent.
Grinding allowance and wheel selection depend on incoming bar diameter, condition, length and straightness. If the bar will undergo subsequent heat treatment or plating, coordinate processing sequence and the final diameter acceptance with your engineer.
Typical 1144 Stressproof-Type Steel Applications
Machined shafts, axles, studs and precision machine components.
End-use suitability depends on the component design, not merely a material name or a polished surface. Drawings should identify functional dimensional limits and related mechanical-property requirements.
Material Selection and Substitution Cautions
Trade names and mechanical properties should be verified by mill test documentation; different products may have different acceptance limits.
Precision Rod RFQ Checklist
1144 Stressproof-Type Steel Centerless Ground & TG&P Bar Options
1144 Stressproof-Type Steel Centerless Ground Bar
For 1144 Stressproof-Type Steel centerless ground rod or bar, 1144 chemistry does not automatically guarantee proprietary stress-relieved properties; confirm mechanical condition before grinding. Review precision centerless grinding when specifying your finished outside diameter.
1144 Stressproof-Type Steel TG&P / Turned, Ground & Polished
When a drawing calls for 1144 Stressproof-Type Steel TG&P (TGP) or turned, ground and polished rod, for 1144 TG&P shafting, state whether a branded stress-relieved product is specified and how final dimensions are inspected. Explore bar supply and surface finishing.
Centerless-ground bar and TG&P shafting are not synonymous. Verify material condition, full route, OD tolerance, straightness, surface finish and available lengths against the RFQ. Request pricing →
- Material: grade, applicable ASTM/AMS or mill specification, supply condition and certifications.
- Size: finished outside diameter, explicit upper/lower tolerance limits and incoming OD if grinding supplied stock.
- Length and volume: full-bar or cut lengths, cut tolerance, pieces/bars/pounds and shipping destination.
- Acceptance: straightness span/method, roughness, roundness, hardness and lot traceability if required.
