1144 Stressproof-Type Steel Round Bar — Technical Purchasing Guide

Grade, condition and processing reference information
Item Reference / purchasing detail
Material/product 1144 Stressproof-Type Steel Round Bar
Grade identity and purchase standard SAE/AISI 1144; proprietary STRESSPROOF specifications where actually certified
Delivery or treatment condition Require the manufacturer-specific cold-drawn/stress-relieved state or separate specified condition
Typical applications Shafts, precision pins and general heavy-duty machined parts
Selection concern Do not advertise generic 1144 as STRESSPROOF without the qualifying producer requirements and certificates.
Mozaic processing Precision round-bar grinding, straightening, cutting, chamfering and packing when feasible

Technical overview, not a certified composition or mechanical-property report. Confirm grade designation, product standard, required condition and heat-lot documentation for every order.

Why Material Grade and Condition Matter

Do not advertise generic 1144 as STRESSPROOF without the qualifying producer requirements and certificates. Representative components include shafts, precision pins and general heavy-duty machined parts. Different grades can share a broad alloy family while requiring distinct finishing, inspection or material qualification. Procurement and engineering should agree on the supplied condition and part performance before accepting substitutions.

Precision Bar Supply and Processing

Mozaic Precision Metals offers project-specific centerless grinding, bar straightening, polishing, saw cutting, chamfering and packaging. Our quoting process considers material condition, diameter, length and the required final surface. Diameter tolerance, straightness and roughness should be specified and inspected separately.
