MACPRIME® is a special-bar quality steel bar precut to customers' exact dimensional specifications. MACPRIME® gives forgers, machining facilities and cold formers numerous advantages, including easy unload, reduced storage.
Typical Grades: MACPRIME® steel bars can be produced from any grade within MACPRIME®’s capability including quench & tempered steels
MACPRIME® Sizes: Diameters from 5⁄8” to 61⁄16”. Lengths from 3⁄8” to 60”
MACPRIME® Tolerances: Length tolerances as low as ± 0.005”. Gram weight tolerances as low as ± 2 grams (when using MACPLUS®). Perpendicularity tolerances as low as 0.006”. TIR tolerances as low as 0.003”.
Combine the advantages MACPLUS® Cold Finished Bars with MACPRIME® First Operation Blanks and you get:
Defect-Free Surface: Better Machinability.
Decarb-Free Surface: Length, gram weight and perpendicularity tolerances to meet your specif cations 100% of the time.
Scale-Free Surface: No shear or saw cut burrs.
Low Residual Stress: No end distortion.
Diameter, TIR and out-of-round tolerances to meet your specifications 100% of the time: Guaranteed trouble-free product.
