Product Description

scm440 peeled or turned steel round bar


scm440 peeled and turned steel round bar is a kind of machining used to remove the imperfections on the hot rolled bars surface such as the scales and decarburized layers. It gets more precision diameter tolerance, bright surface and good straightness after peeling or turning. If grinding or polishing is added, scm440 turned, ground and polished precision steel bar can be directly used in CNC machines to produce shafts and components such as crankshafts, high-speed motor shafts, axle shafts, pup shafts etc.

 

scm440 turned ground and polished steel bar we supply includes following advantages:

Consistent mechanical properties

Deep mechanical properties (from surface to the center according to your requirement)

Even hardness on the whole bars/Tougher and Increased strength

No brittle, UT testing/Precision size tolerance/Good straightness

Good Roughness/Professional technical service/Extra services such as cutting, straightening, drilling, chamfering, thread rolling

Competitive price/Fast delivery/Free samples/Trial production and testing
