Product Description

scm440 peeled or turned steel round bar

scm440 steel is a Chromium-Molybdenum through-hardening steel of medium hardenability. It is a general purpose high-tensile steel with medium strength level and good impact properties. scm440 steel is in JIS standard, the similar materials in different standard is GB 42CrMo or 42CrMoA, AISI 4140, SAE 4140, ASTM 4140, DIN 1.7225, DIN 42CrMo4, AS 4140, 42CD etc. Depending on various applications, scm440 steel are used after different processing such as cold drawing, peeling, turning, annealing, normalizing, quencheding and tempering etc. Our company has our own factory with full sets of production facilities to supply these delivery conditions steel bar such as scm440 hot rolled steel bar, scm440 cold drawn steel bar, scm440 peeled steel bar, scm440 turned steel bar, polished and ground scm440 steel bright bar, scm440 annealed steel bar, scm440 normalized steel bar, scm440 quenched and tempered steel bar. We can also supply other services such as cutting, straightening, blasting, chamfering, drilling, thread rolling etc.


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
