Product Description

42CrMo4 peeled or turned Steel Round Bar

42CrMo4 steel is one kind of Chromium-Molybdenum steel in DIN standard same to DIN 1.7225. The 42CrMo4 equivament steel includes scm440, Aisi 4140 , sae 4140, astm 4140,as 4140 and 42CrMo in GB standard. 42CrMo4 steel is one kind of high tensile steel material with medium strength level, good impact properties and hardenabilities. This steel material is suaully used after quenching and tempering. As a processing factory, we can do cold drawing, peeling, cenerless grinding and polishing. So except 42CrMo4 hot rolled steel bars, we can also supply you 42CrMo4 hot rolled steel Round Bar , 42CrMo4 Cold Drawn Steel Round Bar, 42CrMo4 peeled steel round bar, 42CrMo4 centerless ground and polished Bright Steel Round Bar. We can also produce 42CrMo4 annealed steel round bar, 42CrMo4 normalized steel round bar, 42CrMo4 Quenched And Tempered Steel Bar ( 42CrMo4 qt steel bar, 42CrMo4+ qt steel bar, 42CrMo4 Q&T steel bar).

42CrMo4 Peeled Or Turned Steel Bar is a kind of machining used to remove the imperfections on the hot rolled bars surface. It can also get more precision diameter tolerance and bright surface after peeling or turning. If grinding or polishing is added, the steel bars will be have very good surface roughness which can be directly used to produce components. 42CrMo4 turned, ground and polished precision shafting is produce by 42CrMo4 cold drawn or hot roll steel bar to get precision dimension and better straightness in the production of shafts. The straightness is quite important to shafting CNC machining. 42CrMo4 turned Ground And Polished Steel Bar is used to produce crankshafts, high-speed motor shafts, axle shafts, pup shafts, etc.

42CrMo4 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

5. Our products inspection:

Quality is the most important. With complete testing equipment, we pays much more attention to the products quality. Not only the steel bar surface qualtity like diameter tolerance, length tolerance, surface roughness, decarbornization, straightness, we also do microsture and ultrosonic testing to guarantee the inner quality. In heat treatment, we do frequenet testing on the mechanical properties to keep 100% quality approved.


4. Our products package:

Product is most important, the protection package is also very important. We can customize different package according to your products level and requirements.


Our aim is to supply you steel solution to decrease your cost and increase your value. Except the raw material such as hot rolled steel bar, cold drawn steel round bar, peeled steel round bar, turned steel round bar and the heat treated steel bar, steel bright steel, we can also do more processing service such as cutting, drilling, chamfering, forging, thread rolling etc. Any demands or questions, we welcome you to communicate with us.
