4140 peeled or turned steel round bar
4140 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.
Steel bar peeling or turning 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.
4140 turned or peeled 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/Competitive price/Fast delivery
