Product Description
4140 cold drawn steel flat 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. We can supply 4140 hot rolled steel bar and 4140 cold drawn steel bar. Besides we can also produce 4140 heat treated steel bars such as 4140 annealed steel bar, 4140 normalized steel bar, 4140 quenched & tempered steel bar. We produce all kinds of shapes steel bars such as 4140 steel round bar, 4140 square steel bar, 4140 flat steel bar and 4140 hexagonal steel bar. 4140 cold drawn steel flat bar we produce is usually used in automotive and machinery industry.
4140 cold drawn 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
