34CrNiMo6 quenched & tempered steel round bar
34CrNiMo6 steel is one kind of nickel chromium molybdenum alloy steel know for it's toughness and ti's ability to attach high strength after heat treatment. We can supply 34CrNiMo6 turned or peeled steel bar, turned steel bar, peeled steel bar, polished steel bar and centerless ground bar. All of the bars are Bright Steel Bar with good surface quality. Is it similar to SCM439 steel round bar, EN24 steel round bar and 4340 steel round bar
Quenching and Tempering, abbreviated as Q&T is a king of processing that strengthen or harden steel bars by heating the materials and then cooling in water, oil or other liquid medium, that rapidly the change from austenite to perlite to get the proper properties for various usage. The quenched & tempered steel bar materials are usually with carbon from 0.30% - 0.60%, it is widely used as merchant bars in components of various machines.
34CrNiMo6 material quenched and tempered q&t steel bar we supply includes following advangtages:
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
