EN 10084 18CrNiMo7-6 round bars
EN 10084 18CrNiMo7-6 is a Chrome – Nickel – Moly carburising steel, generally supplied annealed to HB 229 max. Carburised and heat treated it develops a hard wear resistant case of about Rc 60-63 and a tough strong core with a typical tensile strength range of 900-1300 MPa, in small to fairly large sections.
EN 10084 18CrNiMo7-6 is mainly used for Heavy-duty arbors, bushings, bearings, gears, shafts, sprockets, wear pins etc. or can be used uncarburised with suitable heat treatment for high tensile applications.
EN 10084 18CrNiMo7-6 can be produced into hot rolled round bars and square bars, cold-drawing bars,forged bars. We henan bebon can supply 18CrNiMo7-6 all of shapes.
According to the market needs, henan bebon supply the oversea markets for 18CrNiMo7-6 hot rolled round bars OD 6mm -80 mm and 18CrNiMo7-6 forged round bars OD 80 mm - 1200 mm, also 18CrNiMo7-6 forged square bars OD 100- 1200 mm. The OD tolerance is about 0-3 mm and length tolerance is about 0-20 mm.
18CrNiMo7-6 round bars are usually produced under the followed procedures: EAF arc furnace + LF purify affinage + VDF + ingot steel(bottom gating /argon) + forged + annealing + black polishing (turnery) + Sep 1921-C/c,D/d,E/e UT test + smooth edges with sawing .
