Pangkalahatang-ideya ng Spring steel round bar
Ang spring steel round bar ay angkop para sa iba't ibang uri ng spring application kabilang ang mga flat spring, clutches, kutsilyo, doctor blades, saw blades, agricultural tool, wood cutting saws, shims, kutsilyo, blades, shims, washers, masonry tool. Kapag nag-iiba ang mga temperatura ng heat treating EN42, kabilang ang rate ng pag-init, paglamig at pagbababad, atbp. dahil sa mga salik gaya ng hugis at sukat ng bawat bahagi. Ang iba pang mga pagsasaalang-alang sa panahon ng proseso ng heat treatment ay kinabibilangan ng uri ng furnace, quenching medium, at workpiece transfer facility. Mangyaring kumonsulta sa iyong tagapagbigay ng paggamot sa init para sa buong gabay sa paggamot sa init ng mga spring steel.
