Kev piav qhia
Martensitic stainless hlau resistant rau corrosion. 1.2085 steel qhia qhov zoo tshaj plaws corrosion kuj nyob rau hauv hardened mob nrog ib tug nto polished muab ib daim iav finisih. Cov Khoom: Hlau nplaum hlau nplaum zoo txhua yam ua haujlwm thiab toughness, zoo heev rau kev tsim khoom ntawm cov khoom uas yuav tsum tau tiv thaiv cov yas hnyav, cov cuab yeej siv tau zoo ua tsaug rau nws cov ntsiab lus sulfur, haum rau kev ua haujlwm hauv huab cua ntub thiab noo noo, haum rau polishing, hnav thiab corrosion pov thawj, thiab ruaj khov dimensionally thaum kho cua sov.
Daim ntawv thov
Txhua yam ntawm cov cuab yeej txiav - tuag thiab tuag-thaiv hauv kev lag luam yas xws li PVC, riam, txiav, cov cuab yeej phais, pwm rau cov khoom siv yas, nrog rau cov cuab yeej phais thiab ntsuas ntsuas.

Mos Annealing
Kub rau 760-780oC, txias maj mam. Qhov no yuav tsim qhov siab tshaj plaws Brinell hardness ntawm 230.
Hardening
Preheating: 800oC. Harden los ntawm qhov kub ntawm 1000-1050oC ua raws li cov roj, los yog polymer txias da dej. Hardness tom qab quenching yog 51-55 HRC.
Tempering
Tempering kub: 150-200oC.
Forging
Kub tsim kub: 1050-850oC, qeeb txias.
Machineability
Zoo heev machinability.
