Qib 440B Stainless Hlau - Nruab Nrab -Carbon 440 Variant Rau Kev Txhim Kho Hnav Ua Haujlwm

Txheej txheem cej luam

Qib 440B yog qhov nruab nrab -carbon variant ntawm 440 tsev neeg, muab siab dua hnav tsis kam tshaj 440A thaum tuav zoo toughness. Nws muaj 0.75-0.95% carbon thiab 16.0-18.0% chromium, nrog molybdenum ntxiv los txhim kho corrosion kuj thiab hardenability. Tsis zoo li 440A, Qib 440B ua tiav qhov tawv tawv dua tom qab kev kho cua sov (txog 58 HRC), ua rau nws tsim nyog rau cov ntawv thov uas yuav tsum tau hnav tsis kam. Nws yog hlau nplaum thiab muaj kev ua haujlwm zoo thaum annealed, txawm hais tias nws yuav tsum tau ceev faj txog kev kho cua sov ntau dua li 440A kom tsis txhob brittleness.

Core Zoo

Siab hnav tsis kam tshaj 440A; zoo toughness thiab corrosion kuj; cua sov- kho tau kom siab hardness; Sib nqus; zoo machinability nyob rau hauv lub xeev annealed; zoo heev ntug tuav rau hnyav- cov cuab yeej txiav.

Daim ntawv thov

Hnyav- riam, bearings, iav, li qub, thiab precision Cheebtsam uas yuav tsum tau txhim khu kev hnav tsis kam thiab kev tiv thaiv corrosion nruab nrab.
