Qib 440 Stainless Hlau

Kev piav qhia

Qib 440 yog qib siab -carbon martensitic stainless hlau, muaj npe nrov rau nws qhov tshwj xeeb hardness, hnav tsis kam, thiab nruab nrab corrosion kuj. Nws muaj nyob rau hauv peb qib - qib (440A, 440B, 440C) nrog cov pa roj carbon sib txawv, nrog 440C muaj cov ntsiab lus siab tshaj carbon (0.95-1.20%) thiab yog li qhov siab tshaj plaws hardness thiab hnav tsis kam. Tag nrho 440 sub- qib muaj 16.0-18.0% chromium, muab kev tiv thaiv zoo corrosion nyob rau hauv ib puag ncig me me, txawm tias tsis siab npaum li qib austenitic xws li 304 lossis 316. 440 yog cov hlau nplaum thiab tuaj yeem ua kom sov-kho kom ua tiav qhov hnyav hnyav (txog 60 HRC), ua rau cov cuab yeej siv tau zoo, xws li kev txiav thiab kev siv lub tswv yim li qub. Nws muaj qhov txwv formability thiab weldability vim nws cov ntsiab lus carbon siab, tab sis nws tuaj yeem siv rau hauv lub xeev annealed . 440 yog siv dav hauv cov ntawv thov kev ua haujlwm siab uas hnav tsis kam yog qhov tseem ceeb.

Qhov zoo

Exceptional hardness thiab hnav tsis kam (siab tshaj plaws ntawm cov qib martensitic); zoo corrosion kuj nyob rau hauv ib puag ncig me me; Sib nqus; tshav kub- kho tau kom ua tiav qhov tawv tawv; haum rau siab - hnav daim ntaub ntawv.

Daim ntawv thov

Cov kabmob, cov cuab yeej txiav, riam, hniav, li qub, lub zog, cov cuab yeej phais, thiab cov khoom ua haujlwm siab - yuav tsum tau hnav zoo dua.
