STS440B - Nruab nrab-Carbon 440-Series Martensitic Alloy Rau Kev Txhim Kho Kev Ua Haujlwm Zoo

Txheej txheem cej luam

STS440B yog qhov nruab nrab -carbon variant ntawm STS 440-series, muab kev hnav siab dua li STS440A thaum tuav zoo toughness. Nrog 0.75-0.95% carbon thiab 16.00-18.00% chromium, nws ua tiav qhov hardness ntawm 56-58 HRC tom qab kev kho cua sov, ua rau nws tsim nyog rau cov ntawv thov uas yuav tsum tau siv zog ntxiv. Nws muaj molybdenum los txhim kho corrosion kuj thiab hardenability, thiab yog sib nqus nrog zoo machinability thaum annealed. Piv rau STS440A, nws yuav tsum tau ua tib zoo kho cua sov kom tsis txhob brittleness, tab sis muab kev hnav zoo tshaj plaws rau kev siv hnyav.

Core Zoo

Siab hnav tsis kam tshaj STS440A; 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; haum rau hnav- siv hnyav; hardenability zoo dua STS440A.

Daim ntawv thov

Hnyav- rab riam, bearings, iav, valve Cheebtsam, cov cuab yeej phais, cov cuab yeej txiav, thiab cov khoom precision uas yuav tsum tau ua kom muaj kev tiv thaiv zoo thiab kev tiv thaiv corrosion.
