UNS S44004 - Siab-Carbon 440-Series Martensitic Alloy Rau Kev Hnav Siab Tshaj Plaws

Txheej txheem cej luam

UNS S44004 yog qhov siab -carbon variant ntawm 440-series (raws li AISI 440C), xa qhov siab tshaj plaws hnav tsis kam thiab hardness ntawm 440-series qib. Nrog 0.95-1.20% carbon thiab 16.0-18.0% chromium, nws ua tiav qhov hardness ntawm 58-60 HRC tom qab kev kho cua sov, ua rau nws zoo tagnrho rau cov ntawv thov uas yuav tsum tau hnav tsis kam thiab ntug tuav. Nws muaj molybdenum los txhim kho corrosion kuj thiab hardenability, thiab yog sib nqus nrog zoo machinability thaum annealed. Piv rau UNS S44002 thiab S44003, nws yog qhov yooj yim dua rau brittleness thiab yuav tsum tau ceev faj txog kev kho cua sov, tab sis muaj kev hnav tsis sib xws rau cov ntawv thov tseem ceeb.
