C71500 siv
C71500 yog dav siv nyob rau hauv marine thiab tshuaj ua lag luam. Nws zoo heev corrosion kuj yog zoo tagnrho rau seawater txias tshuab thiab marine daim ntaub ntawv. Nws lub zog siab thiab hardness ua rau nws zoo tagnrho rau lub cev valve, lub cev twj tso kua mis, thiab lwm yam kev siv tshuab siab. C71500 kuj tseem siv rau hauv cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab lwm yam kev siv uas xav tau kev hloov pauv kub zoo heev thiab tiv thaiv fouling.
C71500 Hardness
C71500 muaj ib tug zoo hardness txog 120 HV, siab tshaj tooj liab ntshiab. Nws cov hardness siab ua rau nws tiv taus hnav thiab deformation, ua rau nws zoo tagnrho rau kev siv zog siab.
C71500 Kev kho cua sov
C71500 tsis xav tau kev kho cua sov rau kev txhim kho lub zog. Txawm li cas los xij, nws tuaj yeem raug muab tshem tawm kom txo kev ntxhov siab thiab txhim kho machinability. Thaum lub sij hawm annealing, lub alloy yog rhuab mus rau ib tug kub ntawm 620 thiab 760 degree, txias maj mam nyob rau hauv huab cua los yog dej, thiab ces tempered nyob rau hauv chav tsev kub.
C71500 vuam
C71500 tuaj yeem nkag tau yooj yim welded siv ntau txoj kev, suav nrog roj tungsten arc vuam thiab roj hlau arc vuam. Nws yog ib qho tseem ceeb los ntxuav qhov saum npoo thiab siv cov hlau ua kom haum kom tsis txhob muaj porosity thiab tawg.
C71500 Corrosion Resistance
C71500 nthuav tawm zoo heev corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv seawater thiab lwm yam dej qab zib ib puag ncig. Nws muaj kev tiv thaiv zoo rau crevice corrosion, kev nyuaj siab corrosion cracking, thiab pitting. Nws cov corrosion kuj ua rau nws haum rau marine daim ntaub ntawv, tshuaj ua industries, thiab roj thiab roj kev tshawb fawb.
