iStainless Steel 347 1.4550
Olu cwecwe lwedatha lusebenza kwintsimbi engatyiwa 347 / 1.4550 eshushu kwaye ibanda ishiti eqengqelekayo, imicu kunye nemivalo, iimveliso ezigqityiweyo, iintonga kunye namacandelo kunye neetyhubhu zentsimbi ezingenamthungo nezidityanisiweyo ukulungiselela iinjongo zobunjineli ngoomatshini kunye nobunjineli ngokubanzi.
Isicelo
Kwiindawo zokwakha ekufuneka zixhathise ukuya kuthi ga kwi-1050 ° C kwaye zifakwe kakhulu kwimpembelelo yeegesi zesulfure, ngakumbi ngaphezulu kwe-900 ° C, ziphantsi kakhulu.
