Ibha Yensimbi Engagqwali engu-403
Incazelo emfushane:
Insimbi engagqwali engu-403 iyinsimbi engagqwali ye-martensitic enokuqukethwe okuphezulu kwekhabhoni kanye nokumelana nokugqwala okulinganiselwe.
Ibha eyindilinga engu-403 yokuhlola i-UT:
I-403 iyinsimbi ye-martensitic, futhi izakhiwo zayo zingathonywa kakhulu ukwelashwa kokushisa. Ingaqiniswa futhi iqiniswe ukuze kufezwe izakhiwo ezifunwayo zemishini. Ngenkathi insimbi engagqwali ye-403 inikeza ukumelana nokugqwala okulinganiselwe, ayimelani nokugqwala njengezinsimbi ezingagqwali ze-austenitic ezifana ne-304 noma i-316. Ifaneleka kangcono ukusetshenziswa ezindaweni ezithambile ezigqwala. Le nsimbi ingafinyelela amazinga aphezulu obulukhuni ngemva kokwelashwa kokushisa, okwenza ifaneleke ukusetshenziswa lapho ubulukhuni nokumelana nokuguguleka kubalulekile khona. Inokushibilika okufanele, kodwa ukushisa kusengaphambili kuvame ukudingeka, futhi ukwelashwa kokushisa ngemva kokushibilika kungadingeka ukuze kuncishiswe ingozi yokuqhekeka.

Ukupakisha kwe-SAKY STEEL'S:
1. Ukupakisha kubaluleke kakhulu ikakhulukazi uma kuthunyelwa kwamanye amazwe lapho imithwalo idlula khona ngemigudu eyahlukene ukuze ifike endaweni yokugcina, ngakho-ke sikhathalela kakhulu ukupakisha.
2. I-Saky Steel ipakisha izimpahla zethu ngezindlela eziningi ngokusekelwe emikhiqizweni. Sipakisha imikhiqizo yethu ngezindlela eziningi, njengokuthi,
