Qhov txawv ntawm 1.4301 thiab 1.4401 teel yeeb nkab yog dab tsi?
Tso lus
1.4301 stainless hlau, tseem hu ua AISI 304 lossis X5CrNi18-10, yog austenitic stainless hlau. Nws muaj kev tiv thaiv zoo corrosion, tshwj xeeb tshaj yog nyob rau hauv oxidizing ib puag ncig, nrog rau zoo machinability thiab weldability. Cov hlau tsis muaj steel no feem ntau siv los tsim cov khoom noj khoom haus, khoom siv kho mob, thiab cov khoom siv tshuaj ua haujlwm
