Yog 1.4408 thiab 1.4541 sib pauv tau?
Tsis ncaj qha.1.4408yog melted, thaum1.4541Nws yog ua haujlwm. Lawv muaj cov txheej txheem sib txawv thiab cov kev coj ua tshuab.
1.4408 thiab 1.4541, uas muaj kev txhim kho corrosion zoo dua?
1.4541Nws muaj cov corrosion zoo dua feem ntau, tshwj xeeb hauv cov ntawv thov welded, vim nws cov kev ruaj khov nrog titanium.1.4408yog ib tug cam khwb cia steel hlau muaj molybdenum, uas muab nws zoo tsis kam rau cov corrosion, tab sis lub titranium stabilization corrosion, tshwj xeeb yog tom qab vuam lossis raug rau qhov kub.
1.4408 thiab 1.4541, qib twg yog qhov zoo tshaj plaws rau vuam?
Cov degree1.4541Nws yog feem ntau zoo dua rau cov vuam ntau dua li 1.4408 vim nws cov titgium stabilization, uas tiv thaiv kev txhim kho corrosion tom qab siv rau cov ntawv thov kub siab. Txawm yog1.4408Nws muaj qhov zoo tshaj plaws weldability ntawm chav sov, nws cov ntsiab lus carbon ntau dua ua rau nws raug ntau dua rau kev xeb tom qab vuam yog tsis kho kom zoo.
Tau 1.4408 tau siv rau hauv cov ntawv thov kub siab?
Nws yog ua tau, tab sis1.4541Nws yog qhov ruaj khov tshaj 800 degrees, ua rau nws nyiam kev tso pa tawm thiab cov ntawv thov thermal.
