Tso lus
Thaum xaiv cov cua sov-cov hlau tsis muaj zog rau cov hlab ntsha siab, cov khoom siv hluav taws xob sib txawv, lossis siab - cov kav dej kub, ob hom stabilized austenitic qib-1.4550 (AISI 347) thiab 1.4541 (AISI 321)-feem ntau tshwm sim hauv cov npe khoom. Txawm hais tias ob qib yog tsim los tiv thaiv carbide nag lossis daus thaum vuam, lawv sib txawv hauv kev ruaj khov, kev ua tau zoo, thiab kev siv tau zoo.
1.4550 stainless hlau (AISI 347 / X6CrNiNb18-10) yog dab tsi?
1.4550 yog niobium-stabilized austenitic stainless hlau tsim tshwj xeeb rau kev txhim kho siab - kub corrosion kuj thiab vuam stability. Niobium (Nb) cov ntaub ntawv ruaj khov carbides, tiv thaiv intergranular corrosion tom qab vuam los yog ntev raug rau qhov kub thiab txias ntawm 450-850 degree. Nws yog feem ntau siv hauv cov khoom siv hluav taws xob sib hloov, siab -kub kav, cov cuab yeej siv tshuaj, cov tshuab tso pa tawm, thiab cov khoom siv thermal cycling.
1.4541 stainless hlau (AISI 321 / X6CrNiTi18-10) yog dab tsi?
1.4541 yog titanium-stabilized stainless hlau dav siv nyob rau hauv tsheb, aerospace, thiab dav dav -kub siv. Titanium kuj muab kev ruaj khov, tab sis nws cov nyhuv yog me ntsis zoo dua li niobium hauv kev xav tau thermal cycling ib puag ncig. Nws yog feem ntau siv nyob rau hauv automotive tso manifolds, cub tawg Cheebtsam, siab hlab ntsha, boilers, thiab welded lug.
