Precipitation hardening stainless steel, kang disebut PH Steel, nuduhake jinisbaja tahan karatsing nambahake macem-macem jinis lan jumlah unsur penguat, lan macem-macem jinis lan jumlah karbida, nitrida, karbonitrida lan senyawa intermetal diencerake liwat proses pengerasan udan. Precipitation hardening stainless steel ora mung nduweni kekuatan dhuwur, nanging uga nduweni kateguhan apik lan resistance karat. The udan hardening stainless steel bisa matak ing kitapengecoran pengecoran investasimiturut gambar, syarat lan kahanan panggunaan.
Miturut isi unsur alloy utama ing udan hardening stainless steel lan ditambahake unsur hardening, udan hardnening stainless steel bisa dipérang dadi papat kategori ing ngisor iki:
(1)Baja Tahan Karat Pengerasan Presipitasi Martensit. Umume ngemot karbon kurang saka 0,1%. Nguatake kanthi nambah unsur hardening (tembaga, aluminium, titanium lan aluminium, lan sapiturute) kanggo nggawe kekurangan kekuatan. Isi kromium umume luwih dhuwur tinimbang 17%, lan jumlah nikel sing cocog ditambahake kanggo nambah resistensi karat.
(2)Maraging Precipitation Hardening Stainless Steel, karo isi karbon ora luwih saka 0,03% kanggo mesthekake kateguhan, resistance karat, weldability lan workability saka matriks martensite, lan 12% kromium kanggo njamin resistance karat. Kajaba iku, kobalt unsur alloy ditambahake kanggo nambah efek perawatan panas saka baja.
(3)Semi-Austenitic Precipitation Hardening Stainless Steel, yaiku, stainless steel hardening presipitasi transisi, ngemot ora kurang saka 12% kromium. Isine kurang karbon, lan aluminium minangka unsur hardening udan utama. Baja tahan karat pengerasan presipitasi iki nduweni kinerja sakabehe sing luwih apik tinimbang baja tahan karat pengerasan presipitasi martensitik.
(4)Baja Tahan Karat Pengerasan Presipitasi Austenitikpunika stainless steel karo struktur austenite stabil ing loro negara quenched lan tuwa. Isi nikel lan manganese dhuwur, lan isi kromium luwih saka 13% kanggo mesthekake resistance karat apik lan resistance oksidasi. Ing wektu sing padha, baja tahan karat pengerasan udan austenitik biasane nambahake titanium, aluminium, vanadium utawa fosfor minangka unsur pengerasan udan, lan nambahake boron, vanadium, nitrogen lan unsur liyane kanggo entuk sifat komprehensif sing apik.
Precipitation hardening stainless steel digunakake digunakake ing industri maju. Contone, baja tahan karat hardening udan khas 17-4PH bisa digunakake kanggo nggawe struktur ing ngisor 370 ° C sing mbutuhake resistensi karat, resistensi nyandhang, lan kekuatan dhuwur.
