Luv hauj lwm:

H13 Tool Steel is chromium hot work tool steels which are widely used in hot and cold work tooling applications. H13 tool steel is classified as group H steels by the AISI classification system. This series of steels start from H1 to H19. AISI H-13 tool steel is characterized by: Good resistance to abrasion at both low and high temperatures High level of toughness and ductility Uniform and high level of machinability and polishability Good high-temperature strength and resistance to t...

    H13 Tool Steel yog chromium kub ua hauj lwm cov cuab tam steels uas yog lug siv nyob rau hauv kub thiab txias ua hauj lwm Tooling daim ntaub ntawv. H13 lub cuab tam steelyog dej num raws li cov pab pawg neeg H steels los ntawm cov AISI kev faib system. Qhov no series ntawm steels pib los ntawm H1 rau H19.

    AISI H-13 lub cuab tam steel yog yus muaj los ntawm:

    • Zoo kuj mus puas rau ob tsawg tsawg thiab siab kub

    • High theem ntawm toughness thiab ductility

    • Uniform thiab theem siab ntawm machinability thiab polishability

    • Zoo high-kub zog thiab kuj mus thermal qaug zog

    • Rau yav tom ntej los ntawm-hardening zog

    • Heev tsawg distortion thaum lub sij hawm hardening

    Nyob rau hauv
    steel H13, lub molybdenum thiab vanadium ua raws li ntxiv dag zog rau cov neeg ua hauj. Lub
    chromium cov ntsiab lus pab tuag steel H-13 los kom tiv thaiv softening thaum siv
    thaum muaj kev kub kub. H-13 tuag steels muaj ib qho zoo heev ua ke nrog ntawm
    poob siab thiab puas kam, thiab possesses zoo liab hardness. Nws yog
    peev xwm ntawm tiv sai txias thiab resists ntxov ntxov thaum tshav kub kub
    checking. Tool Steel H13 muaj zoo machinability, zoo weldability, zoo
    ductility, thiab muaj peev xwm yuav tsim nyob rau los ntawm cov pa txhais tau tias.

    Vim H13
    lub cuab tam steel zoo heev ua ke nrog ntawm siab toughness thiab qaug zog
    kuj, AISI H13 kub ua hauj lwm cov cuab tam steel yog siv ntau tshaj li lwm yam
    cuab yeej steel nyob rau hauv Tooling daim ntaub ntawv.

    • hardening

    H13
    lub cuab tam steel yog ib tug steel muaj heev hardenability thiab yuav tsum tau
    hardened los ntawm txias nyob rau hauv tseem huab cua. Cov kev siv ntawm ib lub ntsev da dej los yog tshuaj
    cua tshuab cua sov yog ntshaw kom txo decarburization, thiab yog hais tias tsis
    muaj, pob hardening nyob rau hauv siv suab coke yog pom tias. Lub
    kub ua hauj lwm yog feem ntau 1800 ° -1850 ° F, nyob ntawm seb loj seem.

    • quenching

    tua
    nyob rau hauv tseem huab cua los yog qhuav huab cua moj tej tawg. Yog hais tias nyuab ntawv yuav tsum tau hardened,
    ib tug interrupted roj quench yuav siv tau. Tua ib feem nyob rau hauv cov roj thiab tshem tawm
    los ntawm da dej thaum nws cia li poob nws cov xim (1000 ° -1100 ° F). Tag txias rau
    hauv qab no 150 ° -125 ° F nyob rau hauv huab cua, ces temper tam sim ntawd.

    • tempering
