St50-2 Khoom HSLA Phaj

Cov Lus Qhia Yooj Yim

Ntaus: Siab {- muaj zog tsawg -} alloy (hsla) Hlau phaj

Lub hom phiaj: Raws li German Din cov qauv (piv txwv li, DIN 17100, tsis muaj lawm tab sis tseem hais txog), St50-2 yog ib feem ntawm "ST" rau cov qauv hlau qauv.Kev Tsim Kev Tsim Kev Puas Tsuaj:

Tus st: Abbreviat rau"Stahl"(German rau "Hlau").

50: Qhia txog ib qho kev kawm qib siab tshaj plaws ntawm nominal

2: Feem ntau txhais tau tias yog qhov ua tau zoo lossis ua haujlwm (piv txwv li, cov dab tsi lossis thermomecharanically dov rau kev txhim kho cov khoom siv).

Cov Khoom Siv Tseem Ceeb

Cov Khoom Siv Neeg Kho Tshuab

Lub zog tensile: ~ 500-630 MPa (nyob ntawm cov tuab thiab tsim kev tsim khoom).

Paib lub zog: Loj dua los yog sib npaug rau 345 MPa (rau cov ntu thinner; txo qis nrog cov tuab ntxiv).

Elongation: Loj dua los yog sib npaug rau 18-22% (kev du ncauj zoo rau cov qauv tsim).

Kev Cuam Tshuam: Muaj kev nyuaj ntawm cov huab cua kub (tuaj yeem kuaj xyuas cov ntawv thov tshwj xeeb).

Qhov zoo heev

Lub zog siab - rau - qhov hnyav} qhov hnyav. Piv: Txo cov khoom tuab thiab qhov hnyav hauv cov qauv tsis muaj kev cuam tshuam load {{bearing} cov kabmob muaj peev xwm.

Zoo Weldability: Cov ntsiab lus muaj cov pa roj carbon tsawg thiab sib npaug ntxiv cov kev pheej hmoo ntawm kev pheej hmoo ntawm tshav kub {}} bead cuam tshuam thaj chaw (Haz) brittleness.

Muaj meej: Haum rau dabtsi yog khoov, stamping, thiab lwm yam txias - Ua cov txheej txheem vim yog kev ua tau zoo.

Corrosion Kuj: Zoo dua atmospheric corrosidion tsis kam dua li cov roj carbon hlau, ua tsaug rau cov ntsiab lus xws li CU (hauv qee qib).

Alloy muaj pes tsawg leeg (raug)

Tsawg Alloy Ntsiab Lus(tag nrho tsawg dua lossis sib npaug rau 3%):

Carbon (c): ~ 0.15-0.25% (khaws cov roj carbon ntau rau weldability).

Manganese (mn): ~ 1.0-1.6% (txhim kho kom tau lub zog thiab ua tsis taus).

Silicon (si): ~ 0.15-0.50% (Txhim kho Deoxidation thiab lub zog).

Microalloying ntsiab(Xaiv tau) :: yuav suav nrog cov nyiaj tsawg ntawm V, NB, lossis Ti rau cov khoom siv qoob loo thiab lub zog ua kom zoo.
