SUS410L Stainless Hlau: Tsawg-Carbon Martensitic Qib rau siab-Toughness Applications

SUS410L yog qhov qis- carbon martensitic stainless hlau (C Tsawg dua lossis sib npaug rau 0.03, Cr=11.5%-13.5%) nrog zoo weldability thiab toughness. Piv nrog rau tus qauv SUS410, nws cov ntsiab lus qis qis txo qhov kev pheej hmoo ntawm kev sib tsoo txias tom qab vuam, thiab nws tuaj yeem tau txais lub zog sib npaug thiab tawv los ntawm kev kho cua sov.

Core Parameters

Chemical Composition (wt%): C Tsawg dua lossis sib npaug rau 0.03, Si Less dua lossis sib npaug rau 1.00, Mn Tsawg dua lossis sib npaug rau 1.00, P Tsawg dua lossis sib npaug rau 0.040, S Less dua lossis sib npaug rau 0.030, Cr=11.50-13.50, Fe=Sib npaug

Mechanical Properties (Quenched & Tempered): Tensile Strength Ntau dua los yog sib npaug rau 550MPa, Lub zog muaj zog ntau dua lossis sib npaug rau 380MPa, Elongation Ntau dua lossis sib npaug li 20%, Hardness 25-30HRC

Kev Pabcuam Kub: -40℃txog 400℃(kev pabcuam txuas ntxiv)

Qib sib npaug: EN 1.4003, UNS S41003, GB 022Cr12

Kev Ua Haujlwm Zoo: Cov ntsiab lus qis carbon ua kom zoo weldability yam tsis muaj preheating lossis post-weld heat treatment; zoo toughness ntawm qis kub (tshuaj toughness Ntau tshaj los yog sib npaug rau 40J ntawm -40 degree); nruab nrab corrosion kuj nyob rau hauv atmospheric ib puag ncig; sib nqus, haum rau kev siv cov khoom sib nqus.

Tej kev siv: Tsawg- lub siab lub cev lub cev, lub twj tso kua mis, cov khoom siv hydraulic, cov khoom noj khoom haus, cov khoom siv phais mob, cov hlau nplaum sib nqus, cov khoom siv hauv tsheb.

Tswv yim Q&A

Q1: Qhov txawv ntawm SUS410L thiab SUS410 yog dab tsi? A1: Cov ntsiab lus sib txawv yog cov ntsiab lus carbon: SUS410L (C Tsawg dua lossis sib npaug li 0.03%) vs. SUS410 (C=0.15%-0.25%). SUS410L muaj qhov zoo dua weldability thiab toughness, thaum SUS410 tuaj yeem tau txais cov tawv tawv dua (txog 45HRC) tom qab kev kho cua sov, nrog kev hnav zoo dua.

Q2: Puas tuaj yeem siv SUS410L hauv qhov chaw qis - qhov kub thiab txias? A2: Yog. Nws tuaj yeem siv tau ruaj khov ntawm -40 degree, nrog kev cuam tshuam toughness Ntau dua lossis sib npaug ntawm 40J, uas yog siab dua SUS410 (qhov cuam tshuam qhov hnyav tsawg dua lossis sib npaug rau 20J ntawm -40℃). Nws yog qhov tsim nyog rau cov khoom siv hluav taws xob qis hauv cov cheeb tsam txias.

Q3: Cov txheej txheem kev kho cua sov dab tsi tsim nyog rau SUS410L? A3: Rau siab toughness: annealing ntawm 780-830 degree, cua txias, hardness tsawg dua los yog sib npaug rau 180HB; rau qhov sib npaug ntawm lub zog thiab lub zog: quenching ntawm 950-1000 degree, roj txias + tempering ntawm 200-300 degree, hardness 25-30HRC.

Q4: Puas yog SUS410L haum rau daim ntawv thov zaub mov? A4: Yog. Nws ua tau raws li cov qauv kev nyab xeeb khoom noj (xws li FDA 21 CFR 175.300) tom qab kev kho mob passivation. Nws yog qhov tsim nyog rau cov khoom noj khoom haus xws li cov hniav sib xyaw thiab cov tso tsheb hlau luam uas tsis tiv tauj cov khoom noj acidic rau lub sijhawm ntev.

Q5: Yuav ua li cas txhawm rau txhim kho corrosion ntawm SUS410L? A5: Ua kev kho mob passivation nrog 20% ​​nitric acid tov (chaw kub, 30 feeb) tom qab ua tiav los ua cov ntaub ntawv tuab chromium oxide; siv cov tshuaj tiv thaiv- xeb roj lossis pleev xim rau qhov chaw tiv thaiv hauv qhov chaw ntub dej; zam kev sib cuag nrog chloride ion- muaj cov xov xwm.
