Cov yam ntxwv tseem ceeb thiab qhov zoo
- Pre-Hardened Condition:Feem ntau P20 thiab 718 qib tau muab ntawm28-36 HRC. Tnws tso cai rau cov neeg tsim pwm los tshuab cov hlau ncaj qha mus rau qhov kawg zoo yam tsis muaj kev pheej hmoo ntawm kev cuam tshuam los ntawm kev kho cua sov tom ntej.
- Zoo Polishability:High purity (ESR yeem) tso cai rau cov hlau kom ua tiav qhov siab -gloss lossis daim iav tiav, qhov tseem ceeb rau cov khoom yas (lens, fwj).
- Corrosion Resistance:Stainless qib zoo li1.2083 (S136)tiv thaiv corrosion los ntawm acidic plastics (xws li PVC) thiab cov chaw ua haujlwm ntub dej, txo cov pwm txij nkawm.
- Uniform Hardness:Qib nrog Nickel (xws li 1.2738) kom ntseeg tau tias qhov nyuaj ntawm qhov chaw mus rau qhov tseem ceeb, txawm tias nyob hauv cov blocks txog li 400 mm tuab.
- Yees duab-etching Muaj peev xwm:Uniform microstructure kom clear, zoo ib yam texturing qauv.
Tej kev siv
Yas Mould Steel yog ntau yam, txhawb kev lag luam los ntawm cov khoom siv rau tsheb:
Automotive interiors & Exteriors
Cov pwm loj rau cov pob, dashboards, thiab qhov rooj vaj huam sib luag (feem ntau yog siv1.2738 / 718H).
Cov Khoom Siv Hauv Tsev

FAQ
Q1: Qhov txawv ntawm P20 thiab 718 Hlau yog dab tsi?
A1: P20 (1.2311) yog tus qauv yas pwm steel . 718 (1.2738) yog ib qho kev hloov kho tshiab uas muaj ~ 1% Nickel. Qhov no Nickel ntxiv txhim kho qhov "hardenability," kom ntseeg tau tias cov blocks loj muaj qhov sib txawv ntawm qhov tseem ceeb . 718 kuj muaj qhov zoo dua polishability me ntsis.
Q2: "Pre-hardened" txhais li cas?
A2: Nws txhais tau hais tias cov hlau tau muab cov cua sov uas twb muaj lawm - kho kom ua haujlwm nyuaj (feem ntau yog 28-36 HRC). Qhov txiaj ntsig yog tias tus neeg siv khoom tuaj yeem siv lub tshuab pwm thiab siv tam sim ntawd yam tsis tau xa tawm mus rau kev kho cua sov, txuag lub sij hawm thiab tshem tawm qhov kev pheej hmoo ntawm warping.
Q3: Thaum twg kuv yuav tsum siv S136 (Stainless Pwm Hlau)?
A3: Koj yuav tsum siv S136 lossis 1.2083 thaum:
Moulding corrosive plastics (xws li PVC lossis Acetates) uas tso cov kua qaub.
Cov pwm ua haujlwm hauv qhov chaw ntub dej.
Yuav tsum muaj - qib kho qhov muag daim iav tiav (piv txwv li, rau tsom iav lossis lub raj mis ntshiab).
Q4: Koj puas tuaj yeem muab ESR zoo rau cov pwm yas?
A4: Yog. Rau cov ntawv thov uas xav tau Super Mirror Finish (xws li, optical lo ntsiab muag), peb pom zoo ESR (Electroslag Remelting) qib S136 lossis 718, vim nws tshem tawm impurities uas tuaj yeem ua rau pitting thaum polishing.
