Cov txiaj ntsig ntawm AR Steel?
Jindalai Steel muab AR steel phaj loj thiab me me rau cov neeg tsim qauv thiab cov neeg ua haujlwm cog nrhiav kom ntev kev pab cuam lub neej ntawm cov khoom tseem ceeb thiab txo qhov hnyav ntawm txhua chav tsev muab tso rau hauv kev pabcuam. Cov txiaj ntsig ntawm kev ua haujlwm hnav-resistant steel phaj hauv daim ntawv thov cuam tshuam thiab / lossis zawv zawg sib cuag nrog cov khoom siv abrasive yog qhov loj heev.
Abrasion resistant steel phaj yog heev ruaj thiab hnav-resistant, tiv thaiv zoo tiv thaiv scuffs thiab khawb. Hom hlau no ua haujlwm zoo hauv kev siv hnyav, thiab tseem muaj qee qhov cuam tshuam. Hnav resistant steel phaj thaum kawg yuav pab kom ntev lub neej ntawm koj daim ntawv thov thiab txo koj cov nqi nyob rau hauv lub sij hawm ntev.

Cov khoom ntawm AR400 THIAB AR500 Steel Phaj
AR400 yog "thru-hardened", abrasion resistant, alloy hnav phaj. Hardness ntau yog 360/440 BHN nrog lub nominal hardness ntawm 400 BHN. Kev pabcuam kub yog 400 ° F. Cov khoom lag luam phaj no yog tsim los siv rau hauv cov ntawv thov uas yuav tsum muaj qhov sib npaug ntawm formability, weldability, toughness thiab abrasion tsis kam. Abrasion resistant steels feem ntau yog muag rau hardness ntau yam thiab tsis yog ib qho chemistry ruaj. Cov kev hloov pauv me me hauv chemistry yog tam sim no nyob ntawm lub tshuab ua khoom. Cov ntawv thov tuaj yeem suav nrog kev siv hauv mining, quarries, bulk khoom tuav, steel mills, thiab pulp & ntawv industries. Hnav phaj cov khoom yog tsim los rau daim ntaub ntawv liner; lawv tsis yog siv los ua cov qauv txhawb nqa tus kheej lossis nqa cov khoom siv.
AR500 yog "thru-hardened", abrasion resistant, alloy hnav phaj. Hardness ntau yog 470/540 BHN nrog lub nominal hardness ntawm 500 BHN. Cov khoom siv phaj no yog tsim los siv rau hauv cov ntawv thov uas yuav tsum muaj qhov sib npaug zoo ntawm kev cuam tshuam, toughness thiab abrasion tsis kam. Abrasion resistant steels feem ntau yog muag rau hardness ntau yam thiab tsis yog ib qho chemistry ruaj. Kev hloov pauv me ntsis hauv chemistry yog tam sim no nyob ntawm lub tshuab ua khoom. Cov ntawv thov tuaj yeem suav nrog kev siv hauv mining, quarries, bulk khoom tuav, steel mills, thiab pulp & ntawv industries. Hnav phaj cov khoom yog tsim los rau daim ntaub ntawv liner; lawv tsis yog siv los ua cov qauv txhawb nqa tus kheej lossis nqa cov khoom siv.
AR400 VS AR450 VS AR500+ Steel Phaj
Cov mills sib txawv tuaj yeem muaj cov "daim ntawv qhia" sib txawv rau AR steel, tab sis cov khoom tsim tau raug tswj xyuas qhov nyuaj - hu ua Brinell Test - txhawm rau txiav txim siab qeb uas nws ntog. Brinell kev sim ua ntawm AR steel cov ntaub ntawv feem ntau ua tau raws li ASTM E10 cov lus qhia tshwj xeeb rau kev ntsuas cov khoom tawv.
Qhov kev sib txawv ntawm AR400, AR450 thiab AR500 yog Brinell Hardness Number (BHN), uas qhia txog cov khoom qib hardness.
AR400: 360-440 BHN Feem ntau
AR450: 430-480 BHN Feem ntau
AR500: 460-544 BHN Feem ntau
AR600: 570-625 BHN Feem ntau (tsawg dua, tab sis muaj)
