XAR400 yog ib qho tshwj xeeb cov qauv hlau uas muaj kev hnav tsis kam, feem ntau qhov siab dua qhov tawv, siab dua hnav tsis kam. Qhov hnav no-resistant tshwj xeeb cov qauv hlau muaj qhov nruab nrab hardness ntawm 400 HB thiab yog quenched, los yog hardened thiab quenched, muab nws ib tug zoo martensitic -bainitic microstructure. Qhov sib ntxiv ntawm molybdenum, npib tsib xee thiab boron alloys ua kom muaj kev ntxhib los mos thoob plaws hauv cov kev taw qhia tuab.
Siv rau hauv hnav-cov qauv raug pom, xws li cov ntaub thaiv npog rau cov neeg muag khoom thiab cov bulldozers, plhaub phab ntsa. Kev them nyiaj yug lossis kev txhawb nqa daim hlau; txiav daim hlau rau tsheb lub cev yob. Hnav- daim hlau tiv taus; sib tov thiab conveying ntsiab, inclined grooves, qhia, tshuab cuab yeej, crushers thiab shredders, khib briquetting presses, shovels, paving abrasives thiab ua liaj ua teb machinery.

Cov ncauj lus kom ntxaws txog kev hnav resistant hlau
Lub ntsiab zoo ntawm steel hnav phaj cov khoom yog nws hardness. Peb muag cov ntawv hnav raws li lawv qhov nyuaj raws li ntsuas los ntawm Brinell Hardness Test - feem ntau 400HB thiab 500HB qib. Yog tias koj qhov kev qhia tshwj xeeb tau ntsib Rockwell kuaj, peb tuaj yeem muab qhov ntawd thiab.
Cov hlau uas muaj qhov ntsuas HB siab (Brinnell hardness) yog qhov tsim nyog rau cov ntawv thov uas hnav tsis kam yog qhov tseem ceeb. Qhov txiaj ntsig ntawm kev siv coj-cov hlau tsis muaj zog yog tias nws tuaj yeem txuas ntxiv lub neej ntawm koj cov nroj tsuag, tshuab lossis lub tsev. Qhov no tuaj yeem txhim kho kev ntseeg siab, ua haujlwm ntev thiab kev nyab xeeb ntawm cov qauv thiab cov khoom siv. Nws kuj tseem pab txo cov nqi kho mob cuam tshuam nrog cov khoom siv hnav thiab tsis ua haujlwm.
400 HB steel yog ntau dua 3 npaug ntawm cov hlau me me (120HB) tab sis tsuas yog ib qho - thib peb nyuaj li steel hlau (1250HB). Piv txwv siv xws li kev tsim kho tshuab, hlais, bulldozers thiab excavators, thoob thiab conveyors. Hlau yog quenched kom nws hnav-resistant; nws kuj tuaj yeem raug tempered kom nws hardness. Lower HB feem ntau muab cov khoom txias txias zoo thiab zoo weldability. Weldability feem ntau tsis txo qis nrog nce hardness.
