AR500 yog qib ntawm hnav-resistant (AR) steel ntawv uas paub txog nws hardness, lub zog thiab hnav tsis kam. Qib no muaj ib qho ntawm cov qib hardness siab tshaj plaws ntawm cov qib AR steel ntawv qib - nrog rau Brinell Hardness Number (BHN) xws li 460-544 - thiab feem ntau yog siv rau hauv cov cheeb tsam uas muaj kev hnav siab thiab cuam tshuam. AR500 steel ntawv raws li ASTM E10 specifications rau Brinell hardness kuaj.

Qhov zoo ntawm AR500 steel:

Lub hardness thiab lub zog ntawm AR500 steel ntawv ua rau nws tsis tshua muaj resistant rau hnav thiab cuam tshuam. Cov khoom no ua rau AR500 steel yog cov khoom siv muaj zog thiab ruaj khov, uas yog qhov tseem ceeb hauv cov ntawv thov uas xav tau cov ntaub ntawv uas tuaj yeem tiv taus hnav hnyav.

AR500's durability kuj txhais tau hais tias cov khoom yuav tsum tau hloov tsawg dua li cov ntaub ntawv uas tsis muaj kev puas tsuaj, txo cov nqi ntawm cov khoom siv thiab tiv thaiv kev puas tsuaj ntawm cov khoom siv.

Qhov Loj:

Cov pa roj carbon ntau thiab cov tshuaj lom neeg ntxiv nrog rau hauv AR500 steel muab cov khoom muaj zog ntxiv thiab hnav tsis kam. Txawm li cas los xij, ntxiv cov pa roj carbon ntau kuj txo cov formability thiab lub zog ntawm AR500 piv rau lwm qib ntawm cov ntawv hlau. Lub hardness ntawm AR500 kuj txhais tau hais tias cov khoom yog ib qho nyuaj thiab yog li ntawd tsawg machineable dua me me thiab HSLA steels.

Txhawm rau txhim kho cov khoom tsim nyog hauv qhov chaw hnav khaub ncaws siab, AR500 steel tau txais kev kho cua sov hu ua quenching thiab tempering. Cov txheej txheem kev kho cua sov no hloov pauv cov qauv ntawm cov khoom siv hlau kom ua kom tawv nqaij thiab txo qhov iab.
