Ubwino wa AR Steel?
Jindalai Steel imapereka mbale zachitsulo za AR m'magulu akuluakulu ndi ang'onoang'ono kwa opanga ndi ogwira ntchito m'mafakitale omwe akufuna kukulitsa moyo wa ntchito ya zinthu zofunika kwambiri ndikuchepetsa kulemera kwa chipangizo chilichonse chomwe chimagwiritsidwa ntchito. Ubwino wogwiritsa ntchito mbale zachitsulo zosatha ntchito pokhudzana ndi kukhudzana ndi zinthu zokwawa ndi waukulu.
Mbale yachitsulo yosapsa ndi yolimba kwambiri komanso yosatha, imateteza bwino ku zotupa ndi mikwingwirima. Mtundu uwu wa chitsulo umagwira ntchito bwino pa ntchito zovuta, komanso umapereka kukana kugwedezeka. Mbale yachitsulo yosatha ndi kuvala pamapeto pake ingathandize kukulitsa moyo wa ntchito zanu ndikuchepetsa ndalama zomwe mumagwiritsa ntchito pakapita nthawi.

Katundu wa Mapepala a Chitsulo a AR400 NDI AR500
AR400 ndi "yolimba kwambiri", yosamva kuwawa, komanso yovala mbale ya alloy. Kulimba kwake ndi 360/440 BHN yokhala ndi kuuma pang'ono kwa 400 BHN. Kutentha kwa ntchito ndi 400°F. Chogulitsachi chapangidwa kuti chigwiritsidwe ntchito popangira zinthu zomwe zimafunika kulinganiza bwino kapangidwe kake, kusinthasintha, kulimba, ndi kukana kuwawa. Zitsulo zosamva kuwawa nthawi zambiri zimagulitsidwa ku mtundu wa kuuma osati mankhwala okhazikika. Pali kusiyana pang'ono kwa mankhwala kutengera mphero yopangira. Ntchito zake zitha kuphatikizapo kugwiritsidwa ntchito m'migodi, m'makola, pogwira zinthu zambiri, m'mafakitale achitsulo, ndi m'mafakitale a pulp & mapepala. Zinthu zovala mbale zimapangidwa kuti zigwiritsidwe ntchito m'liner; sizinapangidwe kuti zigwiritsidwe ntchito ngati zomangira zokha kapena zida zonyamulira.
AR500 ndi mbale yolimba, yosamva kukwawa, komanso yogwiritsidwa ntchito popanga zinthu zomangira. Kulimba kwake ndi 470/540 BHN yokhala ndi kuuma kwa 500 BHN. Chogulitsachi chapangidwa kuti chigwiritsidwe ntchito popanga zinthu zomwe zimafunika kuti pakhale kulimba, kulimba, komanso kukana kukwawa. Zitsulo zosagwirizana ndi kukwawa nthawi zambiri zimagulitsidwa ku mtundu wa kuuma osati mankhwala okhazikika. Pali kusiyana pang'ono kwa mankhwala kutengera mphero yopangira. Ntchito zake zingaphatikizepo kugwiritsa ntchito m'migodi, m'migodi, m'mafakitale opangira zinthu zambiri, m'mafakitale opangira zitsulo, komanso m'mafakitale opangira zinthu zamkati ndi mapepala. Zinthu zopangira mbale zomangira zimapangidwa kuti zigwiritsidwe ntchito ngati zinthu zodzichirikiza zokha kapena zonyamulira.
Mbale zachitsulo za AR400 VS AR450 VS AR500+
Mafakitale osiyanasiyana akhoza kukhala ndi "maphikidwe" osiyanasiyana a chitsulo cha AR, koma zinthu zopangidwa zimapangidwa ndi mayeso olimba - omwe amadziwika kuti Brinell Test - kuti adziwe gulu lomwe limagwera. Mayeso a Brinell omwe amachitidwa pa zipangizo zachitsulo za AR nthawi zambiri amakwaniritsa zofunikira za ASTM E10 poyesa kulimba kwa zinthu.
Kusiyana kwaukadaulo pakati pa AR400, AR450 ndi AR500 ndi Brinell Hardness Number (BHN), yomwe imasonyeza kuchuluka kwa kuuma kwa chinthucho.
AR400: 360-440 BHN Kawirikawiri
AR450: 430-480 BHN Kawirikawiri
AR500: 460-544 BHN Kawirikawiri
AR600: 570-625 BHN Kawirikawiri (yosazolowereka, koma imapezeka)
