ASTM A871 specification txhais tau hais tias muaj zog, qis-alloy steel phaj tsim los siv rau hauv cov qauv tubular thiab ncej, muab atmospheric corrosion kuj. Qib 60 thiab 65 muaj nyob rau hauv raws li dov, normalized, los yog quenched thiab tempered tej yam kev mob, raws li zoo raws li tej yam kev cai ntawm txhua yam khoom. Qhov tsawg kawg nkaus ASTM G101 Corrosion Resistance Index ntawm 6.0 raug yuam.
ASTM A 871-65 yog lub zog siab qis-alloy steel phaj nrog txhim kho atmospheric corrosion kuj. Qhov kev qhia tshwj xeeb no muab rau 65ksi yam tsawg kawg nkaus lub zog thiab 80ksi yam tsawg kawg nkaus tensile zog ntxiv rau atmospheric corrosion kuj ntawm cov hlau no nyob rau hauv feem ntau ib puag ncig zoo dua li cov carbon steels nrog los yog tsis muaj tooj liab ntxiv. Thaum tsim kom raug thiab raug rau huab cua, cov hlau no tuaj yeem siv liab qab (tsis pleev xim) rau ntau daim ntawv thov.
ASTM A871 Qib 60 yog lub zog muaj zog cov qauv hlau uas qhia tau hais tias kev txhim kho atmospheric corrosion kuj. Qhov no tsis tshua muaj hlau alloy ASTM A871 qib 60 steel phaj cov khoom tuaj yeem tsim kev tiv thaiv xeb zoo li txheej txheej ntawm qhov chaw thaum raug huab cua. Yog li, ASTM A871 qib 60 daim hlau tsis xav tau txheej txheej ntxiv.

ASTM A871 Hlau Phaj Txheej Txheem:
- Qhov zoo tshaj plaws structural steel rau tubular qauv thiab ncej.
- Muaj nyob rau hauv ob qib: 60 thiab 65.
- Muaj peev xwm ua tau rau peb hom tshuaj lom neeg: Hom I, Hom II thiab Hom IV.
- Tej zaum yuav muab raws li-dov, normalized los yog quenched thiab tempered.
- Nws muaj atmospheric corrosion kuj thiab yuav siv tau nyob rau hauv liab qab los yog unpainted tej yam kev mob.
- Thickness ntau dua 1 1/4" tej zaum yuav raug txiav txim tshwj xeeb, tab sis tsis tu ncua nyob rau hauv peb cov chaw faib khoom.
Sib piv ASTM A871 qib 60 thiab 65
- Qib 65 muaj zog me ntsis dua Qib 60, raws li yav tas los muaj minyield zog ntawm 450 Mpa thiab rau tom kawg, nws yog 415 MPa.
- Thaum lawv muaj tag nrho cov tshuaj zoo sib xws, qhov sib txawv me ntsis tuaj yeem muaj nyob nruab nrab ntawm ob qib kom ua tiav cov khoom siv kho tshuab uas xav tau.
- ASTM A871 HSLA steel qib 60 daim hlau muaj ntau dua li qib 65 daim hlau.
Txawm li cas los xij, lawv ob leeg muaj qhov zoo weldability thiab siv rau kev siv sab nraum zoov zoo sib xws
