ASTM A131 EH32 CARBUDER HLAU Phaj

Nyob rau hauv cov nqe lus ntawm cov tshuaj muaj tshuaj, A131 Eh32 thiab E32 cov roj hmab muaj feem ntau sib xyaw ntawm cov hlau, carbon, siosphorus, sulfur, thiab kab ntawm lwm cov khoom siv alloy. Qhov sib npaug ntawm cov ntsiab lus ua kom muaj zog tensile muaj zog thiab tawv, tseem ceeb heev rau kev nyuaj siab thiab kev ntxhov siab ib puag ncig ntsib hauv cov av marine.

Mechanically, cov phiaj hlau no nthuav qhia lub zog zoo thiab ductility. Lawv muaj cov txiaj ntsig siab thiab lub zog tensile, tso cai rau lawv tau nqus cov khoom hnyav tsis muaj kev sib deev tsis muaj kev ntseeg siab. Tsis tas li ntawd, lawv txoj kev txhim kho kom zoo kom lawv tau nqus thiab faib cov kev cuam tshuam zoo, txo qis kev pheej hmoo ntawm cov kab nrib pleb lossis kev pheej hmoo.

Lub xeev kho cua sov ntawm A131 EH32 / E32 cov phiaj hlau yog ua tib zoo tswj lawv cov khoom siv. Feem ntau, cov phiaj xwm yauv ua ib txwm ua lossis quenching thiab tempering cov txheej txheem, uas txhim kho lawv cov kev nruj thiab tsis kam mus rau brittle baciture. Qhov kev pab kub no tseem pab kho cov qauv sib dhos ntawm cov hlau, txhim kho nws cov kev ua tau zoo tag nrho.
