Corrosion Resistance:

Alloying cov ntsiab lus xws li chromium thiab npib tsib xee muab kev tiv thaiv corrosion, ua rau ASTM tsawg alloy steel daim hlau haum rau siv nyob rau hauv corrosive ib puag ncig.

Hnav Resistance:

Qee yam ASTM cov hlau tsis tshua muaj hlau yog tsim los tiv thaiv kev puas tsuaj thiab hnav, ua rau lawv zoo tagnrho rau kev siv hauv cov ntawv thov uas muaj kev sib txhuam thiab hnav.

Yooj yim ntawm vuam:

ASTM qis alloy steel phaj feem ntau muaj qhov zoo weldability, uas yooj yim rau kev tsim thiab kev tsim kho. Qhov no yog qhov tseem ceeb tshwj xeeb rau kev siv cov txheej txheem uas feem ntau siv vuam.

Tus nqi -zoo:

Economic Advantage: Muab piv rau cov hlau alloy siab, ASTM cov hlau tsis tshua muaj hlau phaj yog tus nqi ntau dua -zoo vim lawv cov ntsiab lus qis alloying thaum tseem muab cov khoom zoo tshaj cov pa roj carbon steel.
