ABS FH32, qib siab -kev ua tau zoo steel qib, tshwj xeeb yog tsim los siv rau hauv qhov tsis tshua muaj siab - qhov kub thiab txias, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv hauv hiav txwv. Cov hlau tshwj xeeb no, suav nrog nws cov tshuaj muaj pes tsawg leeg, kev coj tus cwj pwm, thiab kev siv, yog qhov tseem ceeb rau kev nkag siab nws tus nqi hauv ultra- qhov kub thiab txias.

ABS FH32 yog ib qho kev xaiv tshwj xeeb rau kev siv hauv ultra- cov ntawv thov dej hiav txwv qis. Nws cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab muab tshwj xeeb lub zog, ductility, corrosion kuj, thiab qaug zog tsis kam. Nws txoj kev siv dav hauv kev tsim cov nkoj thiab cov qauv tawm sab nrauv pom tau tias nws hloov tau mus rau ntau yam kev siv dej hiav txwv, ua rau nws muaj kev ntseeg siab rau cov neeg tsim qauv thiab cov kws tsim qauv ua haujlwm hauv qhov chaw huab cua.
