1. Beams, txhua, kev txhawb nqa thiab lwm yam khoom siv thauj khoom hauv tsev tsim qauv.
2. Txhawb cov Cheebtsam hauv cov nqaj tseem ceeb xws li cov teeb tseem ceeb, cov teeb theem nrab, Piers, thiab lwm yam hauv Choj Cov Qauv.
3. Pab txhawb cov qauv hauv kev siv tshuab, cov chaw tsim khoom siv cov tub rog, petrochemicals thiab lwm thaj teb.

Cov pa roj carbon (c) cov ntsiab lus feem ntau yog hauv qab 0. 21%.
Silicon (Si) cov ntsiab lus feem ntau yog hauv qab 0. 40%.
Manganese (MN) cov ntsiab lus feem ntau yog qis dua 1.50%.
Phosphorus (p) thiab Sulphur cov ntsiab lus yog tshuaj tswj hauv qab 0. 035% feem.

Tos lub zog tsis pub tsawg tshaj 275MPA.
Lub zog tensile ranges los ntawm txog 490 txog 660 MPa.
Nws muaj cov ntshiab zoo, kev muaj zog thiab weldability.

Nws yog qhov tsim nyog rau cov txheej txheem qhov chaw nrog nruab nrab load yuav tsum tau ua, xws li muaj nroj tsuag muaj hnyav thiab lub hauv paus ntawm cov tuam tsev siab.

Cov pa roj carbon (c) cov ntsiab lus feem ntau yog hauv qab 0. 22%.
Cov silicon (Si) cov ntsiab lus feem ntau yog hauv qab 0. 55%.
Lub manganese (mn) cov ntsiab lus feem ntau yog qis dua 1.60%.
Cov phosphorus (p) thiab Sulphur (cov sulfur (s) tau tswj hwm hauv qab 0. 025%, feem.

Cov txiaj ntsig lub zog tsis pub tsawg tshaj 355 MPa.
Lub zog tensile nyob deb ntawm txog 590 mus rau 760 MPA.
Nws muaj lub zog siab thiab hardness, nrog rau kev muaj zog zoo thiab kev ua yeeb yam vuam.

Muaj feem xyuam rau cov txheej txheem sib xyaw nrog cov khoom lag luam siab yuav tsum tau, xws li cov choj loj, nkoj siab thiab cov tshuab hnyav.
