Cov Ntawv Thov

S355jR Z25 yog qhov zoo tagnrho rauWelded cov qauv txheej txheem yuav tsum muaj cov thickness-kev ncaj ncees, xws li:

(1) kev siv ua haujlwm hnyav

Tus choj: Tuab ob phaj phaj, thawv ntu, thiab piers.

High-aw Vaj Tsev: Kab ntawv, hloov daim hlau, thiab seismic-resistant pob qij txha.

Tus yam ntxwv: A {{30- Zaj Dab Neeg Steel thav duab hauv av qeeg siv S355jR Z25 rau qhov tseem ceeb welded sib txuas.

(2) Kev Siv Neeg Kho Tshuab Engineering

** Cranes thiab hnyav Machinery **: Cov phiaj hlau, welded thav ntawv, thiab load-bear-bear-bearing nkhaus.

Tus yam ntxwv: A {500- nyhav ib tak crawler crane lub thawv boom sib koom siv z25 daim hlau kom whotand cyclic chaw thau khoom.

(3) Offshore thiab marine lug

Offshore platforms: Jacka tsho qauv, hull cov khoom, thiab cov noded.

Tus yam ntxwv: Lub hiav txwv North Rig siv S355jR Z25 rau tuab-walled welded chambers.

(4) Cov Khoom Siv Muaj

Siab: Daim Hlau rau Tsawg-rau-Nruab Nrab Lub Siab Tso Tsheb Hlau (nrog Ntawv Pov Thawj Kom Zoo).

Hlau Castings: Cov phiaj hlau rau cov tshuab muaj cov tshuab loj.

Lub ntsiab	Cov ntsiab lus (%)	Lub luag hauj lwm
C	Tsawg dua los yog sib npaug rau 0. 22	Sib npaug lub zog thiab weldability (cov pa roj carbon tsawg).
Si	Tsawg dua los yog sib npaug rau 0. 55	Txhim kho rau oxidation thiab txhim kho deoxidation.
Mn	Tsawg dua los yog sib npaug rau 1.60	Nce lub zog ntawm cov tawv tawv tawv.
P/S	Tsawg dua li lossis sib npaug rau 0. 035	Txo qhov brittleness. Tswj nruj rau kev cuam tshuam thiab vuam ua tau zoo.
Nb \/ v \/ ti	Yeem (Microalloying)	Refines cov qauv lis rau kev txhim kho kev txhim kho nruj (tsis yog ib txwm muaj nyob hauv JR qib).
