Choj Tsev Hlau Daim Hlau

Hauv kev tsim choj, choj hlau daim hlau ua haujlwm raws li cov pob txha ntawm lawv cov qauv kev ncaj ncees. Lawv tuaj yeem tiv taus qhov hnyav hnyav, thiab huab cua huab cua, thiab ua kom muaj kev nyab xeeb ntawm cov choj. Choj steel phaj muab lub zog, toughness, thiab versatility tsim nyog los txhawb kev thauj mus los tseem ceeb infrastructure.

● Lub zog muaj zog: Choj steel daim hlau muaj lub peev xwm thauj khoom muaj zog thiab tsim nyog rau cov qauv hlau loj loj.

● High ductility: Choj steel daim hlau muaj lub zog tensile siab thiab tuaj yeem tiv taus lub zog tensile loj yam tsis tau tawg yooj yim.

● Weld-muaj peev xwm: Choj steel daim hlau muaj qhov tsis tshua muaj kev cuam tshuam rau vuam tawg thiab yooj yim rau vuam, uas pab tau ntau yam hauv kev tsim cov choj hlau.

● Corrosion tsis kam: Choj steel phaj muaj kev tiv thaiv corrosion zoo thiab tuaj yeem yooj yim tiv nrog marine ib puag ncig.

ASTM A709 steel daim hlau yog tsim rau ntau yam txuas txuas, xws li girders, trusses, thiab lwm yam khoom siv. Muaj ntau qib sib txawv ntawm ASTM A709 steel daim hlau rau siv.

Qib 50: ASTM A709 Gr.50 steel daim hlau muaj qhov tsawg kawg nkaus yield zog ntawm 50 ksi (345 MPa), thiab lawv siv nyob rau hauv txuas hniav nrog txhim kho atmospheric corrosion kuj.

Qib 50W: Gr.50W muaj qhov zoo ntawm atmospheric corrosion tsis kam tshaj Gr.50.

Qib HPS 50W: A709 HPS 50W steel daim hlau yog tus cwj pwm los ntawm kev txhim kho toughness thiab weldability. Lawv feem ntau siv nyob rau hauv cov choj nrog cov kev xav tau siab thiab cov kev xav tau.

Qib HPS 70W: Qib steel phaj no muaj qhov tsawg kawg nkaus lub zog ntawm 485 MPa (70 ksi) thiab cov yam ntxwv zoo tshaj plaws ntawm huab cua. Lawv tsim nyog rau kev thov choj thov.

Peb tau txais lub koob npe nrov rau cov ntawv hlau zoo thiab cov neeg siv khoom txaus siab. Tsis muaj teeb meem npaum li cas ntawm koj cov phiaj xwm choj, peb pab neeg ua haujlwm tuaj yeem coj koj cov kev daws teeb meem zoo tshaj plaws.
