Cov khoom siv kho tshuab ntawm SA516 Gr 70 yog raws li hauv qab no:

• Yield zog: 38 ksi (260 MPa) yam tsawg kawg nkaus

• Tensile zog: 70 - 90 ksi (485 - 620 MPa)

• Elongation: 23% yam tsawg kawg nkaus hauv 2 ntiv tes

SA516 Gr 70, ib qho kev lees paub dav dav ntawm cov hlau, pom kev siv dav hauv ntau qhov kev lag luam vim nws cov khoom zoo thiab cov yam ntxwv.

Hauv thaj tsam ntawm cov hlab ntsha siab, SA516 Gr 70 yog qhov nyiam heev. Nws muaj peev xwm tiv taus kev kub ntxhov thiab kub kub ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev tsim cov nkoj siv hauv kev lag luam chemical, petrochemical, thiab roj thiab roj. Cov hlab ntsha siab no ua lub luag haujlwm tseem ceeb hauv kev khaws cia thiab thauj cov khoom uas muaj kev phom sij txaus ntshai thiab ntseeg tau.

Kev tsim khoom lag luam kuj tau txais txiaj ntsig los ntawm kev siv SA516 Gr 70. Nws yog feem ntau ua haujlwm hauv kev tsim cov tshuab hnyav thiab cov khoom siv uas muaj zog thiab kav ntev yog qhov tseem ceeb. Piv txwv li, qhov chaw ntawm cov cranes loj, cov khoom siv mining, thiab cov tshuab tsim kho feem ntau yog tsim los ntawm qib steel no kom ntseeg tau tias lawv tuaj yeem tiv taus cov khoom hnyav thiab ua haujlwm hnyav.

Hauv kev lag luam hluav taws xob, tshwj xeeb tshaj yog hauv cov chaw tsim hluav taws xob, SA516 Gr 70 yog siv los tsim cov khoom siv boiler. Cov hlau tsis kam mus rau qhov kub thiab txias thiab kev hloov pauv siab ua rau nws tsim nyog rau kev tiv thaiv cov kev xav tau ntawm kev ua haujlwm hauv boilers, ua rau muaj txiaj ntsig zoo thiab muaj kev nyab xeeb ntawm lub zog.

Kev tsim cov tank cia yog lwm qhov chaw uas SA516 Gr 70 ci. Txawm hais tias khaws cia cov kua los yog cov pa roj, cov hlau tsis muaj zog corrosion thiab cov khoom siv dag zog ua kom lub neej ntev thiab kev ncaj ncees ntawm cov tso tsheb hlau luam, txo qhov kev pheej hmoo ntawm kev xau thiab xyuas kom muaj cov khoom khaws cia.

Kev tsim kho kev lag luam kuj ua rau kev siv tseem ceeb ntawm SA516 Gr 70. Nws tuaj yeem pom nyob rau hauv cov txheej txheem ntawm cov qauv loj, xws li cov txuas hniav thiab cov tsev, qhov twg nws lub zog muab kev ruaj ntseg thiab kev nyab xeeb.

Tsis tas li ntawd, hauv kev lag luam marine, qib steel no yog siv rau hauv kev tsim cov nkoj thiab offshore platforms. Nws lub peev xwm los tiv thaiv corrosive los ntawm cov dej ntsev thiab qhov hnyav marine ib puag ncig ua rau nws muaj kev ntseeg siab rau cov ntawv thov no.

Hauv kev xaus, ntau yam thiab kev ntseeg siab ntawm SA516 Gr 70 ua rau nws yog ib qho khoom siv tsis tau hauv ntau qhov kev lag luam. Nws cov khoom sib xyaw ua ke tshwj xeeb ua rau nws ua tau raws li qhov xav tau ntawm ntau yam kev siv, ua rau muaj kev nyab xeeb, ua haujlwm tau zoo, thiab lub neej ntev ntawm cov khoom siv thiab cov qauv uas nws ua haujlwm.
