- ASTM A516 Standard Specification rau Siab Vessel Phaj, Carbon Steel, rau Kev Pabcuam Nruab Nrab- thiab Kub Kub
ASTM A516 Qib 60 yog cov pa roj carbon steel phaj rau nruab nrab thiab qis kub siab cov hlab ntsha uas ua tau raws li ASTM specifications thiab yog siv rau ntau yam lag luam xws li roj thiab roj, petrochemicals, thiab hluav taws xob tsim. ASTM A516 Gr. 60 Pressure Vessel Steel Phaj yog qhov tsim nyog rau ntau yam kev siv vim nws qhov zoo weldability thiab qis-kub toughness.
ASTM A516 Gr. 60 steel phaj feem ntau muaj nyob rau hauv daim ntawv raws li dov. Normalized, stress-alleviated, los yog normalized thiab stress-alleviated daim hlau tuaj yeem yuav. Cov phaj hlau no ua tau raws li cov qauv txheej txheem ntawm NACE-MR0175 cov khoom siv roj av rau sulfide kev nyuaj siab tawg-resistant hlau cov ntaub ntawv thiab tau dhau HIC ntxiv rau SSC xeem. Txhawm rau kom ntseeg tau qhov tawv nqaij ntawm qhov kub thiab txias, ASTM A516 Gr.60 tau raug kuaj ntawm -46 degree ({11}} degree F). Charpy V-notch impact test feem ntau yog siv los ntsuam xyuas steel phaj cuam tshuam.

ASTM A516 Gr. 60 steel phaj muaj qhov zoo weldability, ua kom yooj yim rau kev tsim thiab vuam. Nws tuaj yeem txuas tau siv ntau yam txuj ci, xws li SMAW, GTAW, thiab GMAW.
Cov yam ntxwv ntawm ASTM A516 Gr.60
- Siab zog
- Zoo corrosion kuj
- Zoo weldability
- Zoo low-temperature toughness
ASTM A516 Gr.60 yog dav siv hauv roj av, tshuaj, chaw nres tsheb fais fab, boiler, thiab lwm yam lag luam los ua reactors, heat exchangers, separators, spherical tanks, airless tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied. Petroleum gas cylinders, high-pressure water pipes of hydropower stations, water turbine volutes, thiab lwm yam khoom siv thiab cov khoom siv.
ASTM A516 Gr.60 feem ntau yog muab rau hauv lub xeev, uas txhais tau hais tias nws tau ua kom sov siab tshaj nws qhov kev hloov pauv kub thiab txias hauv huab cua. Qhov kev kho cua sov no tsim cov microstructure nplua-grained thaum tseem ua kom tawv nqaij ntawm qhov kub thiab txias. Txhawm rau txhim kho cov khoom zoo, cov hlau tuaj yeem raug kho los ntawm quenching thiab tempering.
