ASTM A516 Gr 65, teev nyob rau hauv Astm A516 / A516M Txuj Ci, yog cov pa roj carbon steel tau tsim rau Welded Siab Missch trougness. Nrog tsawg kawg vim muaj zog ntawm 240 MPa, nws muaj kev sib npaug ntawm lub zog thiab ductility, ua rau nws zoo tagnrho rau kev tso ntaub ntawv thiab kev hloov pauv kub. Lub ASTM A516 Gr65 feem ntau tau txhim kho nrog hydrogen ua rau kev tawg pleb (HIC) thiab NACE MR0175 ua raws li kev ntseeg tau zoo li sour roj pipelines.
