Espesyal pou L80 13Cr Sur/OCTG Sur se yon klas 80ksi martensitic en fe te dekri nan API 5CT ak ISO, 11960 (tubulars nan kabòn epi ba alyaj aciers). Alyaj a ki lajman itilize nan fòm tubulaires pou boîtier ak Sur/Sur lwil oliv ak gaz nan nivo ak anviwònman CO2. pH, chlorures, tanperati ak H2S ka limite sèvi nan lòt environnements. ISO 15156-3 limites dureté pou 22 Maks HRC pou sèvis Sure. Alyaj a prèske menm jan an pou 420 l' modifye.

Special for L80 13Cr Tubing/OCTG Tubing is a grade 80ksi martensitic stainless steel described in API 5CT and ISO 11960 (tubulars in carbon and low alloy steels). The alloy is widely used in tubular form for casing and tubing/tubing oil and gas in standard and CO2 environment. pH, chlorides, temperature and H2S can limit its use in other environments. ISO 15156-3 limits the hardness to 22 HRC max for sour service. The alloy is almost similar to AISI 420 modified.
