Espesyal pou L80 13Cr anvlòp/OCTG anvlòp 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 /OCTG anvlòp/anvlòp ak Sur 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 Casing/OCTG Casing 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 /OCTG Casing/casing and tubing 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.
