API 5L GR.X42 LSAW steel yeeb nkab yog dab tsi
API 5L X42 welded steel yeeb nkabnruj me ntsis raws li covAPI 5L tus qauvtsim los ntawm covLub koom haum American Petroleum (API),qha"X42"npe aYam tsawg kawg nkaus tawm lub zog ntawm 42,000 psi (kwv yees li 290 MPa). Qhov qib zog no ua rau nws tiv tausnruab nrab -kev sib kis ib puag ncigthaum tuav tau zoo heevweldability thiab formability.
Piv rau cov pa welded kav,API 5L X42nta iboptimized tshuaj muaj pes tsawg leeg tsim, nrog nwscarbon sib npaug (CE)khaws cia nyob rau hauv ib qho chaw tsim nyog. Qhov no ua kom ntseeg taukom muaj zog txausthaumtxo qhov kev pheej hmoo ntawm qhov txias txias thaum lub sij hawm vuam. Nws cov tshuaj muaj pes tsawg leeg muaj xws li:
- C <0.22%
- Mn Tsawg dua lossis sib npaug li 1.30%
- P Tsawg dua lossis sib npaug li 0.025%
- S Tsawg dua lossis sib npaug li 0.015%
- Trace alloying ntsiab xws liNb, V, Titxhawm rau txhim kho kev ua tau zoo tag nrho.
