API 5L X42 pipeline steel phaj thiab coil yog siab -lub zog qis-alloy (HSLA) cov ntaub ntawv tsim los rau qis- mus rau - nruab nrab siab siab roj thiab roj xa mus kav. Ntawm no yog cov ncauj lus kom ntxaws tsom xam rau ob daim ntawv thov phaj thiab coil, suav nrog cov qauv kev lag luam tshiab thiab kev nce qib:

1. Kev qhia tshwj xeeb

Qib Qib:

X42sib raug rauL290nyob rau hauv GB / T 9711, nrog "X" denoting pipeline steel thiab "42" qhia qhov tsawg kawg nkaus tawm lub zog ntawm42 ksi (290 MPa) .

API 5L PSL2muaj kev tswj xyuas nruj dua cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab rau cov ntawv thov tseem ceeb, thaum PSL1 yog qhov tsim nyog rau kev siv dav dav.

Tshuaj muaj pes tsawg leeg:

Cov pa roj carbon tsawg (tsawg dua lossis sib npaug li 0.20%): Ua kom cov weldability zoo heev thiab txo qhov kev pheej hmoo ntawm pob txha tawg.

Manganese (1.20-1.60%): Txhim khu lub zog thiab toughness.

Microalloying Elements:

Nb (0.01–0.05%), V (0.01–0.07%), thiabTi (0.01–0.04%)refine grain qauv kom txhim kho lub zog thiab ductility.

Sulfur Control (tsawg dua lossis sib npaug rau 0.030% PSL1, Tsawg dua lossis sib npaug rau 0.003% PSL2): Txo cov sulfide inclusions los tiv thaiv hydrogen -induced cracking (HIC) nyob rau hauv qaub ib puag ncig .

Mechanical Properties:

Yield zog: 290–415 MPa (PSL2), zoo tagnrho rau qis -siab tshuab.

Tensile zog: 415-620 MPa, ua kom muaj kev ncaj ncees.

Elongation: Ntau dua lossis sib npaug li 22%, muab cov ductility zoo dua rau kev ua kom txias ({1}}cov ntawv thov (xws li coil dabtsi yog khoov).

Impact Zog: Ntau dua lossis sib npaug rau 34 J ntawm -20℃(PSL2), ua tau raws li qhov xav tau ntawm huab cua txias.

2. Kev kho cua sov thiab ntau yam

X42N: Normalized los optimize grain qauv, haum rau dav - lub hom phiaj pipelines.

X42M: Thermomechanical dov (TMCP) rau kev sib npaug zog thiab weldability, dav siv nyob rau hauv onshore tej yaam num.

X42 NS: Normalized nrogNACE MR0175 ua rawsrau kev pabcuam qaub (H₂S/CO₂ ib puag ncig), kev kuaj 96-teev HIC (NACE TM0284) thiab 720-teev SSC kuaj (NACE TM0177).
