I-API 5L X42 Ukwakhiwa kweMichiza
Ukuqulunqwa kweMichiza ye-PSL 1 Ipayipi ene-t ≤ 25.0 mm (0.984 in.)
Ukuqulunqwa kweMichiza ye-PSL 2 Ipayipi ene-t ≤ 25.0 mm (0.984 in.)
Kwiimveliso zemibhobho yentsimbi ye-PSL2 ehlalutywe ngeumxholo wekhabhoni ≤0.12%, icarbon elingana CEpcmingabalwa kusetyenziswa le fomula ilandelayo:
CEpcm= C + Si/30 + Mn/20 + Cu/20 + Ni/60 + Cr/20 + Mo/15 + V/15 + 5B
Kwiimveliso zemibhobho yentsimbi ye-PSL2 ehlalutywe ngeumxholo wekhabhoni > 0.12%, icarbon elingana CEllwingabalwa kusetyenziswa le fomula ingezantsi:
CEllw= C + Mn/6 + (Cr + Mo + V)/5 + (Ni +Cu)/15
Ukuma kweMichiza ene-t ＞ 25.0 mm (0.984 ngaphakathi.)
Oku kunokuxoxwa ngokubhekisele kumxube wekhemikhali ongentla.
