ASME SA285 Qib B (SA285GR.B) Cov Khoom Siv Hluav Taws Xob uas muaj kev ntxhov siab rau Astm Heev Tsis Zoo Li Cas Rau Kev Nyuaj Siab {} b, hais txog weldability tsis muaj Alloys, ua rau nws effusformical rau tsis - cov kev pabcuam corrosive. Piv rau Astm 285 qib A, nws muab lub zog siab dua rau cov khoom siv nias ib txwm ua rau feem ntau yog en p265ghghghghghghghght rau qis qis {13} siab} siab siv.

Cov Ntawv Thov thiab Qhov Zoo Hauv Siab Nkoj Tshuab
Sa285 Qib B yog thov hauv qhov qis - moders {{2} pa taws {2} kev sib pauv, muab cov vuam yooj yim uas tsis muaj preheing.
Hauv Is Nrias teb, nws muaj suab nrov rau cov khoom siv hluav taws xob ntxiv vim muaj tus nqi tsawg. Cov txiaj ntsig tau suav nrog kev them taus ntau dua- lub zog hlau thiab ua kom zoo rau cov mob me.
