1.7220 plug taub hau yog ib series ntawm Hengdisheng Piercing mandrels. Qib 1.7220 yog alloy structural steel sau los ntawm European tus qauv EN 10083-3-2006. Cov kws tshaj lij feem ntau xaiv 1.7220 rau qhov kub thiab txias ua haujlwm siab, vim nws cov cuab yeej siab ntawm quenching thiab siab kub. Qhov no yog cov khoom siv ntau heev siv los ua cov khoom siv hauv cov tshuab hnyav, kev lag luam petrochemical, kev lag luam pib, thiab lwm yam.

Mechanical zog ntawm 1.7220 plug taub hau txawv ntawm qhov ntev:

txoj kab uas hla (mm):	rau 16	16 - 40	40 - 100	100 - 160	160 - 250
Rm - Tensile zog (MPa) (+ QT)	1000-1200	900-1100	800-950	750-900	700-850
Re - Upper yield zog los yog R_p0.2- 0.2% pov thawj lub zog (MPa) (+ QT)	800	650	550	450-500	410-450
A - Min. elongation Lo=5,65 √ Yog li (%) (+QT), puag ncig cov khoom	11	12	14	15	15
