ST52 ST52-3 S355JR S355J0 ʻO ka lāʻau kila paʻa paʻa poʻe
No St52 ke kila ikaika kiʻekiʻe haʻahaʻa, e pili ana me Kina he aha ka mea st52 e like me Q345B, a i ʻole 16mn a me Q345D.ʻO ka papa kila like ST52-3 S355JR S355J0.
Ua hoʻohana ʻia ka pahu kila i nā ʻano āpau, e like me ka mokulele, aerospace, hoʻokele, ikehu nuklea, ʻoihana kemika, ʻike uila, hana mīkini, petrochemical, automotive, mea hana a me ka mita, kamaʻilio, lawe ʻana, a me nā mea lapaʻau, etc.
