Q355Dumumiy tuzilmalar va muhandislik uchun past-qotishma yuqori-konstruktiv po'lat plitalar.
Amalga oshirish standarti: GB/T1591-2018.
Po'lat plitaning nomi "yi" so'zini ifodalovchi Xitoy pinyinidagi birinchi Q harfidan iborat bo'lib, "yi" so'zini ifodalaydi, belgilangan minimal yuqori rentabellik kuchi qiymati, kesishish To'rt qismdan iborat: yuk holati kodi va sifat darajasi (B, C, D, E, F).
Q355NEpast{0}}qotishma yuqori-po'latdir.
Amalga oshirish standarti: GB / T1591-2018, bu erda "Q" oqish quvvatini bildiradi, 355 bu po'latning oquvchanligi 355MPa, Q355A darajasi, ta'sir qilmaydi; Q355B darajasi, 20 daraja Oddiy harorat ta'siri; Q355C darajasi, 0 daraja ta'sir; Q355D darajasi, -20 daraja ta'sir; Q355E darajasi, -40 daraja ta'sir. Po'lat plastinka qalinligi yo'nalishi xususiyatlariga ega bo'lishi kerak bo'lganda, po'lat naviga qalinlik yo'nalishini (Z yo'nalishi) ishlash darajasini ifodalovchi belgi qo'shiladi. Q355NE dagi N normallashtiruvchi prokat yoki normalizatsiyani ifodalaydi.
