Q235B simbi ndiro imhando yakaderera kabhoni simbi. Iyo yenyika standard GB/T 700-2006 "Carbon Structural Steel" ine tsanangudzo yakajeka. Q235B ndechimwe chezvinhu zvakajairika zvigadzirwa zvesimbi muChina. Iyo isingadhuri uye inogona kushandiswa mune zvakawanda zvigadzirwa zvisingade kuita kwepamusoro.
Nzira:
(1) Inoumbwa neQ + nhamba + yemhando yegiredhi chiratidzo + deoxidation chiratidzo. Nhamba yaro yesimbi inotaridzwa ne "Q" kumiririra goho resimbi, uye nhamba dzinotevera dzinomiririra kukosha kwegoho muMPa. Semuenzaniso, Q235 inomiririra kabhoni structural simbi ine goho poindi (σs) ye235 MPa.
(2) Kana zvichidikanwa, chiratidzo chegiredhi yemhando uye deoxidation nzira inogona kuratidzwa mushure meiyo simbi nhamba. Chiratidzo chegiredhi chemhando A, B, C, D. deoxidation nzira chiratidzo: F inomiririra simbi inofashaira; b Inomiririra simbi inouraya; Z inomiririra simbi inourawa; The TZ zvinoreva Special Kill Steel. Simbi yakaurayiwa inogona kunge isina chiratidzo chechiratidzo, kureva kuti, zvese Z neTZ zvinogona kusiiwa zvisina kunyorwa. Semuenzaniso, Q235-AF inomirira Kirasi A iri kufashaira simbi.
(3) Special-purpose carbon steel, senge simbi yebhiriji, simbi yengarava, nezvimwewo, inotora nzira yekutaura yecarbon structural simbi, asi inowedzera tsamba inoratidza chinangwa pakupera kwenhamba yesimbi.
