DIN 17100 St52.3 rectangular structural steel pombi dzakatumirwa kuAustralia.
DIN 17100 yakajairwa inoshandiswa kune zvikamu zvesimbi, simbi mbariro, waya tsvimbo, flat zvigadzirwaisina musonouye akasungwa, akaenzana uye ane rectangular hollow zvikamu, forgings, uye semi-apedzwa zvigadzirwa mune zvakajairwa zvimiro zvesimbi izvo zvinounzwa mune inopisa inoumbwa kana yakajairwa mamiriro mushure mekugadzirwa.
St52.3 ndeimwe yemagiredhi, uye nhamba yezvinhu ndeye 1.0570.
Isati yatumirwa, Botop inoronga kuti vashandi vemhando yepamusoro vanyatso ongorora zvigadzirwa kuti vaone kuti mhando yechigadzirwa inonyatsozadzisa zvinodiwa nevatengi.
Chekutanga, mhando yepamusoro, hupamhi, urefu, kureba, squareness, uye zvimwe zvimiro zvechimiro chesimbi pombi inotariswa zvakanyatsonaka kuti ive nechokwadi chekutevedzera zviyero uye zvinodiwa nevatengi.
Zvadaro, kemikari uye michina yepombi yesimbi yekugadzira inotariswa.
EN 17100 St52.3 ine zvinotevera kuumbwa kwemakemikari zvinodiwa:
| Giredhi | Kuumbwa kwekemikari mu% ne wt. | ||||||||
| C | P | S | Yekuwedzera nitrogen inosanganisa zvinhu (semuenzaniso ingangoita 0.020 % Al kusvika tal) | ||||||

Iyo kemikari yeSt52.3 inoyerwa ne spectrometer, uye zvese zvirimo zvinosangana nezvinodiwa nevatengi zvichienzaniswa nezvinodiwa.
Iyo mechanic zvimiro zve EN 17100 St52.3 inonyanya kusanganisira kusimba kwesimba uye goho simba, izvo zvinoyerwa nekutemesa kuyedzwa.

Mushure mekupedza ongororo dzese uye nekuona kuti mhando inosangana nezvinodiwa, Chitupa Chekuita Chete (MTC) chinopihwa. Zvadaro, gadziriro dzinoitwa dzekutumira uye mabasa anoenderana.
Kubva payakavambwa muna 2014, Botop Steel yave mutengesi anotungamira wekabhoni simbi mapaipi kuchamhembe kweChina, inozivikanwa nebasa rayo repamusoro, zvigadzirwa zvemhando yepamusoro, uye mhinduro dzakakwana.
Pakurongeka kwega kwega, Botop inogara ichiomerera kune zano remhando yakavimbika uye mitengo yakanaka, kusarudza isu kuti tikupe iwe yakavimbika simbi pombi zvigadzirwa.
Nguva yekutumira: Oct-11-2024
