Mapaipi esimbi echimiro cherectangular DIN 17100 St52.3 akatumirwa kuAustralia.
DIN 17100 inoshandiswa pazvikamu zvesimbi, simbi, waya, zvigadzirwa zvakati sandaramusonouye zvikamu zvakasungirirwa, zvikwere uye zverectangular zvisina chinhu, maforging, uye zvigadzirwa zvakapedzwa zvishoma musimbi dzekuvaka dzinoendeswa mumamiriro ezvinhu anopisa kana akajairwa mushure mekugadzirwa.
St52.3 ndeimwe yemagiredhi, uye nhamba yezvinhu ndeye 1.0570.
Botop isati yasvika, inoronga kuti vashandi vehunyanzvi vane hunyanzvi vaongorore zvigadzirwa nokungwarira kuti ive nechokwadi chekuti mhando yechigadzirwa inosangana zvizere nezvinodiwa nevatengi.
Chekutanga, hunhu hwepamusoro, hupamhi, kukwirira, kureba, sikweya, nezvimwe zviyero zvechitarisiko chepombi yesimbi yechimiro zvinoongororwa nokungwarira kuti zvive nechokwadi chekuti zvinoenderana nezvinodiwa nevatengi.
Zvadaro, hunhu hwemakemikari uye hwemakanika hwepombi yesimbi yekuvaka hunoongororwa.
EN 17100 St52.3 ine zvinodiwa zvinotevera pakuumbwa kwemakemikari:
| Giredhi | Kuumbwa kwemakemikari mu% ne wt. | ||||||||
| C | P | S | Zvimwe zvinhu zvinosanganisa nitrogen (semuenzaniso 0.020% Al kusvika pahuwandu hwese) | ||||||

Kuumbwa kwemakemikari eSt52.3 kunoyerwa nespectrometer, uye zvese zviri mukati mechinhu zvinosangana nezvinodiwa nevatengi zvichienzaniswa nezvinodiwa.
Hunhu hwemakanika hweEN 17100 St52.3 hunonyanya kusanganisira simba rekudhonza uye simba rekuburitsa simba, izvo zvinoyerwa nekuyedza kwekudhonza.

Mushure mekupedza kuongorora kwese uye kuona kuti mhando yacho inoenderana nezvinodiwa, Chitupa Chekuyedza Zvinhu (MTC) chinopihwa. Mushure mezvo, gadziriro dzinoitwa dzekutumira zvinhu nezvimwe zvine chekuita nazvo.
Kubva payakavambwa muna 2014, Botop Steel yave kambani inotungamira mukutengesa mapaipi esimbi yekabhoni kuchamhembe kweChina, inozivikanwa nebasa rayo rakanaka, zvigadzirwa zvemhando yepamusoro, uye mhinduro dzakakwana.
Paodha yega yega, Botop inogara ichitevedzera hurongwa hwemhando yepamusoro uye mitengo yakanaka, ichitisarudza kuti tikupe zvigadzirwa zvemapaipi esimbi zvakavimbika.
