Magiredhi ekuumbwa, zvivakwa zvemakanika uye zvigadzirwa zvekugadzira zvinodzorwa nehuwandu hwepasi rose uye yenyika zviyero zvesimbi isina tsvina. Nepo iyo yekare AISI madhijiti matatu Stainless simbi yekuverengera system (eg 304 ne316) ichiri kunyanya kushandiswa pakurongwa kwemagiredhi esimbi isina tsvina, masisitimu matsva ekuronga akagadzirwa.
Aya masisitimu anosanganisira 1-tsamba + 5-manhamba yeUNS nhamba, seS30400, sekutsanangurwa kwazvinoitwa neSAE neASTM. Nyika dzeEurope dziri kutora maitiro akabatana eEuro. Nyika idzi dziri kutsiva kana kuchinjisa nyika yadzo mazinga kuti aratidze zviyero zveEuro. Mamwe mazita ari kutsiviwa anosanganisira yekare BS uye EN nhamba se304S31 uye 58E.
Mamwe magiredhi haafukidzwe nenhamba dzakajairwa uye anogona kuve magiredhi evaridzi kana kupihwa zita pachishandiswa zviyero zvezvigadzirwa zvehunyanzvi zvakaita sewaya yewelding.
Stainless simbi zviyero zvinotsanangurwa zvakadzama muBritish Stainless Steel Association "Guide to Stainless Steel Specifications", inozivikanwawo seBSSA "Blue Guide".
Tafura iri pazasi inoronga mhatsa yemagiredhi esimbi isina simbi, zita ravo rekare reBS, nhamba itsva yeUNS uye zita idzva reEN.
