Isu tese tinoziva Q235 uye Q345 zvinhu zviviri zvakakosha zvekutangira.
Iwe unoziva chii chisiyaniso chavo.
Q235Is simbi yakajeka yesimbi iyo inoshandiswa muChina. Izvo zvinozivikanwa zvakare seQ235A, Q235B, Q235c, uye Q235d. Sezvo iri simbi nyoro, inoshandiswa mukugadzirwa pasina kurapa kwekushisa. Iyo q inosarudza nzvimbo yekuzivisa, uye iyo 235 inoratidza simba rakabiwa.
Q345chinhu chesimbi. Iyo yakaderera-alloy simbi (c <0,2%), inoshandiswa zvakanyanya mumabhiriji, mota, ngarava, zvivakwa, kudzvanywa midziyo. Q inomiririra goho rezvinyorwa izvi, kuseri kweiyo 345, goho rinoreva kukosha kwezvinhu izvi, anenge 345. Uye vanozowedzera huwandu hwezvinyorwa uye kukosha kwaro kwakabereka kunoderera.
Q345A, Q345B, Q345C, Q345D, Q345E. Uku ndiko kusiyana kwekirasi kunomiririra kunyanya kukanganiswa kwekushisa kwakasiyana chete!
Q345A Chikamu, hazvisi zvekuvhunduka;
Q345B Giredhi ndeye makumi maviri madhigirii tembiricha tembiricha;
Q345c level, ndeye 0 degree maitiro;
Q345d Chikamu che -20 degree maitiro;
Q345E level ndeye -40 madhigirii.
Iko kukanganiswa kwekushisa kwakasiyana, kukosha kwekuvhundutsa kwakasiyana. Mundiro, iyo nyaya yakaderera-alloy matsvene. Mune yakaderera-alloy zvinyorwa uko kwakadaro zvinhu zvinonyanya kuitika.
