1.1 Plasticity
Plasticity ndiko kugona kwesimbi kuburitsa deformation yepurasitiki (permanent deformation) pasi pemutoro pasina kukuvara.
1.2 Kuoma
Hukukutu (hardness in English) chitaridzo chechiyero chekuoma kana kupfava kwesimbi.Iyo inonyanya kushandiswa nzira yekuona kuomarara mukugadzira ndiyo indentation kuomarara nzira, iyo inoshandisa indenter yeimwe geometry kudzvanya mukati meiyo yakaedzwa simbi zvinhu pasi pemumwe mutoro uye inotarisa kukosha kwayo kwekuoma zvinoenderana nechiyero chekutsikirirwa. mariri.
Nzira dzinowanzoshandiswa iBrinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) neVickers hardness (HV) nzira.
1.3 Kuneta
Iyo simba, plastiki uye kuoma kwakambokurukurwa zvese zvinongedzo kune mechaniki zvinhu zvesimbi pasi pe static load.Muchokwadi, akawanda muchina zvikamu zvinoshanda pasi pemitoro yecyclic, uye pasi pemamiriro ezvinhu akadai zvikamu zvinoburitsa kuneta.
1.4 Impact kuoma
Kuremerwa kunoshanda pachikamu chemuchina nekumhanya kwakakura kunodaidzwa kuti impact load, uye kugona kwesimbi kuramba kukuvara pasi pesimba remutsindo kunonzi kukanganisa kuoma.
1.5 Simba
Kusimba ndiko kuramba kwesimbi zvinhu kukuvadza (yakawandisa plastiki deformation kana kutyoka) pasi pemutoro wakamira.Sekuita kwemutoro muchimiro chekusimba, kudzvanya, kukotama, kugera, saka simba racho rakakamurwa kuita simba rekusimba, kusimba kwesimba, kukotama simba, kugera simba, nezvimwewo . kushandiswa kweiyo general tensile simba seyakanyanya kukosha simba chinongedzo.
Square chubhu inoshandiswa mukuvaka, kugadzira michina, mapurojekiti ekuvaka simbi, kuvaka ngarava, kutsigirwa kwesimba rezuva, simbi yekugadzira engineering, magetsi emagetsi, zvidyarwa zvemagetsi, zvekurima nemakemikari michina, girazi keteni madziro, mota chassis, airport, boiler kuvaka, njanji. , kuvakwa kwedzimba, midziyo yekumanikidza, matangi ekuchengetera peturu, mabhiriji, chiteshi chemagetsi midziyo, kusimudza uye michina yekufambisa uye mamwe marefu akashongedzwa zvikamu zvechimiro, nezvimwe.

Surface treatment classification
Square chubhu zvinoenderana nekurapwa kwepamusoro: inopisa dip galvanized square chubhu, electro galvanized square chubhu, oiled square chubhu, pickled square chubhu.
Shandisa classification
Square chubhu nekushandisa: yekushongedza sikweya chubhu, muchina midziyo square chubhu, muchina indasitiri square chubhu, makemikari indasitiri square chubhu, simbi chimiro square chubhu, shipbuilding square chubhu, mota square chubhu, simbi beam square chubhu, yakakosha chinangwa square chubhu.
Wall ukobvu classification
Square chubhu inokamurwa nemadziro emadziro: super gobvu madziro square chubhu, gobvu madziro square chubhu uye nhete madziro square chubhu.
