ASTM, inozivikanwa seAmerican Society for Testing and Materials, isangano rine simba pasi rose remitemo rakatsaurirwa mukuvandudza nekuburitsa mitemo yemaindasitiri akasiyana-siyana. Mitemo iyi inopa nzira dzakafanana dzekuyedza, zvirevo uye gwara reindasitiri yeUS. Mitemo iyi yakagadzirirwa kuve nechokwadi chekuti zvigadzirwa nezvinhu zviri mumhando yepamusoro, mashandiro, uye kuchengetedzeka uye kuti kutengeserana kwenyika dzese kuve nyore.
Kusiyana-siyana uye kufukidzwa kwezviyero zveASTM kwakakura uye kunosanganisira nzvimbo dzakasiyana-siyana dzinosanganisira, asi kwete chete, sainzi yezvinhu, uinjiniya wekuvaka, chemistry, uinjiniya wemagetsi, uye uinjiniya wemakanika. Mitemo yeASTM inofukidza zvese kubva pakuedzwa nekuongororwa kwezvinhu zvakagadzirwa kusvika kune zvinodiwa nenhungamiro panguva yekugadzira chigadzirwa, kugadzirwa, uye kushandiswa.
ASTM A36/A36M:
Zvinodiwa zvesimbi zvinoenderana nezvinodiwa zvesimbi yekuvaka, kugadzira, uye mamwe mashandisirwo einjiniya.
Plate yesimbi yeA36Maitiro Ekusimbisa Mutemo
Muyero wekuita ASTM A36/A36M-03a, (zvakaenzana neASME code)
Ndiro yeA36shandisa
Mutemo uyu unoshanda kumabhiriji nezvivakwa zvine zvivakwa zvakasungirirwa, zvakasungirirwa uye zvakasungirirwa, pamwe chete nezvikamu zvesimbi yekabhoni yemhando yepamusoro, maplate nemabhawa. Plate yesimbi yeA36 inoburitsa goho muinenge 240MP, uye ichawedzera nekukora kwezvinhu izvi kuti goho riderere, nekuda kwehuwandu hwekabhoni huri pakati nepakati, kushanda kwayo kuri nani, simba, plasticity uye welding nezvimwe zvinhu kuti iwane match iri nani, ndiyo inonyanya kushandiswa.
Musanganiswa wemakemikari weplate yesimbi yeA36:
C: ≤ 0.25, Si ≤ 0.40, Mn: ≤ 0.80-1.20, P ≤ 0.04, S: ≤ 0.05, Cu ≥ 0.20 (kana zvinhu zvesimbi ine mhangura).
Hunhu hwemakanika:
Simba rekupa: ≥250.
Simba rekusimba: 400-550.
Kureba: ≥20.
Standard yenyika neA36 zvinhu zvakafanana neQ235.
