ASTM A283 vs ASTM A709: Musiyano Mukuru Mukuumbwa Kwemakemikari, Hunhu Hwemakanika, uye Mashandisirwo

Sezvo mari yekudyara muzvivakwa zvepasi rose iri kuramba ichikwira, makondirakiti, vagadziri vesimbi, nemapoka ekutenga vari kunyatsotarisa musiyano wekushanda pakati pemhando dzakasiyana dzesimbi.ASTM A283uyeASTM A709zviyero zviviri zvesimbi zvinoshandiswa zvakanyanya, chimwe nechimwe chine hunhu hwakasiyana maererano nekuumbwa kwemakemikari, hunhu hwemakanika, uye mashandisirwo. Chinyorwa chino chinopa kuenzanisa kwakadzama kwenyanzvi mukuvaka mabhiriji, zvivakwa zvekuvaka, uye mapurojekiti emaindasitiri.

ASTM A283: Simbi yeKabhoni Inoshanda Nemari Yakawanda

ASTM A283ipuratifomu yesimbi yesimbi inoshandiswa zvakanyanya mukuvaka nekugadzira zvinhu. Zvakanakira zvayo zvinosanganisira:

Inodhura zvishoma uye isingadhuri

Kugona kusundira zvakanaka uye kushanda zvakanaka

Yakakodzera kushandiswa kwechimiro chisina simba rakawanda

Magiredhi akajairika anosanganisira A283 Giredhi A, B, C, uye D, pamwe cheteGiredhi Cndiyo inonyanya kushandiswa. Mashandisirwo akajairika anosanganisira matangi ekuchengetera zvinhu, zvikamu zvekuvaka zvakareruka, mapurati ekuvaka akajairika, uye zvikamu zveinjiniya zvisiri zvakakosha.

Panyaya yemakemikari, A283 isimbi isina kabhoni yakawanda ine zvinhu zviri nyore uye isina alloying yekuwedzera, zvichiita kuti isadhure zvakanyanya asi isinganyanyi kusimba uye igare kwenguva refu.

ASTM A709: Simbi Yakasimba Yebhiriji

Kusiyana neizvi, ASTM A709 imhando yechiyero chesimbi yekuvaka chakagadzirirwa kuvaka mabhiriji, inoshandiswa zvakanyanya pamabhiriji emigwagwa mikuru nechitima, kusanganisira matanda makuru, matanda emuchinjikwa, mapurati edheki, uye zvivakwa zvetruss.

Magiredhi akajairika anosanganisira:

Giredhi 36 reA709

Giredhi 50 reA709

A709 Giredhi 50W (simbi inogadzirisa mamiriro ekunze)

HPS 50W / HPS 70W (simbi inoshanda zvakanyanya)

Zvakanakira zvikuru zveA709 zvinosanganisira:

Simba guru remushonga (≥345 MPa yeGiredhi 50)

Kusimba kwakanyanya kwekupisa kwakaderera kuneta uye kuramba kurova

Kusagona kudzorwa nemamiriro ekunze kuti kuderedze mari yekugadzirisa kwenguva refu

Simbi iyi inoshanda zvakanyanya inoita kuti A709 ive yakakodzera mabhiriji akareba, zvivakwa zvinorema, uye mapurojekiti anoda kugara kwenguva refu kubva mukuora kwemhepo.

Kuenzanisa Zvimiro zveMechanical

Pfuma ASTM A283 Giredhi C ASTM A709 Giredhi 50
Simba reGoho ≥ 205 MPa ≥ 345 MPa
Simba reKusimba 380–515 MPa 450–620 MPa
Kusimba Kwemhedzisiro Zviri pakati nepakati Yakanaka kwazvo (yakakodzera mabhiriji)
Kuramba Kwemamiriro Ekunze Zvakajairika Magiredhi emamiriro ekunze 50W/HPS

A709 inopa simba rakakwirira, kugara kwenguva refu, uye kusimba, zvichiita kuti ive yakakodzera kushandiswa mukuvaka kwakasimba uye kwakakosha.

Kufunga Nezvemutengo

Nekuda kwekuwedzera zvinhu zvekubatanidza uye zvinodiwa zvepamusoro zvekushanda,Kazhinji A709 inodhura kupfuura A283Kune mapurojekiti anochengetedza bhajeti shoma asi asingade zvivakwa zvakawanda, A283 inopa mari yakanakisa yekushandisa. Zvisinei, pakuvaka mabhiriji uye zvivakwa zvinotakura zvinhu zvakawanda, A709 ndiyo inonyanya kufarirwa kana kuti inorayirwa.

 

Nyanzvi dzeinjiniya dzinosimbisa kusarudza mhando yesimbi yakakodzera zvichienderana nezvinodiwa nechimiro pane mutengo chete.

Mapurojekiti asina mutoro wakanyanya, asingakoshi: A283 yakakwana.

Mabhiriji, zvivakwa zvinogara kwenguva refu, zvinhu zvinorema zvakanyanya, kana kusangana nenzvimbo dzakaoma: A709 inodiwa.

Nekukurumidza kwekuvandudzwa kwezvivakwa zvepasi rose, kudiwa kweASTM A709 kuri kuramba kuchikura, nepo A283 ichiri kuramba yakagadzikana mumisika yekuvaka nekuvaka matangi.
