ASTM A514 Giredhi T simbi ndiro

ASTM A514 inonyanya kushandiswa sesimbi yezvimiro mumacranes uye mahombe anorema-mutoro michina.

A514 ndiyo imwe mhando yesimbi yakasimba, iyo inodzimwa uye yakanyoroveswa alloy simbi, ine goho simba re100,000 psi (100 ksi kana anenge 700 MPa). The ArcelorMittal trademark zita rekuti T-1. A514 inonyanya kushandiswa sesimbi yekugadzira kuvaka kuvaka. A517 is a alloy yakanyatsoenderana iyo inoshandiswa pakugadzirwa kwepamusoro-simba rekumanikidza midziyo.

Uyu chiyero chakatarwa nesangano remayero reASTM International, masangano ekuzvidira ekusimudzira zviyero anoisa tekinoroji zviyero zvezvinhu, zvigadzirwa, masisitimu, uye masevhisi.

A514
Iko kusimba kwegoho reA514 alloys inotsanangurwa senge 100 ksi (689 MPa) yehukobvu hunosvika 2.5 inches (63.5 mm) gobvu ndiro, uye ingangoita 110 ksi (758 MPa) yekupedzisira kusimba kwesimba, ine yakatarwa yekupedzisira huwandu hwe. 110–130 ksi (758–896 MPa). Maplates kubva pa2.5 kusvika pa6.0 inches (63.5 kusvika 152.4 mm) akakora ataura kusimba kwe90 ksi (621 MPa) (goho) uye 100–130 ksi (689–896 MPa) (yekupedzisira).

A517
Simbi yeA517 ine simba rakaenzana regoho, asi rakati repamusoro rakatarwa simba rekupedzisira re115–135 ksi (793–931 MPa) pakukora kusvika 2.5 inches (63.5 mm) uye 105–135 ksi (724–931 MPa) pakukora 2.5 kusvika 6.0 inches (63.5 kusvika 152.4 mm).

Usage
Masimbi eA514 anoshandiswa uko inokwenenzverwa, inokwenenzverwa, yakasimba kwazvo simbi inodiwa kuchengetedza uremu kana kusangana nezvinodiwa zvesimba rekupedzisira. Inowanzo shandiswa sesimbi yezvimiro mukuvaka zvivakwa, cranes, kana mamwe machina mahombe anotsigira mitoro yakakwira.

Uye zvakare, masimbi eA514 anotsanangurwa nemaitiro echiuto (ETL 18-11) kuti ashandiswe sediki-maoko ekupfura siyana mabhafu uye deflector mahwendefa.

Mechnical pfuma yeA514GrT alloy simbi:

Kemikari yakagadzirwa yeA514GrT alloy simbi (Heat Analysis Max%)

Zveunyanzvi Zvinodiwa & Mamwe Masevhisi:

• High tension test
• Low tembiricha inokanganisa bvunzo
• Simulated post-welded heat treatment (PWHT)
• Yakabudiswa Orginal Mill test certificate pasi pe EN 10204 FORMAT 3.1/3.2
• Kana cooper simbi inotsanangurwa yeA709 Gr36, zviri mukati Cu≥0.20%
• Shot blasting uye Painting, Kucheka uye welding sezvinodiwa nemushandisi wekupedzisira
• Huremu hunorema (3-inches kana kukora) inowanikwa munzvimbo zhinji dzeLeeco Steel yekugovera.
• Inowanikwa mumagiredhi akajairwa: 36, 50 uye 50W.
• Inowanikwa mumagiredhi epamusoro-soro: HPS 50W uye HPS 70W.
• Vatengi vanogona kutsanangura mamakisi eA709 kusangana neCharpy bvunzo inodiwa kune yakatarwa nzvimbo uye mamiriro ekunze.
