Q345 ASTMGr.50 ISOE355CC JISSN400 daawaha hoose ee xoogga sare ee tuubada birta ah
Sharaxaada Alaabta
Q345 waa nooc ka mid ah birta-daawaha hoose oo leh sifooyin farsamo oo dhammaystiran oo wanaagsan, guryaha heerkulka hooseeya, caagagga wanaagsan iyo alxanka.Waxaa loo isticmaalaa weelasha cadaadiska dhexdhexaadka ah iyo kuwa hooseeya, taangiyada saliidda, baabuurta, wiishashka, mishiinada macdanta, saldhigyada korontada, buundooyinka iyo dhismayaasha kale, qaybaha farsamada, dhismayaasha dhismaha iyo qaababka guud ee biraha ee culeyska firfircoon.Q345A, Q345B, Q345C, Q345D, Q345E.Sababta ugu weyn ayaa ah in heerkulka saameyntu uu ka duwan yahay.Heerka Q345A, maaha in la sameeyo saameyn;Q345B, 20 ℃ saamaynta heerkulka qolka;Q345C, saamaynta heerka 0;Q345D waa - saamaynta 20 darajo;Q345E waa - saamaynta 40 darajo.Heerkulka saameynta kala duwan, qiimaha saameyntu waa ka duwan yahay.Saxanka dhexdiisa, waxa iska leh taxanaha daawaha hoose.Maaddada alloy-ga hooseeya, maaddadan ayaa ah tan ugu caansan.Q345 waxa la odhan jiray 16Mn.Sababtoo ah hirgelinta heerka caadiga ah, saxan birta noocan oo kale ah ayaa loo oggol yahay in lagu keeno dulqaad taban.
