Tsawg -} alloy thiab siab {1} {} Lub zog Steel phaj (SS490)

1. Txheej txheem cej luam dav dav

SS490 yog hom tsawg -} ally high- lub zog steel phaj dav siv nyob rau hauv cov ntawv thov txheej txheem. Cov "SS" nyob rau hauv nws cov qauv feem ntau sawv rau "cov hlau qauv txheem," thaum "490" qhia qhov tsawg kawg nkausLub zog tensilentawm 490 MPa. Cov hlau no yog paub txog nws qhov sib xyaw ua ke ntawm lub zog, ductility, thiab weldability, ua rau nws haum rau ntau txoj haujlwm kev tsim kho thiab kev tsim kho.

2. Cov Qauv thiab Cov Lus Qhia Tshwj Xeeb

Cov Qauv Japanese: SS490 feem ntau tau teev nyob rau hauv tus qauv Japanese muaj (JIS), tshwj xeeb hauvJIS G3101(Kub {- rolled steel daim hlau, ntawv txheeb, thiab ib daim ntawv rau cov qauv kev siv dav dav).

3. Tshuaj Muaj Tshuaj

Thaum cov muaj ntau yam muaj sib txawv los ntawm cov chaw tsim tshuaj paus thiab cov qauv, tshuaj lom neeg cov khoom siv hauv SS490 suav nrog:

 

Lub ntsiab	Cov ntsiab lus ntau (%)	Lub luag hauj lwm
Carbon (c)	Tsawg dua los yog sib npaug rau 0.20	Sib npaug muaj zog thiab ductility; Cov ntsiab lus qis dua kev txhim kho weldability.
Silicon (si)	Tsawg dua los yog sib npaug rau 0.55	Deagidizer; Txhim kho lub zog me ntsis.
Manganese (mn)	0.60–1.50	Txhim kho lub zog thiab cov tawv tawv; AIDS hauv DEIGHIDATION.
Sulphur (s)	Tsawg dua los yog sib npaug rau 0.045	Tswj kom txo qis brittleness thiab kub tawg.
Phosphorus (p)	Tsawg dua los yog sib npaug rau 0.045	Tswj tau kom txo qhov txias brittleness.
Alloying Ntsiab	Qaum (piv txwv li, Cu, Ni, CR rau corrosion tsis kam nyob hauv qee qhov sib txawv)	Txhim kho cov khoom tshwj xeeb xws li 耐腐蚀性 (corrosion tsis kam).
