300Lus® Pfc Channel Hlau Cov Ntawv Sib Tw (rau ib li / NZS 3679.1) yog qhov zoo tshaj rau Australian tej yam kev mob:
Cov pa roj carbon (c): Max 0.25%- Muab lub zog ua kom muaj zog tab sis yog tsawg kom tsis txhob brittleness thiab kom ntseeg tau weldability. Ntau dhau ntawm cov pa roj carbon ntau dhau yuav ua rau muaj kev pheej hmoo ntau zaus hauv kev sib tw hauv cov huab cua thoob plaws hauv Australian.
Manganese (MN): 1.00-1.60%- Lub zog tseem ceeb, tsim cov kev daws teeb meem nrog cov hlau los txhawb cov txiaj ntsig / tensile lub zog. Nws kuj tseem txhim kho cov kev nyuaj thiab txo qis "kub luv luv" (dov tawg).
Silicon (si): 0.15-0.40%- Deasoxidizes molten hlau, txhim kho cov suab lus thiab tiv taus corrosion los ntawm Australia cov ntug dej hiav txwv cua.
Phosphorus (p): Max 0.035%- Tshuaj tiv thaiv kom tiv thaiv qis qis - kub ua kom qhov txias (tseem ceeb rau yav qab teb Australian winters).
Sulphur (s): Max 0.035%- Tsawg tsawg kom tsis txhob muaj hlau hlau los ntawm kev tsim cov ntaub pua chaw, uas ua rau muaj zog 300 txog li 350-600 mpa tensile lub zog, thiab 22% yam tsawg kawg nkaus elongation.
