FAQ:
Qhov sib txawv ntawm SS400 thiab haiv neeg Q235b:
1. Hauv 16 hli Steel phaj piv txwv, cov paib lub zog ntawm SS400 steel phaj yog 10mpa siab dua li ntawm Q235a.
2. Lub tensile muaj zog thiab elongation yog siab dua li cov Q235a.
3. SS400 STEEL PHAJ yog tsim nyog rau choj, nkoj, thiab tsheb, thiab cov ntawv thov ntau ntawm cov SS400.
2. Dab tsi yog cov hlau me me?
Tsawg cov pa hlau (hlau me) yog cov hlau hlau nrog cov ntsiab lus carbon nrog tsawg dua 0. 25%. 25%. Nws tseem hu ua cov hlau me me vim tias nws lub zog qis, tsis muaj zog thiab softness. Nws suav nrog feem ntau cov hlau zoo tib yam ntxwv cov hlau thiab qee cov roj carbon ua kom zoo. Feem ntau ntawm lawv tau siv rau kev kho vaj tshuab Lub annealed qauv ntawm cov roj carbon steel yog ferrite thiab ib qho me me ntawm cov hlawsite. Nws lub zog thiab hardness yog tsawg, thiab nws cov yas thiab tawv yog qhov zoo.
3. Kev Xam ntawm Qhov Nyhav Ntawm SS400 Cov Qauv Hlau Hlau
Cov mis rau kev xam qhov hnyav ntawm SS400 steel phaj yog: tuab (hli) * Ntev * 7.85 (g / cm³) / 1000000
