Hauv kev ua lag luam qub, cov txheej txheem xws li carbon steel, stainless hlau, thiab tooj.
Ib cov pa hlau. Peb paub cov roj tsawg, cov pa roj carbon nrab thiab cov pa roj carbon fiber ntau, thiab cov hlau phom hlau los ntawm carbon cov ntsiab lus.
1 Low-carbon steel C% ≤ 0.25% Domestically npe hu ua A3 steel. Yeej paub tias txawv teb chaws li 1008,1015,1018,1022 thiab hais txog. Feem ntau yog siv rau 4.8 bolts thiab 4 ceev, screws me me thiab lwm yam khoom uas tsis muaj qhov yuav tsum ua. (Faj seeb: Lub tshuab drilling yog ua los ntawm 1022 khoom.)
2 Nruab nrab steel 0.25%
3 Cov pa roj carbon c%> 0.45%. Tam sim no tsis siv nyob hauv kev ua lag luam
4 Hlau Cov Hlau: Ntxiv cov ntsiab ntawm cov hlau mus qaum cov pa hlau kom qee cov khoom tshwj xeeb ntawm cov hlau: 35, 40 chrome molybdenum, SCM435, 10B38. Fang Sheng txhuam tsuas yog siv SCM435 chromium molybdenum alloy hlau, lub ntsiab Cheebtsam yog C, Si, Mn, P, S, Cr, Mo.
Ob zaug steel hlau. Kev kawm theem: 45, 50, 60, 70, 80
1 Feem ntau cov khoom siv (18% Cr, 8% Ni) muaj kev tiv thaiv tshav kub zoo, tiv thaiv kev txhim kho zoo, thiab zoo weldability. A1, A2, A4
2 Martensite thiab 13% Cr muaj tsis muaj zog corrosion, siab zog thiab zoo coj kuj. C1, C2, C4 ferritic stainless hlau. 18% Cr forging cov cuab yeej zoo, corrosion kuj yog muaj zog tshaj martensite. Cov khoom lag luam nyob hauv kev lag luam mas Japanese khoom. Raws li qib tau muab faib SUS302, SUS304, SUS316.
Peb tooj. Feem ntau siv cov ntaub ntawv rau tooj dag ... zinc copper alloy. Lub khw tsuas yog siv H62, H65, H68 tooj liab raws li kev cai.
