STKM11A STKM14B steel raj rau lub tsheb
Specification
STKM11A yog qib steel rau carbon steel kav siv hauv cov khoom siv kho tshuab, tau los ntawm tus qauv JIS G3445, thiab yog qib Japanese.STKM11A steel yeeb nkab qib, cov khoom sib npaug rau SPHC, σ B ≥ 290MPa;Cov pa roj carbon steel rau STKM txhua yam qauv;
SPHC hom yog Ameslikas hom German thiab kuj tau siv nyob rau hauv Nyiv.Tom qab ntawd, nws tau qhia los ntawm lub tsev steel zeb Baosteel, sawv cev rau cov hlau kub dov (uas sib haum rau SPCC), sib npaug rau cov ntawv kub dov ntawm 10 # thiab 15 # steel hauv lub teb chaws tus qauv GB699 (National Standard for High Quality. Carbon Structural Steel), nrog rau cov ntsiab lus carbon ntawm ib ncig ntawm 0.1% -0.15%
Kev kho deg:
1. Bared
2.Black Painted (cov kua roj vanish txheej)
3. Galvanized
4. Yog '
5.Raws li cov neeg siv khoom.
JIS STKM11A ~ 18C / DIN ST52 / ASTM A106, precision thiab nto roughness ntawm txias kos precision steel kav nrog puab thiab txheej diameters superior rau kub dov kav.Cov kev qhia tshwj xeeb tuaj yeem hloov kho kom tau raws li qhov xav tau siab dua rau lub zog tensile, lub zog tawm los, elongation, thiab lwm yam;Cold drawn precision steel kav nrog puab thiab sab nraud diameters yuav siv tau rau pneumatic thooj voos kheej kheej;Roj siab lub tog raj kheej;Motorcycle thiab tsheb kauj vab shock absorbable;Cua txias condenser;Locomotive pem hauv ntej diav rawg thiab rear diav rawg;Mechanical caj npab;Zaj duab xis recycling granular;Cov yeeb nkab;Lub raj mis tshuab tshuab;Leveling tshuab;Jack;Cultivator;Roller rau tshuab luam ntawv, thiab lwm yam.
JIS G3445 Precision steel hlab yog tsuas yog siv nyob rau hauv tsheb thiab precision machinery qhov chaw rau tsheb thiab lub tog raj kheej.kev siv siab, thiab tseem siv rau kev thauj cov chav, dej, cov kav dej.
