DIN 17175 Seamless Steel Tubes Rau Kev Kub Siab Cov lus piav qhia
ST35.8 yog qib steel raws li DIN 17175 tus qauv, sib haum rau Suav tus qauv GB 8163, nrog rau qib khoom ntawm 10 # steel. ST35.8 steel kav muaj qhov zoo tshaj plaws weldability, ductility, thiab txias dabtsi yog khoov zog, ua rau lawv siv dav hauv dav dav - lub hom phiaj cov kav dej ua haujlwm.
ST35.8 seamless steel yeeb nkab yog cov khoom siv carbon steel hauv German DIN tus qauv. Nws cov tshuaj muaj pes tsawg leeg yog tswj nrog cov ntsiab lus carbon ntawm 0.17% -0.24%, silicon cov ntsiab lus ntawm 0.10% -0.35%, thiab manganese cov ntsiab lus ntawm 0.40% -0.80%, thaum nruj me ntsis txwv cov ntsiab lus ntawm cov teeb meem xws li sulfur thiab phosphorus. Qhov kev sib piv kev tshawb fawb no muab cov khoom siv nrog cov yas deformation zoo heev thiab weldability. Hais txog cov khoom siv kho tshuab, ST35.8 seamless steel yeeb nkab ua tiav lub zog tensile ntawm 360-480 MPa, lub zog tawm los ntawm tsis pub tsawg dua 235 MPa, thiab tswj kev elongation ntawm ntau dua 25%, ua tau raws li qhov yuav tsum tau muaj zog rau feem ntau cov ntawv thov kev lag luam.
DIN 17175 St35.8 Seamless Steel Tubes Chaw tsim tshuaj paus
Nyob rau hauv cov nqe lus ntawm ntau lawm technology, ST35.8 seamless steel kav yog tsim los siv kub dov thiab txias txheej txheem. Cov txheej txheem kub dov suav nrog cua kub ntawm qhov cub kom txog 1200℃rau kev tho thiab dov, uas yog qhov ua tau zoo thiab tsim nyog rau ntau lawm. Cov txheej txheem kev kos duab txias, ntawm qhov tod tes, suav nrog kev kos cov yeeb nkab steel ntawm chav tsev kub los ntawm adies, ua rau muaj qhov tseeb dua qhov tseeb thiab zoo dua nto tiav, txawm tias ntawm tus nqi ntau dua. Tsis hais txog ntawm cov txheej txheem, kev tshuaj xyuas online nruj thiab kev tswj xyuas zoo, suav nrog kev kuaj ultrasonic, eddy tam sim no kuaj, thiab kuaj hydrostatic, yog siv los xyuas kom meej tias txhua cov yeeb nkab steel ua tau raws li tus qauv yuav tsum tau ua. GNEE Group muaj peev xwm ua tau ST35.8 seamless steel kav hauv ntau qhov ntau thiab tsawg, xws li 6mm txog 1200mm inch, catering rau cov kev xav tau ntawm kev lag luam sib txawv.
