DIN 2609 ST 35-8 Qib Seamless Yeeb Nkab yog ib qho tshwj xeeb ntawm seamless steel yeeb nkab, uas yog tus qauv raws li German Industrial Standard DIN 2609. Cov yeeb nkab seamless no belongs rau cov khoom siv zoo carbon steel, thiab nws cov tshuaj muaj pes tsawg leeg muaj xws li cov khoom siv tshwj xeeb. Cov ntsiab lus ntawm cov ntsiab lus xws li carbon, silicon, thiab manganese kom ntseeg tau tias nws cov khoom siv dag zog thiab corrosion kuj.
DIN 2609 ST 35-8 cov kav dej muaj lub zog tawm ntawm yam tsawg kawg 360MPa thiab lub zog tensile yam tsawg kawg nkaus ntawm 480MPa.
DIN 2609 Gr ST 35-8 cov kav dej muaj nyob rau hauv ntau txoj kab uas hla thiab phab ntsa thicknesses. Kuj tseem muaj cov kav dej welded thiab seamless, round, hydraulic, rectangular, square thiab lwm yam kav dej. Txhua hom yeeb nkab yog siv sib txawv hauv daim ntawv thov. Nws feem ntau yog siv nyob rau hauv high-pressure thiab high-temperature ib puag ncig xws li boilers thiab siab hlab ntsha.
