Q235 steel muaj zoo plasticity, toughness thiab weldability, nrog rau ib tug nruab nrab lub zog, zoo txias dabtsi yog khoov kev ua tau zoo. Q235 cov khoom siv feem ntau yog dov rau hauv cov hlau pas nrig lossis cov hlau puag ncig, square steel, tiaj tus hlau, lub kaum sab xis steel, kuv nqaj, channel steel, lwm ntu thiab cov hlau phaj. Cov khoom no tau siv dav hauv kev tsim kho thiab engineering welded cov qauv, ua cov hlau tuav lossis tsim cov tsev tsim khoom, cov khoom siv hluav taws xob siab, txuas hniav, tsheb, boilers, ntim, thiab lwm yam, thiab tseem siv los ua cov khoom siv nrog kev ua haujlwm tsawg dua xws li tsawg zog rods, txuas rods, screws, ceev, ferrules, brackets, thiab sawv, thiab lwm yam.
Lub cev muaj zog
Nco tseg:
10-6·K-1 = 10-6/K
1 Ω·mm²/m=1 μΩ·m
1 g/cm 3=1 kg/dm 3=1000 kg/m3
1 GPa=1 kN/mm2
1 MPa=1 N/mm2
