Kodi kusiyana pakati pa EN39 S235GT ndi Q235 ndi kotani?

EN39 S235GT ndi Q235 zonse ndi zitsulo zomwe zimagwiritsidwa ntchito popanga.

EN39 S235GT ndi mtundu wa chitsulo wokhazikika ku Europe womwe umatanthauza kapangidwe ka mankhwala ndi mawonekedwe a chitsulocho. Chili ndi kaboni woposa 0.2%, 1.40% manganese, 0.040% phosphorous, 0.045% sulfure, ndi Al yochepera 0.020%. Mphamvu yolimba kwambiri ya EN39 S235GT ndi 340-520 MPa.

Koma Q235 ndi mtundu wachitsulo wokhazikika wa ku China. Ndi wofanana ndi mtundu wachitsulo wokhazikika wa EN S235JR womwe umagwiritsidwa ntchito kwambiri ku Europe. Chitsulo cha Q235 chili ndi kuchuluka kwa kaboni kochokera ku 0.14% mpaka 0.22%, kuchuluka kwa manganese kochepera 1.4%, kuchuluka kwa phosphorous kochokera ku 0.035%, kuchuluka kwa sulfure kochokera ku 0.04%, ndi kuchuluka kwa silicon kochokera ku 0.12%. Mphamvu yolimba kwambiri ya Q235 ndi 370-500 MPa.

Mwachidule, EN39 S235GT ndi Q235 zili ndi mankhwala ofanana koma zimakhala ndi makhalidwe osiyana pang'ono a makina. Kusankha pakati pa ziwirizi kumadalira momwe polojekitiyi ikuyendera komanso zofunikira zake.
