Uyini umehluko phakathi kwe-EN39 S235GT ne-Q235?

I-EN39 S235GT kanye ne-Q235 zombili ziyizinhlobo zensimbi ezisetshenziselwa izinjongo zokwakha.

I-EN39 S235GT iyizinga lensimbi elijwayelekile laseYurophu elibhekisela ekwakhiweni kwamakhemikhali kanye nezakhiwo zemishini zensimbi. Iqukethe i-Max. 0.2% yekhabhoni, i-1.40% manganese, i-0.040% phosphorus, i-0.045% sulfure, kanye ne-Al engaphansi kuka-0.020%. Amandla okuqina aphezulu e-EN39 S235GT angama-340-520 MPa.

Ngakolunye uhlangothi, i-Q235 iyizinga lensimbi elijwayelekile laseShayina. Ilingana nezinga lensimbi elijwayelekile le-EN S235JR elivame ukusetshenziswa eYurophu. Insimbi ye-Q235 inokuqukethwe kwekhabhoni okungu-0.14%-0.22%, okuqukethwe kwe-manganese okungaphansi kuka-1.4%, okuqukethwe kwe-phosphorus okungu-0.035%, okuqukethwe kwe-sulfur okungu-0.04%, kanye nokuqukethwe kwe-silicon okungu-0.12%. Amandla okuqina aphezulu e-Q235 angama-370-500 MPa.

Ngamafuphi, i-EN39 S235GT kanye ne-Q235 zinezakhi zamakhemikhali ezifanayo kodwa izakhiwo zemishini ezihlukile kancane. Ukukhetha phakathi kwalokhu okubili kuncike ekusetshenzisweni okuqondile kanye nezidingo zephrojekthi.
