imuphi umehluko phakathi kwe-EN39 S235GT ne-Q235?

I-EN39 S235GT ne-Q235 womabili amabanga ensimbi asetshenziselwa izinjongo zokwakha.

I-EN39 S235GT iyizinga lensimbi elisezingeni laseYurophu elisho ukwakheka kwamakhemikhali kanye nezakhiwo zensimbi. Iqukethe i-Max. 0.2% carbon, 1.40% manganese, 0.040% phosphorus, 0.045% sulphur, futhi ngaphansi kuka-0.020% Al. Amandla okugcina we-EN39 S235GT angama-340-520 MPa.

I-Q235, ngakolunye uhlangothi, iyibanga lensimbi elijwayelekile laseShayina. Ilingana ne-EN standard S235JR grade yensimbi evame ukusetshenziswa eYurophu. Insimbi ye-Q235 inokuqukethwe kwekhabhoni engu-0.14% -0.22%, okuqukethwe kwe-manganese okungaphansi kuka-1.4%, okuqukethwe kwe-phosphorus okungu-0.035%, okuqukethwe kwesulfure okungu-0.04%, kanye ne-silicon engu-0.12%. Amandla okugcina we-Q235 angama-370-500 MPa.

Kafushane, i-EN39 S235GT ne-Q235 zinezakhi zamakhemikhali ezifanayo kodwa izakhiwo zemishini ezihluke kancane. Ukukhetha phakathi kwakho kokubili kuncike ekusetshenzisweni okuqondile kanye nezidingo zephrojekthi.
