yintoni umahluko phakathi kwe-EN39 S235GT kunye ne-Q235?

I-EN39 S235GT kunye ne-Q235 zombini ziiklasi zentsimbi ezisetyenziselwa iinjongo zokwakha.

I-EN39 S235GT yinqanaba lesinyithi elisemgangathweni laseYurophu elibhekisa kwisakhiwo seekhemikhali kunye neempawu zoomatshini zesinyithi. Iqulethe i-Max. 0.2% yekhabhoni, i-1.40% ye-manganese, i-0.040% ye-phosphorus, i-0.045% yesalfure, kunye ne-0.020% ye-Al. Amandla okuxinana apheleleyo e-EN39 S235GT yi-340-520 MPa.

Kwelinye icala, i-Q235 yi-standard steel grade yaseTshayina. Ilingana ne-EN standard S235JR steel grade esetyenziswa kakhulu eYurophu. I-Q235 steel inomxholo wekhabhoni oyi-0.14%-0.22%, umxholo we-manganese ongaphantsi kwe-1.4%, umxholo we-phosphorus oyi-0.035%, umxholo wesulfure oyi-0.04%, kunye nomxholo we-silicon oyi-0.12%. Amandla okutsalwa kwe-Q235 yi-370-500 MPa.

Ngamafutshane, i-EN39 S235GT kunye ne-Q235 zineekhemikhali ezifanayo kodwa zineempawu zoomatshini ezahlukeneyo kancinci. Ukukhetha phakathi kwezi zimbini kuxhomekeke kwisicelo esithile kunye neemfuno zeprojekthi.
