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

I-EN39 S235GT kunye ne-Q235 zombini ngamabakala entsimbi asetyenziselwa iinjongo zokwakha.

I-EN39 S235GT ludidi lwentsimbi olusemgangathweni lwaseYurophu olubhekisa kukwakheka kweekhemikhali kunye neempawu zoomatshini zentsimbi.Iqulethe uMax.I-0.2% ye-carbon, i-1.40% ye-manganese, i-0.040% ye-phosphorus, i-0.045% isulfure, kunye ne-0.020% engaphantsi kwe-Al.Amandla okugqibela e-EN39 S235GT yi-340-520 MPa.

I-Q235, ngakolunye uhlangothi, inqanaba lentsimbi yaseTshayina.Ilingana ne-EN standard S235JR ibakala lentsimbi elisetyenziswa ngokuqhelekileyo eYurophu.Insimbi ye-Q235 inomxholo wekhabhoni we-0.14% -0.22%, umxholo we-manganese ongaphantsi kwe-1.4%, umxholo we-phosphorus we-0.035%, umxholo wesulfure we-0.04%, kunye nomxholo we-silicon we-0.12%.Amandla okugqibela e-Q235 yi-370-500 MPa.

Ngamafutshane, i-EN39 S235GT kunye ne-Q235 zinemixube yeekhemikhali ezifanayo kodwa iimpawu zoomatshini zahluke kancinci.Ukhetho phakathi kwezi zibini luxhomekeke kwisicelo esithile kunye neemfuno zeprojekthi.
