The main difference is that P500Q steel has a lower minimum yield strength (500 MPa) compared to P690Q (>690 MPa), bu ham P500Q uchun minimal kuchlanish kuchiga olib keladi. Ikkalasi ham EN 10028-6 standartiga muvofiq bosimli idishlar uchun so'ndirilgan va qattiqlashtirilgan po'lat plitalardir, ammo P690Q yuqori quvvatli sinfdir.
