Q345D po'lat va Q355D po'lat o'rtasidagi farq
Q345 po'lat - Xitoy standartidagi past qotishma yuqori quvvatli strukturaviy po'lat bo'lib, "Q" belgisi oqish quvvatini va minimal oquvchanlikni ko'rsatadigan raqam. Q345 po'latdan yaxshi mexanik xususiyatlar, past harorat ko'rsatkichlari, plastiklik va payvandlanish qobiliyati mavjud. U ko'priklar, transport vositalari, kemalar, binolar, bosimli idishlar va boshqalarda keng qo'llaniladi.
Q345 po'latining kimyoviy tarkibi odatda uglerod, kremniy, marganets, fosfor, oltingugurt, xrom, nikel va boshqa mikroelementlar kabi elementlarni o'z ichiga oladi. Uning oquvchanligi qalinligi va issiqlik bilan ishlov berish sharoitlariga qarab, odatda 345 MPa va 500 MPa orasida. Q345 po'latining kuchlanish kuchi 470 MPa dan 630 MPa gacha bo'lishi mumkin.
Q345D po'lat vaQ355D po'lat Xitoyning past qotishmali yuqori quvvatli strukturaviy po'latning ikkala navi bo'lib, asosiy farq ularning oquvchanligidir.
Q345D po'latining oquvchanligi 345 MPa, Q355D po'latining oquvchanligi 355 MPa. Bu shuni anglatadiki, Q355D po'lati bir oz yuqori rentabellikga ega va odatda Q345D ga qaraganda kuchliroq material hisoblanadi.
Kimyoviy tarkibi jihatidan po'latning ikkala navi ham o'xshash va uglerod, kremniy, marganets, fosfor, oltingugurt, xrom, nikel va boshqa iz elementlari kabi elementlarni o'z ichiga oladi. Ular, shuningdek, yaxshi mexanik xususiyatlarga ega, past haroratda ishlash, plastiklik va payvandlanish qobiliyatiga ega.
Q345D va Q355D po'latlari odatda ko'priklar, binolar, transport vositalari va mexanizmlar kabi turli xil ilovalarda qo'llaniladi. Ikkalasi o'rtasidagi tanlov dasturning o'ziga xos talablariga va kerakli quvvat darajasiga bog'liq bo'ladi.
