WstE500 saxan bir ah

Marka loo eego EN 10025-2, saxanka birta S275J2 waxaa inta badan loo isticmaalaa warshadaha dhismaha iyo injineernimada makaanikada, weelasha, taangiyada iyo astaamaha birta duuban sida birta xagasha, qaab dhismeedka birta, H-beam, T-qaybta. S275J2 birta kaarboonka, haddii macaamiishu rabaan inay hagaajiyaan waxqabadka birta marka la isticmaalayo, injineeradayadu waxay wali ku talinayaan inay caadi ka dhigaan daaweynta kulaylka. Haddii kale, birta waa in lagu sameeyaa tijaabada saamaynta heerkulka hoose ee -20 ° C.

DIN WstE500 saxan bir ah, sida ka kooban kiimikaad, waxa ku jira kala duwan ayaa inta badan ku jira ka kooban carbon, halka content ka carbon waa A283Gr. d aan ka badnayn 0.27%, kana sarreeyo darajada C (≤0.24%); Marka la eego sifooyinka farsamada, farqigu waa xoogga xajinta iyo wax-soo-saarka, halka ASTM A283 Gr.D ay leedahay xoogga xajinta ee 415-550MPa (60-80 ksi) iyo ASTM A283 D darajada ayaa leh awoodda wax-soo-saarka 230MPa (33 ksi). ).
