Q420 pā kila

Q420 Steel Introduction
ʻO ke kila Q420 he kila kila Kina o Low Alloy High Strength Structural Steel, ʻO ka ikaika o ka hua he 420 MPa, ua hoʻāʻo ʻia nā ʻāpana me nā pahu kila 16mm anawaena a i ʻole nā ​​papa kila, a ʻo ka ikaika tensile he 520-680 Mpa, ʻo 7.85 g / /cm3. Wahi a GB/T 1591-2008, loaʻa iā Q420 5 mau pae maikaʻi: Q420A, Q420B, Q420C, Q420D a me Q420E. No ke kila kila Q420, haku mele a me nā waiwai mechanical, e ʻoluʻolu e ʻike i nā papa ma lalo.
Nā hiʻohiʻona a me nā mea hoʻohana
He kiʻekiʻe ka ikaika o ke kila Q420, ʻoi aku ka maʻamau a i ʻole ka normalized a me ka tempered state, me nā waiwai mechanical piha piha, hiki ke hoʻohana ʻia i nā moku nui, nā alahaka, nā mea hoʻokele mana, nā paila a me ke kiʻekiʻe kiʻekiʻe, nā kīʻaha kiʻekiʻe, nā mīkini hāpai, nā mīkini mining a 'ē aʻe nui welded structural'āpana.
