ASTM A514 Alloy Steel Plate
Igwe nchara A514 bụ otu alloys emenyụ na ọkụ nwere ọtụtụ uru na njirimara mara mma. Ọ nwere opekempe ike ntanye nke 100 ksi (689 MPa) yana opekata mpe 110 ksi (758 MPa). Efere sitere na inch 2.5 ruo 6.0 inch nwere ikike tensile a kapịrị ọnụ nke 90 ksi (621 MPa) na 100 - 130 ksi (689 - 896 MPa) kacha. A514 efere na-enyekwa ezigbo weldability, na ike na obere ikuku okpomọkụ. Ezubere otu ASTM A514 maka ọtụtụ ihe eji arụ ọrụ yana igwe na akụrụngwa. Agbanyeghị, ojiji a na-ejikarị bụ dịka igwe arụrụ arụ n'iwu ụlọ. Otu a nke ígwè, nke na-agụnye A517, alloy ígwè na-ejikọta ike kachasị mma, ike siri ike, nguzogide corrosion, mmetụta-abrasion na-eguzogide, na ogologo oge akụ na ụba.

ASTM A514 bụ nke a na-ejikarị dị ka ígwè arụpụtara na cranes na nnukwu igwe na-ebu ibu. Gnee steel ebuka zuru oke nke A514.
Nchịkọta:
A na-ejikarị eme ihe dị ka nchara nhazi na cranes ma ọ bụ nnukwu igwe na-ebu ibu, A514 na-enye ike dị elu na ihe eji eme ihe.
A na-akpọkwa T-1 ígwè.
Emenyụọ na iwe maka ike ka ukwuu.
Dị na klaasị asatọ: B, S, H, Q, E, F, A na P.
Dị na ọkpụrụkpụ efere dị arọ (inch 3 ma ọ bụ karịa).
Kwesịrị ekwesị na obere okpomọkụ. Nsonaazụ mmetụta Charpy maka ihu igwe akọwapụtara dị.
