ASTM A514 ọkwa K ígwè efere

A na-eji ASTM High mkpụrụ ike ígwè efere A514 ọkwa K ebe a chọrọ weldable, machinable, nnukwu ike ígwè iji chekwaa ibu ma ọ bụ izute ike kacha mkpa. Alloy steel plate A514 Gr K na-ejikarị dị ka ihe nhazi nchara na-ewu ụlọ, cranes, ma ọ bụ nnukwu igwe ndị ọzọ na-akwado ibu dị elu. Ruo ugbu a, anyị nwere ike na-enye kacha ọkpụrụkpụ maka elu ike ígwè efere A514 Gr.K iru 300 millimeters na okpomọkụ ọgwụgwọ nke quenched na iwe.

ASTM A514 Structural Steel Plate bụ efere igwe na-ada n'okpuru nche anwụ nke Quenched na Tempered Alloy steel plates. Efere ndị a na-enweta ọgwụgwọ Q&T nke a na-ekpo ọkụ ma dị jụụ ngwa ngwa. Opekempe mkpụrụ nke 100 ksi na-eme ka ASTM A514 abrasion nchara na-eguzogide ọgwụ siri ike ma jiri ya mee ihe kwesịrị ekwesị. N'ikwekọ na ụkpụrụ ASTM, efere ígwè ndị a dị elu (HSA) na-anọchi anya:

S = Steel Structural
514 = ike mkpụrụ kacha nta
Q = emenyụ na iwe
A, B, C, E, F, H, J, K, M, P, Q, R, S, T= akara ule

Ngwongwo igwe maka A514 Gr K igwe siri ike:

Ngwakọta kemịkalụ maka A514 Gr K nnukwu ike ígwè (Heat Analysis Max%)

Ihe chọrọ nka na ụzụ na ọrụ ndị ọzọ:

• Nnwale esemokwu dị elu
• Nnwale emetụta ọnọdụ okpomọkụ dị ala
• Ngwọta okpomoku nke welded post-welded (PWHT)
