Ịmepụta na ọgwụgwọ okpomọkụ
Ịrụ ọrụ
AISI 4140 alloy steel nwere ezigbo machinability na ọnọdụ annealed.
Ịmepụta
AISI 4140 alloy ígwè nwere nnukwu ductility. Enwere ike ịmepụta ya site na iji usoro omenala na ọnọdụ annealed. Ọ na-achọ nrụgide ma ọ bụ ike maka imepụta n'ihi na ọ siri ike karịa ígwè carbon nkịtị.
ịgbado ọkụ
AISI 4140 alloy steel nwere ike welded site na iji usoro niile. Otú ọ dị, a ga-emetụta ihe ndị na-emepụta ihe nke ígwè a ma ọ bụrụ na a na-agbanye ya na ọnọdụ okpomọkụ na-ekpo ọkụ, a ga-emekwa ọgwụgwọ okpomọkụ nke post-weld.
Ọgwụgwọ okpomọkụ
AISI 4140 alloy steel na-ekpo ọkụ na 845 ° C (1550 ° F) na-esote ya na mmanụ. Tupu agbasie ike, enwere ike ịhazi ya site na kpo oku na 913°C (1675°F) ogologo oge, ikuku jụrụ oyi.
Na-akpụ akpụ
Akpụchara ígwè AISI 4140 na 926 ruo 1205°C (1700 ruo 2200°F)
Na-arụ ọrụ ọkụ
AISI 4140 alloy steel nwere ike ịdị ọkụ na-arụ ọrụ na 816 ruo 1038 ° C (1500 ruo 1900 ° F)
Na-arụ ọrụ oyi
AISI 4140 alloy steel nwere ike ịrụ ọrụ oyi site na iji usoro ọdịnala na ọnọdụ annealed.
Na-ewe iwe
AISI 4140 alloy steel na-annealed na 872°C (1600°F) sochiri ya nwayọọ nwayọọ n'ime ọkụ.
Iwe iwe
Enwere ike ịme ọkụ AISI 4140 alloy steel na 205 ruo 649 ° C (400 ruo 1200 ° F) dabere n'ogo ike siri ike achọrọ. Enwere ike ịbawanye ike nke ígwè ahụ ma ọ bụrụ na ọ nwere okpomọkụ dị ala. Dịka ọmụmaatụ, enwere ike nweta ike ike nke 225 ksi site na iwe ọkụ na 316°C (600°F), na ike ike nke 130 ksi nwere ike nweta site na iwe ọkụ na 538°C (1000°F).
Na-emesi ike
AISI 4140 alloy steel nwere ike sie ike site na ịrụ ọrụ oyi, ma ọ bụ kpo oku na imenyụ.
