8. JIS Mechanical Structure Steel ọkwa nnọchite anya usoro

S + carbon ọdịnaya + koodu mkpụrụedemede (C, CK), bụ nke a na-egosipụta ọdịnaya carbon site na uru etiti × 100. Akwụkwọ ozi C: na-anọchi anya carbon. K: na-anọchi anya ígwè carburizing. Dịka ọmụmaatụ, ọdịnaya carbon carbon Rolled plate S20C bụ 0.18-0.23%.
Koodu nkwụsịtụ na iwe ọkụ nke mpempe akwụkwọ carbon na-ekpo ọkụ na-ekpo ọkụ na nchara nchara: steeti annealed bụ A, ọkọlọtọ quenching na tempering bụ S, 1/8 hardness bụ 8, 1/4 siri ike bụ 4, 1/2 isi ike bụ 2, na ike siri ike bụ 2. bụ 1.

Koodu nhazi ihu: D maka ịgbagharị matte na B maka ịgbagharị agbagharị na-egbuke egbuke. Dịka ọmụmaatụ, SPCC-SD na-anọchi anya ọkọlọtọ emenyụ na iwe ọkụ, matte finish rolling, nke a na-ejikarị akwa carbon oyi akpọrepu. Ihe atụ ọzọ bụ SPCCT-SB, nke na-anọchite anya akwụkwọ ikike carbon oyi na-atụ na-ekpo ọkụ na nhazi ọkụ na-egbuke egbuke, na-achọ ihe eji arụ ọrụ na-ekwe nkwa.
