40Cr Alloy Structure Hlau
Siab -Strength Low Alloy (HSLA) Steel Phaj Product Description
40Cr alloy steel phaj yog ib qho ntawm cov qauv siv dav tshaj plaws. Vim nws cov khoom siv zoo, 40Cr cov ntaub ntawv hlau tau dav siv hauv kev tsim cov khoom tseem ceeb quenched thiab tempered mechanical qhov chaw, xws li iav bushings, txuas rods, screws, cua inlet li qub, nrog rau nruab nrab -cov yas pwm thiab pwm hauv paus kev lag luam pwm. Pwm structural qhov chaw.
Tom qab quenching thiab tempering kev kho mob, 40Cr Alloy Structure Steel Phaj muaj cov cuab yeej zoo txhua yam, tsis tshua muaj kub cuam tshuam toughness thiab qis rhiab heev.
Ntxiv rau qhov quenching thiab tempering, 40Cr alloy steel sheet hlau kuj tseem haum rau nitriding thiab siab - zaus quenching . 40Cr structural phaj muaj NMenability zoo, dej quenching tuaj yeem ncav cuag 28 ~ 60mm, thiab roj quenching tuaj yeem ncav cuag 15 ~ 40mm. Thaum quenching kub yog 174 ~ 229HBS, tus txheeb ze machinability yog 60%.
