Dab tsi ntawm seamless steel yeeb nkab yog qib 34CrMo4?
34CrMo4 yog cov khoom siv chromium-molybdenum steel hlau, uas yog siv los tsim seamless steel yeeb nkab cov ntaub ntawv rau dov lub tog raj kheej / lub tog raj kheej thiab cov hlab ntsha siab.
Cov tshuaj muaj pes tsawg leeg ntawm 34CrMo4 cov khoom: C: 0.30~0.37 Si: Tsawg dua lossis sib npaug rau 0.4{{10 }} Mn: 0.60~0.90 P, S: Tsawg dua lossis sib npaug rau 0.020 P + S: Tsawg dua lossis sib npaug rau 0.030 Cr: 0.90 ~ 1.20 Mo: 0.15 ~ 0.30 Ni: Tsawg dua lossis sib npaug rau 0.30 Cu: Tsawg dua lossis sib npaug rau 0.20
Cov qauv kev siv dav dav rau seamless steel kav rau 34CrMo4 roj thooj voos kheej kheej: lub teb chaws tus qauv GB / T 18248-2021, Nyiv tus qauv JIS G 3429, tus qauv thoob ntiaj teb ISO 11120, European tus qauv EN 10297-1, Asmeskas tus qauv ASTM A372 / A372M{ {8}}
Cov khoom siv hluav taws xob ntawm 34CrMo4 roj lub tog raj kheej: tensile lub zog tom qab kev kho cua sov Ntau dua lossis sib npaug ntawm 980Mpa, yield zog Ntau dua los yog sib npaug rau 835Mpa, elongation tom qab tawg Ntau dua lossis sib npaug li 12%, -50 degree qis kub cuam tshuam lub zog Ntau dua lossis sib npaug li 27J.
34CrMo4 steel kav feem ntau xa hauv lub xeev dov lossis txias-daws. Lawv raug txiav thiab ua tiav rau hauv lub tog raj kheej roj lossis lub tog raj kheej steel thiab tom qab ntawd kho cua sov thiab tempered.
