60si2mna Alloy caij nplooj ntoos hlav hlau hlau

Cov cwj pwm thiab cov ntim ntawm daim ntawv thov:

Yog dav siv hauv Si Mn caij nplooj ntoos hlav steel, lub zog, elasticity thiab hardenability, me ntsis siab tshaj 55Si2Mn. Haum rau cov tsheb nqaj hlau, tsheb thiab tsheb laij teb tsim tau ib qho kev thauj khoom loj los yog lub caij nplooj ntoos hlav tiaj tiaj hlau nyob rau hauv lub caij nplooj ntoos hlav, hauv qab 30 hli yog tsim rau kev zus ntawm qhov kub ntawm 250 DEG C nonrefractory caij nplooj ntoos hlav corrosion nruab nrab thiab hauv qab hloov thiab hom loj nyob rau hauv kev nyuaj siab siab qhov tseem ceeb ntawm kev ua hauj lwm yob hlav.

Tshuaj Muaj Yug Tshuaj:

C: 0.56 mus rau 0.64

Si: 1.60 mus 2

Mn: 0.60 mus 0.90

S: = 0.030

P: = 0.030

Cr: = 0.35

Ni: = 0.35

Mechanical zog:

Qhov kawg ntawm lub zog ntawm B (MPa): 1568 (160)

Tawm kev muaj zog s (MPa): 1372 (140)

10 elongation (%): 5

Ntu ntsws (%): 20 PSI

Qhov nyuaj yog tsawg tshaj 321HB;

Specification thiab metallographic qauv ntawm kev kho cua sov:

Kev qhia txog kev kho cua kub: siv quenching ntawm 870 + 20 C, roj txias; tempering ntawm 440 C + 50 C (kev xav tau tshwj xeeb, + 30).
