Yog C17200 nyob rau hauv lub xeev annealed mos los yog lub xeev hardened

1. Puas yog C17200 nyob rau hauv lub xeev annealed (mos) lossis lub xeev hardened?

C17200 beryllium tooj liab alloy yogtsis muaj qhov txwv rau qhov muag muag lossis tawv tawv-nws qhov kev siv tshuab yog nyob ntawm kev tshaj tawm - kev ua haujlwm (kev kho cua sov lossis kev ua haujlwm txias) siv thaum tsim khoom.

Annealed (Soft) Xeev: Qhov no yog lub xeev feem ntau ua rau C17200 thaum muab khoom tsis muaj qhov tshwj xeeb hardening. Nws undergoes annealing (cua sov rau ~ 780-820℃tom qab txias txias) los txo cov kev ntxhov siab sab hauv, ua rau cov qauv muag muag. Lub xeev no zoo tagnrho rau cov ntawv thov kev tsim, khoov, lossis machining (xws li, cov khoom siv hluav taws xob, cov khoom siv precision).

Lub Xeev Hardened: C17200 tuaj yeem hardened los ntawm ob txheej txheem tseem ceeb:

Ua haujlwm txias: Yas deformation (piv txwv li, dov, kos duab) ntawm chav tsev kub nce hardness thiab lub zog (piv txwv li, ib nrab- nyuaj, puv - tawv tempers).

Hnub nyoog Hardening (Precipitation Hardening): Ob - cov txheej txheem (kev daws teeb meem + kev laus ntawm ~ 315-345 degree) uas ua tiav qhov siab tshaj plaws hardness thiab hnav tsis kam. Qhov no feem ntau yog siv rau kev ua haujlwm siab (piv txwv li, springs, li qub, tooling).

2. Lub hardness ntawm C17200 yog dab tsi?

Lub hardness ntawm C17200 nws txawv heev nrog nws lub xeev ua thiab temper. Hauv qab no yog covkev lag luam- qauv hardness ranges(cov nplais feem ntau siv hauv kev sib txuas lus hlau:

Txheej Txheem/Temper	Hardness Range (HB)	Hardness Range (HRB)	Hardness Range (HRC)	Cov Lus Cim Tseem Ceeb rau Kev Lag Luam
Annealed (Mos, O Temper)	90-120 HB	60–80 IB	- (hloov heev rau HRC)	Default mov lub xeev; ductile rau fabrication
Txias-Ua haujlwm (Ib nrab-Hard, H12)	150-200 HB	85–95 IB	-	Balanced zog / ductility
Txias-Ua hauj lwm (Full-Hard, H18)	220-280 HB	98–105 IB	20-25 HRC	Siab zog, txwv formability
Hnub nyoog -Hardened (H1050/T6)	300-400 HB	- ( nyuaj heev rau HRB)	32-40 HRC	Qhov siab tshaj plaws hardness; siv rau hnav- qhov chaw tiv taus

3. Dab tsi yog cov khoom siv hauv Suav teb rau C17200?

Suav teb tus qauv sib npaug ntawm C17200 beryllium tooj liab alloy yogQBe 2(GB/T 5231-2012Copper thiab Copper Alloy Wrought Products -Cov Khoom Siv Tshuaj thiab Cov Khoom Siv).

Standard AlignmentGB / T 5231-2012 yog tus txheej txheem suav nrog rau cov tooj liab alloys, ncaj qha mus rau ASTM B194 / B194M (tus qauv US rau C17200).

Chemical Composition Match: Ob qho C17200 thiab QBe2 muaj cov khoom siv tshuaj zoo ib yam:

Beryllium (Be): 1.80-2.10%

Cobalt (CO): 0.20-0.50%

Copper (Cu): Qhov seem (Ntau dua lossis sib npaug li 97%)

Thaum sib txuas lus nrog Suav manufacturers lossis cov neeg siv khoom, siv "QBe2 (GB/T 5231)" raws li qhov sib npaug ntawm C17200. Qhov no ua kom cov khoom sib xws hauv cov lus hais, kev yuav khoom, thiab kev qhia tshwj xeeb.
