AISI 1045 \/ s45C muaj lub zog loj me me cov pa roj carbon hlau phaj rau cov tshuab seem

1. Cov ntsiab lus tshaj tawm thiab sib npaug

Tus qauv:

AISI 1045: American hlau thiab steel lub koom haum (AISS lub koom haum (AISI) qauv rau cov hlau, ib feem ntawm "10xx" series (dawb carbon hlau).

S45C: Japanese txoj kev lag luam (JIS G4051) sib npaug, siv dav hauv Asia rau kev siv Machinery thiab cov ntaub ntawv siv tsheb.

Kev sib faib: Nruab Nrab-Carbon Steel(tsis yog cov hlau me me, txawm hais tias lub sijhawm hauv qee cov ntsiab lus) nrog{{{{0}}. 42-0.50% cov ntsiab lus carbon, muab kev sib npaug ntawm lub zog, kev nruj me ntsis, thiab machinatability.

2. Tshuaj lom neeg sib xyaw (raug,%)

Lub ntsiab	AISI 1045 Neb	S45c ntau yam	Sau ntawv
Carbon (c)	0.42–0.50	0.43–0.51	Lub ntsiab tseem ceeb rau lub zog; siab dua c txhim kho hardness tab sis txo cov ductility.
Manganese (mn)	0.60–0.90	0.60–0.90	Txhim kho cov tawv tawv thiab lub zog tensile.
Phosphorus (p)	Tsawg dua los yog sib npaug rau 0. 040	Tsawg dua los yog sib npaug rau 0. 030	Tswj kom txo qis brittleness.
Sulphur (s)	Tsawg dua los yog sib npaug rau 0. 050	Tsawg dua li lossis sib npaug rau 0. 035	Qis dua s hauv s45c kom zoo dua ductility \/ Weldability.

3. Cov Khoom Siv Kho Tshuab

Ntiag tug	Raws li-dov (raug)	Tshav kub-kho (quenched & tempered)
Paib lub zog	Ntau dua los yog sib npaug rau 295 mpa (43 ksi)	355-510 mpa (52-74 ksi)
Lub zog tensile	570-700 MPA (83-102 KSI)	685-835 MPa (100-121 KSI)
Elongation (200 hli)	Ntau dua los yog sib npaug rau 16%	Ntau dua los yog sib npaug rau 13%
Hardness (HB)	170-210 Hb	200-250 HB (Tom qab Tempering)

 

 

 

 

 

 

Cov ntawv tseem ceeb:

 

Kev Kho Cua Sov: AISI 1045 \/ s45C feem ntauquenched thiab temperedtxhawm rau txhim kho lub zog thiab kev tawv nqaij rau qhov chaw tseem ceeb.

Kev muaj zog: Nruab nrab cuam tshuam tiv thaiv (Charpy V-NotC ~ 27 J nyob rau hauv chav sov) thaum ua kub kub kho.

4. Cov yam ntxwv tseem ceeb

Lub zog thiab kev sib npaug sib npaug:

Ntau dua cov pa roj carbon ntau dua li cov hlau me me (piv txwv li, AISI 1018) muab lub zog zoo dua, ua rau nws cov cim thauj khoom.

Txo cov pa roj carbon ntau dua cov hlau hluav taws xob siab (piv txwv li, 1095) kom ua kom zoo dua ductility thiab cuam tshuam tsis kam.

Luam ntawv:

Zoo heev testinity ntsuam (~ 60% ntawm AISI 1112 DAWB-machining hlau), zoo tagnrho rau kev tig, milling, thiab drilling.

Hwj txwv:

Moderate weldability; Preheating (100-200 degree) thiab tom qab weld kev kho cua sov (duab) kom pom zoo rau cov kab tuab kom tiv thaiv kev tawg.

Deg Hardening:

Yuav yog cov ntaub ntawv-tawv lossis induction-hardened rau kev coj tsis kam nyob rau hauv zog los yog shafts.
