17-4PH Stainless hlau kav

17-4PH Stainless hlau kav

Khoom Taw Qhia

Alloy 17-4PH stainless steel kav feem ntau yog siv rau qhov chaw uas yuav tsum tau corrosion kuj thiab siab zog nyob rau hauv chav tsev kub, los yog kub txog li 315 degree (599 degree F). Cov alloy tuaj yeem muaj hnub nyoog sib txawv ntawm qhov kub thiab txias kom ua tiav cov khoom sib txawv raws li qhov yuav tsum tau ua.

1. Tshuaj muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg ntawm 17-4PH feem ntau suav nrog:

· Carbon (C): Tsawg dua lossis sib npaug rau 0.07%

· Manganese (Mn): Tsawg dua lossis sib npaug rau 1.00%

· Silicon (Si): Tsawg dua lossis sib npaug rau 1.00%

· Chromium (Cr): 15.00~ 17.50%

· Nickel (Ni): 3.0~5.0%

· Phosphorus (P): Tsawg dua lossis sib npaug rau 0.04%

· Sulfur (S): Tsawg dua lossis sib npaug rau 0.03%

· Copper (Cu): 3.0~5.0%

· Niobium+tantalum (Nb+Ta): 0.15~{4}}.45%1

2. Mechanical zog
Tom qab kev kho cua sov, 17-4PH muaj cov khoom zoo heev:

· Tensile lub zog: nyob ntawm qhov sib txawv ntawm kev laus kub, nws tuaj yeem ncav cuag 1310 MPa txog 930 MPa1.

· Yield zog: Nyob ntawm qhov kub thiab txias, nws tuaj yeem ncav cuag 1180 MPa rau 725 MPa1.

· Elongation: Nyob ntawm qhov kub thiab txias, nws tuaj yeem ncav cuag 10% txog 16% 1.

· Sectional shrinkage: nyob ntawm qhov kub thiab txias, nws tuaj yeem ncav cuag 40% txog 50% 1.

· Hardness: Raws li cov kev kho cua sov sib txawv, qhov sib txawv hardness tuaj yeem ua tiav, xws li Tsawg dua lossis sib npaug ntawm 363HB thiab Tsawg dua lossis sib npaug rau 38HRC hauv cov khoom siv tshuaj, Ntau dua lossis sib npaug rau 375HB thiab ntau dua lossis sib npaug rau 40HRC Tom qab kev laus ntawm 480 degree.

3. Cov yam ntxwv ntawm kev kho cua sov
Kev kho cua sov ntawm 17-4PH suav nrog kev kho kom zoo thiab kho kev laus:

· Cov khoom siv kho mob: txias ceev ntawm 1020 ~ 1060 degree .

· Kev laus kev kho mob: Cov khoom siv sib txawv tuaj yeem ua tau raws li qhov sib txawv ntawm kev laus (480 degree, 550 degree, 580 degree, 620 degree).

4. Kev ua haujlwm thiab vuam kev ua haujlwm
17-4PH muaj cov khoom ua haujlwm zoo thiab tuaj yeem ua tiav los ntawm cov txheej txheem kev ua haujlwm zoo ib yam. Hom hlau no kuj muaj qhov zoo vuam zoo, tab sis nws yuav tsum tau them sai sai rau preheating thiab tom qab vuam thaum tshav kub kub kev kho mob thaum vuam kom tsis txhob muaj qhov tshwm sim ntawm cov kab nrib pleb.

5. Cov chaw thov
17-4PH yog siv dav hauv:

· Aerospace: siv los tsim cov iav tsaws, iav qhov chaw, aircraft accessories, thiab lwm yam.

· Kev lag luam tshuaj: siv los tsim cov khoom siv tshuaj tiv thaiv corrosion thiab cov khoom siv.

· Dej hiav txwv engineering: Vim nws zoo tiv thaiv dej hiav txwv corrosion, nws yog tsim rau offshore platforms thiab khoom siv.

· Nuclear kev lag luam: siv nyob rau hauv kev tsim khoom ntawm tej yam khoom rau nuclear reactors.

Great Plains Stainless stocks lub 17-4PH stainless hlau kav hnub nyoog hardened ntawm H1150 (620 degree ). Txawm li cas los xij, nyob ntawm cov neeg siv khoom xav tau, cov kav dej tuaj yeem muab nkag rau hauv cov tshuaj annealed lossis lwm lub hnub nyoog hardened kub raws li tau hais hauv cov lus hauv qab no.
