five.AISI 4140Steel Application
AISI 4140 steel finds numerous purposes as forgings for the aerospace,oil and gas,automotive, agricultural and defense EPTT and many others.
Common purposes for AISI 4140 steel uses incEPTT:solid EPTs,spindles,fixtures,jigs,collars,Axles,conveyor areas,crow bars,logging areas,shafts,sprockets,studs,pinions,pump shafts, rams, and ring EPTs and so forth
6.EPTT control:
one. Melting Process: EAF/BOF EPTT VD resulting in ingots
2. Each ends lower by noticed
3. Ratio of forging:bare minimum 3:one
four. Grain measurement of last item: according to ASTM E112 far more than five,chosen much more than eight
5. EPT check: As for every SEPT1921 Course C/c or D/d
7.Heat treatment method of AISI 4140 Steel
Quenched and Tempered ( QT) of EN19 Metal
one. Warmth EN19 metal gradually to 840-875 degC
2. Soak at this temperature then quench in oil
3. Temper as quickly as EN19 reach room temperature (20 degC)
4. Heat uniformly to the ideal temperature of 560 degC
5. Withdraw the content from the furnace and amazing in the air.
Annealing of EN19 Alloy Steel
1. Heat the EN19 slowly and gradually to 800-850 degC and enable adequate time.
two. Cool gradually in the furnace to 480 degC adopted by air cooling
eight.MOQ: one particular piece for every dimension/quality
nine.Payment time period: FOB CIF CFR EXW and so on
ten.Delivery time : 7 to thirty daEPTTafter deposit EPTd.
