5.4140 Steel Software
AISI 4140 metal finds a lot of apps as forgings for the aerospace,oil and fuel,automotive, agricultural and defense EPTT and so on.
Typical apps for 4140 metal makes use of incEPTT:forged EPTs,spindles,fixtures,jigs,collars,Axles,conveyor components,crow bars,logging parts,shafts,sprockets,studs,pinions,pump shafts, rams, and ring EPTs and so on
6.EPTT manage:
1. Melting Method: EAF/BOF EPTT VD ensuing in ingots
two. Each finishes cut by observed
3. Ratio of forging:least 3:1
4. Grain measurement of final solution: in accordance to ASTM E112 far more than 5,preferred a lot more than 8
5. EPT check: As for every SEPT1921 Class C/c or D/d
7.Heat remedy of 4140 Steel
Quenched and Tempered ( QT) of SAE 4140 Steel
1. Heat 4140 metal gradually to 840-875 degC
two. Soak at this temperature then quench in oil
3. Temper as quickly as AISI 4140 achieve space temperature (20 degC)
four. Warmth uniformly to the ideal temperature of 560 degC
five. Withdraw the content from the furnace and awesome in the air.
Annealing of AISI 4140 Alloy Metal
one. Warmth the SAE 4140 gradually to 800-850 degC and allow adequate time.
two. Amazing slowly in the furnace to 480 degC followed by air cooling
eight.MOQ: one particular piece for every measurement/grade
