7.42crmoSteel Application
42crmo steel finds many applications as forgings for the aerospace,oil and gas,automotive, agricultural and defense industries etc.
Typical applications for 42crmo steel uses include:forged gears,spindles,fixtures,jigs,collars,Axles,conveyor parts,crow bars,logging parts,shafts,sprockets,studs,pinions,pump shafts, rams, and ring gears etc
8.Quality control:
1. Melting Process: EAF/BOF+LF+VD resulting in ingots
2. Both ends cut by saw
3. Ratio of forging:minimum 3:1
4. Grain size of final product: according to ASTM E112 more than 5,preferred more than 8
5. Ultrasonic test: As per SEP1921 Class C/c or D/d
9.Heat treatment of 42crmo Steel
Quenched and Tempered (+QT) of EN19 Steel
1. Heat 42crmo steel slowly to 840-875°C;
2. Soak at this temperature then quench in oil;
3. Temper as soon as 42crmo reach room temperature (20°C);
4. Heat uniformly to the suitable temperature of 560°C;
5. Withdraw the material from the furnace and cool in the air.
Annealing of 42crmo Alloy Steel
1. Heat the 42crmoslowly to 800-850°C and allow enough time.
2. Cool slowly in the furnace to 480°C followed by air cooling
10.MOQ: one piece per size/grade
11.Payment term: FOB CIF CFR EXW and so on
12.Delivery time : 7 to 30 days after deposit received.
