Description
We are professional Forging forged Steel Mechanical presses Crankshafts, Eccentric presses crank shafts, High Speed Press machine crankshafts, crank press crankshafts,stamping presses crankshafts from china
The maximum diameter of forging steel mechanical presses crankshafts that we could produce is up 2 meter
The maximum length of forging steel eccentric press crankshafts we could produce is up to 10 meter
The maximum weight of forging steel High Speed Press machine crankshafts is up to 20 tons
FOllowing is material grade that is normally used in forged steel mechanical presses crank shafts
Following the steel grade of Gas Compressor Crankshaft that we could do
AISI 1045, AISI 4140, AISI 4340,, 42CrMo4, 25CrMo4, 34CrNiMo6, 17CrNiMo6-4 34CrMo4, 30CrNiMo8, 36CrNiMo4, 40NiCrMo7, 41CrALMo7, 30NiCrMo12,18CrMos4, 18CrNiMo7-6, 17CrNiMo6,, St52-3, S355j2g3, 50CrMo4, 39NiCrMo3
We could do forged,normalized resp.quenched and tempered,inspected and certified,finished according drawing of mechanical presses crank shafts
ALl our mechanical press crankshafts is Free from blow holes,cracks or other material separations as well as from other defects and self-equilibrating stress which may affect the application.Segregation clusters as well as welding are not permitted.
ALl our finished forged eccentric presses crankshafts will have Inspection certificate 3.1 acc.EN 10204
The inspection Certificate shall include:
1. Chemical Composition.
2.Melting method
3. Tensile testing acc.DIN EN 10002-1 (Tensile strength Technical elastic limit =0,2%,Elongation,Throat
4. Beam Impact Test (average out.of 3 testings) acc.DIN EN 10045-1 by using ISO-V notch specimen
5. Hardness test according DIN EN 10003-1 (Brinell)o DIN EN 10109-1(Rockwell C)at three spots across the total length
6.Proof of the inner consistency (UItrasonic testing acc.EN10228-3 Class 3 C)
7. Information on heat treatments (tempering,stress relief annealing,normalizing)
8. Dimension inspection (Dimension record)
9.Proof of surface roughness Rz in the bearing zones
10.Proof that the entire finished product is free from cracks (Magnetic particle test acc.EN10228-1 class 4)
ldentification Of all our finished high speed press machine crankshafts : Finished Product as well as Inspection certificate:OrderNumber,Manufacturer Code,Number of melt and specimen, Material short cut,Borsig order code,identification by stamp
Each mechanical presses crank shaft separately conserved and separately packed in plywooden case
