Heavy Duty Rough Machined 70Cr3MoV Steel Forged Cylinder
9Cr2Mo 70Cr3MoV 410 420 2Cr13 Forged Cylinder , Forged Roller Shell Rough Machined
Steel forging is one of the oldest manufacturing methods in the steel industry, and involves compressive forces for shaping metals. However, there are some challenges in finding steel forged materials. Some of these challenges are long lead-time, high prices, sizes are not within forging companies’ specs, low quality materials, high maintenance costs and your specific shape is not supported by the manufacturer. We have the best solution for all the challenges within steel forging industry.

Process procedure:
Forging process flow quality control:
- Raw material steel ingot into warehouse(test the chemical content)
- Cutting→ Heating(Furnace temperture test)
- Heat treatment after forging(Furnace temperture test) Discharge the furnace(blank inspection)
- Machining→ Inspection(UT,MT,Visal diamention, hardness)
- QT→ Inspection(UT, mechanical properties, hardness, grain size)
- Finish machining→ Inspection (dimension)
- Packing and Marking(steel stamp, mark)→ Storage Shipment
