42CrMo Blower Shaft Heat Treatment Stainless Steel Forging Transmission Coupling Shaft
42CrMo 45 Blower shaft Heat Treatment stainless Steel Forging
Products:
Used for centrifugal, axial and mixed-flow
42CrMo steel belongs to ultra-high strength steel, which has high strength and toughness, good hardenability, no obvious tempering brittleness, high fatigue limit and multiple impact resistance ability after tempering and tempering treatment, and good impact toughness at low temperature.42CrMo steel is suitable for large and medium sized plastic molds which require certain strength and toughness.

Process
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
Attention
- To control the forging temperature, do not coarse grain;
- To control the tempering process, to ensure that the core of the tempering and tempering
- The surface of the medium frequency hardening hardening layer depth control;
- Avoid surface micro-cracks.
Advantage
- High-precision dimensional tolerance;
- Excellent mechanical properties;
- Produce different dimension based on customer’s requirements;
- Advanced manufacture equipments and inspection devices;
- Excellent technical personality;
- Control the production procedure strictly;
- Pay attention on the package protection;
- Quality full service.
