Product Description

Name: Hot forging AISI4140 steel roller shaft bar

    Forging steel shaft bar is a type of mechanical component made by subjecting a solid billet of steel to a forging process. This process involves heating the metal to a malleable state, then shaping it under immense pressure using a die or a series of dies to form the desired shape. The forging method ensures the material's uniform grain strusture and enhanced mechanical properties.
   Forging steel shaft bars are commonly used in various industries due to their strength, durability, and resistance to fatigue.They are often preferred for applications that require high load-bearing capacity, such as in a machinery, automotive components, arespace, and industrial equipment. The forging process can result in improved tensile strength, hardness, and resisitance to deformation, making these shafts ideal for situations where reliability and longevity are crucial.
Advantages of forging steel shafts:
1. Forging eliminates the need for extensive post-forging treatments like heattreatment or machinig, which can lead to incomsistencies in the final product.
2. Forging process strengths the material by aligning the grain structure, resulting in greater tensile and compressive strength. 
3. Forged shafts have fewer micro-cracks, reducing the liklyhood of failure under cyclic loads.
4. The forging process allows for precise controlover the final shape and size of this shaft.
5. Forging can produce a smooth, clean surface without surface defects.

Forged steel shaft bars are commonly used in various of industries, such as forging equipment, power plant equipmnet, hydraulic equipment, steel mill equipment, petroleum machinery, etc. 
The production process as "EF + (LF) + (VD) + ESR" + forging and annealing(or normalizing) + heat treatment(quenching and tempering) + Maching + Packaging + Delivery.
Quality control: chemical analysis, optical spectrum instrument, Mechanical properties for tensile strength, yiels stress and elongation. Hardness testing, impact testing, coordiate measuring machine(CMM), metallographic analysis, magnetic flaw detector, Ultrasonic flaw detector.
