Why use steel forging as your metal forming process?

steel forgingThere are a lots of metal forming process for a metal designed part,such as casting,forging,stamping,welding fabrication,ect.Each process has its own characteristics.Sometimes we can use casting or forging either.But by comparison,purchasers will prefer steel forging as the metal forming process.Below we explain in detail why use steel forging as your metal forming process?What are the advantages?

Consistency

The consistency of steel material from one forging to the next,and between separate quantities of forgings is extremely high.Steel forged parts are made through a controlled sequence of production steps rather than random flow of material into the desired shape.Uniformity of composition and structure piece-to-piece,lot-to-lot,assure reproducible response to heat treatment,minimum variation in machinability,and consistent property levels of finished parts. 

Dimensional characteristics are remarkably stable.Successive steel forgings are produced from the same die impression,and because die impressions exert control over all contours of the steel forged part,the possibility of transfer distortion is eliminated.

Mechanical Properties

The structural reliability achieved in a steel forging is unequalled compare to other metal forming processes.No internal gas pockets or voids are produced inside of steel forgings that could cause unexpected failure under stress or impact hit by hot die forging press.The structural reliability of steel forgings means less inspection requirements,uniform response to heat treatment,and consistent machinability.These qualities will be helpful for faster production rates and lower costs.

Directional strength is a direct result of the steel forging process.In the steel forging process,controlled deformation results in improved mechanical properties of the material.Forging produces directional alignment (or "grain flow") for important directional properties in strength,ductility,and resistance to impact and fatigue.These properties are deliberately oriented in directions requiring maximum strength.

Properly developed grain flow in steel forgings follows the outline of the component.In contrast,bar stock and plate have unidirectional grain flow;any changes in contour will cut flow lines.As a result,the material is more susceptible to fatigue stress.To the designer,the structural integrity of steel forgings means safety factors based on material that will respond predictably to its environment without costly special processing to correct for internal defects. 

The resulting higher strength-to-weight ratio can be used to reduce section thickness in part designs without jeopardizing performance characteristics of safety.Weight reduction,even in parts produced from less expensive materials,can amount to a considerable cost savings over the life of a product run.

Economics

Economically,steel forged products are attractive because of their inherent superior reliability,improved tolerance capabilities,and the higher efficiency with which steel forgings can be machined and further processed by automated methods.So there is a large market for steel forgings  manufacturer to export their products and it seems quite important to be a good steel forgings manufacturer.

The near absence of internal discontinuities or surface inclusions in steel forgings provides a dependable machining base for metal-cutting processes such as turning,milling,drilling,boring,broaching,and shear spinning;and shaping processes such as electrochemical machining,chemical milling,electrical-discharge machining,and plasma jet techniques.

Steel forged parts are readily fabricated by assembling processes such as welding,bolting,or riveting.The selection of a steel forging can often eliminate the need for assemblies.In many cases,steel forgings are ready for use without surface conditioning or machining.The forged surface is suited to plating,polishing,painting,or treatment with decorative or protective coatings.
