· Another advantage of cast valves is that they can be much more easily produced in more complex designs than forged valves. Forged trunnion ball valves (for instance) are usually in 3 pieces, particularly the larges sizes to reduce costs as larger forgings are exponentially dearer. This means there is either an additional flanged connection that ...
Answer (1 of 2): Once upon a time, all crankshafts were forged steel. Ford introduced the use of ductile cast iron crankshafts. For heavy duty and high performance use, forged is preferable. For ordinary use, the adequate but economical cast ''cranks'' are a better deal.
· Cast is the process of pouring molten metal into a cast to give the desired shape. Forged is the process of pounding, either mechanically or manually, on a solid piece of metal to forge the shape. Players would often consider forged irons superior because of the perception, real or not, that the forging process gave the iron better feel.
The difference between cast, flow formed, and fully forged wheels is all in the manufacturing process – and the effect it has on the end result. Weight for weight from one style to another, fully forged wheels are by far the strongest at the lightest weight. They have greater load capability and resist cracking, denting and breaking, making ...

· Once heat treated, the forgings offer both superior tensil strength and improvements in elongation (essentially the amount of deflection before breakage). In terms of tensil strength, cast cranks start near 60,000 psi, but forgings can more than double this rating to (as high as) 125,000 psi. The elongation rating of factory cast cranks is an ...

Discussion Starter · #1 · Jan 3, 2015 (Edited) I was on another forum eek and a Ruger SR1911 thread that was generally very pro Ruger devolved into a cast/MIM vs forged general whizzing contest. It was closed with these words by the mod: "Those topics have been beat to death, brought back and beat to death again far too many times.
With forging, you have to have access to hit the metal. With casting, though, you have much more design freedom. Just compare a combination wrench …

· For example, an F92 Class 2500 valve at 1112°F (600°C) delivers a special class rating of 223.4 bar compared with 203.1 bar for F91. At 1067°F (575°C), the ratings are the same for both materials (F91 and F92). However, at 1157°F (625°C), the difference is 190.6 bar for F92 compared with 152.1 for F91. Although chemical composition is an ...
Forged valves do tend to be better for high temperature and high pressure applications. These types of valves are less prone to thermal fatigue because the walls are thinner compared to cast alternatives. Also, forged options have a higher mass, making them mechanically stronger. However, there are a few reasons why a forged ball valve may not ...

Answer (1 of 3): Neither is better. Both processes have specific characteristics and you choose the one which is most appropriate for a given application. Often forged parts end up having better mechanical properties than cast ones but this is not an absolute and
· I Found a cool read about the differences in pistons. Thought I would Share. The Author is Mike Nixon. Which is better, the cast piston or the forged piston? This argument doesn''t come up as often as it used to. During the 1970s it was a frequently debated topic: The answer used to be simple...
· Other benefits of cast valves include the fact that they are cost effective due to the fact of reduced labour and time compared to forged valves. But on larger valve bodies they are often more expensive due to the amount of welding and changes needed to try and achieve the same level of quality. There are number of different types of casting ...
· Don''t get me wrong, i''ve had several cast SA receivers over the years, as well as other brands. I''ve never had any issues related to them. I also don''t put that many rounds through my M1A. The trend now though seems to be towards forgings again for this part
· Forged irons are famous for being great-feeling golf clubs. They are made with softer steel that usually has more carbon in order to make them more workable, keeping the grain of the steel packed in tight. This is what gives forged irons that signature feel and feedback golfers who love them often cite as to why they prefer this construction.
The choice of cast or forged for small parts usually comes down to the preference of the manufacturer. A shape like this is relatively easy to forge from round stock, and there are other advantages to forging such as absolutely uniform material with no bubbles, flaws, or slag inclusions. Better quality hammer heads are usually forged.
· In casting, the end product has a low tensile strength as the material is poured into a cavity which lets the material take its shape. Forging, on the other hand, produces high tensile products as they process a definite grain …
· Image: Eurico Zimbres. Steel casting involves pouring molten steel into a mold and allowing it to harden as it cools. Casting is amenable to the manufacture of complex shapes and particularly large parts. However, cast parts end up with a random crystalline microstructure that makes them potentially weaker than forgings.

Of course, that hasn''t ever stopped the gunshop commandos or Errornet experts who''ve often made the claim that they have. No flipping kidding.
Answer: A forged crankshaft is always better than a billet crank. The cost of forging dies prohibits low volume production. Billet crankshaft has discontinuous grain structure which is weaker and more likely to crack than the smooth grain flow in a billet crank.
All in all, casting tends to be the less expensive, more versatile option, however; forging offers superior strength and wear resistance. The question of which is better depends on the top priorities for your project. If low cost, exotic alloys, …
This lack of "grain" is what makes a good flint chip with controlability in all directions. Chips in a cast steel anvil are very sinilar to presure flakes in flint. Good forged or rolled steel is more resistant to chipping in this one area. Or at least the chips do not run as far. However, forged anvils do not necessarily have the proper grain ...
· Investment casting in the early 1980''s was done with VERY hard metals (lots of 17-4 stainless) that sounded harsh and produced bone-jarring vibration on off-center impact, but the better cast designs still captured the attention of the golfer-consumer, as they were indeed superior performers to forged blades.
With forging, you have to have access to hit the metal. With casting, though, you have much more design freedom. Just compare a combination wrench (forged) to an exhaust manifold (cast). Casting is a great solution for parts with internal …
· Forged parts have a 37% higher fatigue strength resulting in a factor of six longer fatigue lives. This means that a forged shackle is going to last longer. Cast steel only has 66% of the yield strength of forged steel. Yield …
· The internet is full of discussions over which parts are better. cast or forged, it doesn''t matter if you''re talking about gun parts or car parts, it seems that the overwhelming consensus is forged parts are better. simply put, cast parts are weaker because they have all these voids in them they have no grain structure. there''s no ...

· Posted by Marc M. on 20th Dec 2018. The two main processes used in shear manufacturing are cast and forged. In the process of making a cast shear, liquid metal is poured into a mold and then allowed to harden. Forged shears are made from molten steel that''s poured into a die and then hammered to ensure that the scissor is perfectly formed, both ...
The advantages of forging include: Generally tougher than alternatives. Will handle impact better than castings. The nature of forging excludes the occurence of porosity, shrinkage, cavities and cold pour issues. The tight grain structure of forgings making it mechanically strong. There is less need for expensive alloys to attain high strength ...
