Go With The Flow In processes such as open die forging and the production of seamless rolled rings, grain flow is important in that it beneficially affects the mechanical properties and the accompanying service life of the finished forged parts. Grain flow may be defined as the creation of a directional grain structure
Aim High In the final analysis, quality boils down to “what will do the job.” This applies to any size or shape or surface finish or hardness, etc. Which is why the end application of a part is of prime importance, and why it’s so necessary for the supplier to know the end
Selecting The Right Steel For The Job The United States has always been one of the world leaders in the oil and gas business, but with the serious advent of fracking a couple of decades ago, it became the world’s number one producer of crude oil and gas. Fracking, or hydraulic fracturing, is
A Closer Look At Heat Treating and Chemistry In Steel When a forging with around 0.8% carbon comes off the press and is cooled to ambient temperature, it has a microstructure of ferrite plus pearlite; over 0.8% carbon, one of pearlite plus cementite. Ferrite is effectively pure iron, pearlite is ferrite plus cementite. Under
Chemical symbol C, atomic weight 12, atomic number 6 We all know what carbon is, that it exists as charcoal, coal, coke, and after millions of years under extreme pressure, diamonds. But for the most part it’s a dirty, messy, shapeless mass that seems good for nothing apart from being burned or reducing
by Dell Williams Originally published on Manufacturing.net Machine shops often need open die forged parts for a variety of applications, including large, custom parts, small quantity runs or when high strength and durability are required. When this is the case, machine shops often contract with forgers for “as forged” parts and then perform finish
All Metals & Forge Group featured in Thermal Processing Magazine Understanding the end use of the parts we manufacture helps us produce the highest quality forged parts. Read all about it in Thermal Processing Magazine below.
One Alloy. Many Uses As we previously mentioned, the stainless steel that Harry Brearley discovered was what came to be known as type 420, or what we call a martensitic stainless steel. Or a hardenable stainless steel that may be hardened and tempered, as are normal carbon or alloy steels. There are also
Origins Stainless steel was first recognized as a commercial proposition in 1913, by Harry Brearley, a metallurgist in Sheffield, England, after he noticed that certain gun barrels containing around 13% chromium didn’t rust when they were left outside. What he’d discovered was a steel that approximates to what we know today as type
Stainless Steel In Wind Turbines by Royce Lowe In 2022, wind energy increased by some 265 TWh, or 14%, to reach over 2100 TWh. This represented the second highest growth among renewable power technologies, behind solar PV. But to make serious progress towards the Net Zero Emissions by 2050, which is looking
