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
Quality Is Priority #1 by Royce Lowe In the world of steel manufacturing, precision and quality are paramount. From mining equipment to food processing machines, forged steel parts serve as the backbone of modern infrastructure and industry. However, ensuring that this vital material meets rigorous standards requires more than just raw materials and
The Origins Of Manufacturing Quality Not that long after the end of WWII, an American named W. Edwards Deming tried to talk his fellow countrymen into putting quality into their products. This was at a time when the term quality control meant a bunch of inspectors sifting through finished products, large and small,
