The metalworking industries, and many others, couldn’t operate without tool steels. This branch of alloy steels serves to cut and grind and bend and deep draw metals and materials from one form or shape to another. They are indispensable. The basic requirements for a tool steel are hardness, thus wear resistance, fatigue strength, toughness,
Aluminum is light, can be alloyed, forged, and heat treated to increase its strength. It may be hot and cold formed, machined, and welded. Its density is about one third that of steel. AMFG has solid experience in the fabrication and use of aluminum and its alloys. Extraction of the metal from its ore
Lightweight and Strong - At A Cost Titanium is an expensive metal. But it’s light, strong at sub-zero, ambient and elevated temperatures, tough and ductile, corrosion resistant and relatively easy to form and machine, although it is generally twice as costly to machine as aluminum. It has enabled us to fly, and at
Many Grades. Many Applications. There is a classification of steels, alloy steels, AISI/SAE, that covers some one hundred grades, from a nominal 0.10% carbon, through to a nominal 1.0% carbon. The grades are used in myriad applications in the aerospace, agricultural, automotive, defense, and oil and gas industries. They are also used to
Understanding Heat Treatment Annealing reduces the hardness, improves machinability, facilitates cold forming, produces a desired microstructure, and alters mechanical properties. Annealing normally means full annealing, which involves heating the steel - which has a structure of ferrite plus carbide - to its austenitizing temperature, leaving it at that temperature (soaking) for a predetermined
What are the primary and secondary melting processes that ensure the soundest, cleanest, alloy ingots for forging? Most metals and alloys, particularly steel, are air melted, meaning no controlled atmosphere is involved. Air melting economically gives alloys those properties needed for less-demanding applications, and many specialty alloys are still air melted today. The
Carbon's Role In The Treatment Of Steel Carbon’s role in the treatment and properties of steel is best explained through a steel’s fabrication and subsequent heat treatment. A plain carbon steel, up to 0.8% carbon, that has been forged and taken directly from the machine, will show a structure of ferrite (iron) and
The Workhorse Of The Stainless Family by Royce Lowe The stainless 300 series might be described as the workhorses of the greater family of stainless steels. As a group, they show better corrosion resistance, toughness, high-temperature strength, and low-temperature properties. They are based on what was called the 18/8 steel, or type 302,
The Importance of Carbon In Steel by Royce Low Carbon is very important in the context of hardness and strength. But in the broader context of steel metallurgy, hardenability is, overall, just as important, if not more so. This property may be defined, simply, as the ability of a steel to harden to
Go With The Flow by Royce Lowe 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
