This article continues FORGE’s series on forging
materials. The first installment on nonferrous forging materials discusses
aluminum alloys that are used in forged components. A general description of
aluminum alloys is followed by details of their chemistry and microstructure.
The rolling and thermal treatment of forged
rings sometimes leaves residual stresses that cause dimensional distortion.
Corrective measures in industry are often based on trial-and-error techniques.
Ongoing research seeks to base corrective actions on the laws of physics.
Like all steels,
microalloyed steels are iron-based metal alloys. Normally, they are plain
carbon or low-alloy steel with small additions of one of
three special elements. These steels were developed in the 1960s and used for
plate and pipeline applications. It was not until the 1980s, however, that
forgers began to produce microalloyed steel components in significant
all steels, stainless steels are iron-based alloys. They are considered a
special class of steels because of their high alloy content and their special
properties as compared to plain-carbon and low-alloy steels.
West Penn Testing, a Pennsylvania-based independent testing laboratory, has expanded its capacity and personnel to accommodate anticipated growth in commercial aircraft demand through the coming decade. The immersion ultrasonic testing process it performs is vital to the quality verification of flight-critical components.
The steel service-center industry is a valuable resource to the forging community. Those who supply steel to forgers suggest that the need for steel consumers to incorporate a steel service center into their supply management strategy has never been greater.
This Wisconsin forge, having positioned itself to endure a depressed economy, now sees that economy starting to recover. As the economy improves, Green Bay Drop Forge faithfully serves existing customers while aggressively pursuing new markets and applications.
