Nickel & SuperAlloys (Ni & Co)

Prompted by advancements made in gas turbine engine technology, Superalloys (both Nickel and Cobalt) have been in use since the 1930’s. Demonstrating high strength at high operating temperatures, Superalloys are ideal for use in not only aerospace, transportation and power generation but also in manned and non-manned spacecraft programs as well. While superalloys offer many advantages to engineers and designers, maintaining tight controls on grain size, toughness, creep and other mechanical properties is critical. This can be made more challenging by most superalloys strain rate dependency; in that they are softer when forged slowly and strengthen when forging speeds increase. Utilizing open framed presses with CNC controlled variable forging speed controls, Mattco utilized proprietary forging techniques that minimize cracking, increase yield and ensure the highest quality forged metal components. 

Titanium (Ti)

Titanium is extremely corrosion resistant and offers the highest strength-to-weight ratio of any metal, making it a popular choice for aerospace, military and industrial applications. Titanium is a shape memory alloy, and its affinity for absorbing anatomic hydrogen presents challenges when forging titanium. Mattco has developed a number of proprietary processes to eliminate these factors, allowing us to offer dimensionally stable, low hydrogen titanium forgings. 

Aluminum (Al)

Aluminum has a remarkably low density and is extremely corrosion resistant, making it a mainstay for structural components in many industries including aerospace, defense and transportation. Although aluminum’s ductility makes it easy to forge, it also makes aluminum susceptible to residual stresses during the heat treating process which can lead to movement of the part during subsequent machining processes. Since its founding, Mattco has worked diligently to develop strict control over the manufacturing and thermal processing of aluminum that allow us to optimize mechanical properties and minimize residual stresses in our forged aluminum products. 

Stainless Steel

Stainless Steel is used in a variety of industrial applications where moderate strength and enhanced corrosion resistance is required. By varying the chromium content (usually between 13% and 26%), a wide range of corrosion resistance can be achieved. As operating environments become more demanding and the ability of key components to resist corrosion degradation, many industries are turning to Stainless Steel. The wide range of stainless steel grades means a thorough understanding of its properties is important throughout the forging process. While more standard grade stainless steels forge easily and are less susceptible to residual stresses than other alloys, the more complex stainless steels require far more sophisticated forging techniques to optimize corrosion resistance and mechanical properties. Mattco Forge Inc has decades of experience forging all grades and types of stainless steel. 

Alloy + Carbon Steel

Iron alloyed with carbon and other elements such as chromium, nickel and molybdenum, form the basis for the majority of steel products used today. While iron has been used for millennia in countless applications, the addition of carbon and other alloying elements in recent times has increased the strength of the metal by up to 1000 times, revolutionizing its uses. Further advancements in the heat treating and forging processes enable further refinement to the mechanical properties of steel, usually ductility, hardness, yield strength, or impact resistance. Mattco Forge Inc. has decades of experience with all types of carbon and alloy steels, forging seamless rolled rings and other shapes for a wide range of industries and applications.
