Our Milestones

1907 Elwood Haynes receives a patent for an alloy he created. It is used for cutlery, dental instruments, automobile spark plugs, and other applications. He later named the metal STELLITE®.


1912 The United States Patent Office informs Haynes that he will be awarded two patents for his more advanced version of the STELLITE® alloys.

 Haynes employees



Elwood Haynes forms Haynes Stellite Works on Union Street in Kokomo, Indiana. The four employees begin producing his STELLITE® alloy for use in machine tools, dental equipment, surgical scalpels, and cutlery.

Haynes Stellite
Elwood Haynes and two local businessmen, Richard Ruddell and James C. Patten, incorporate the business as Haynes Stellite Company.

Haynes building1916 Lindsay Street property is acquired, expanding the business under the leadership of James Patten, the plant manager.

1918 Henry M. Leland, inventor of Cadillac and Lincoln automobiles, writes to Haynes highlighting the importance of the STELLITE® alloy to the war effort. He states, “We have found that this Stellite is very superior to the high-speed steel or anything else we have found.”

Union Carbide
Union Carbide purchases the Company.

1921 A patent is granted for a nickel-molybdenum alloy composition range, which allows the development of many proprietary alloys, including HASTELLOY® B alloy.

1922 HASTELLOY® trade name is invented. The name was created by taking letters from HAYNES STELLITE ALLOY = HASTELLOY®.

The hard-facing process is invented. This process involves welding a surface layer of STELLITE® alloys over parts of tools and machinery that are subject to wear and abrasion.

Spirit of St Louis

1927 Charles Lindberg’s aircraft, “Spirit of St. Louis,” crosses the Atlantic Ocean with STELLITE® hard-surfaced engine valves.

Casting foundry

1929 A new casting foundry is built to manufacture products for the growing chemical processing, petrochemical, and pharmaceutical industries that use the newly introduced HASTELLOY® alloys.

1930 The oil well drilling industry is one of the first applications for hard-facing with STELLITE® alloys. Oil field drilling would become a growing business to help us financially throughout the years of the Great Depression.

1931 HASTELLOY® C alloy, the first of the entire family of C alloys, is introduced for use in chemical plants, as well as aircraft engine components.

Radial engine

1936 The first unit of the Douglas DC-3 aircraft is delivered. STELLITE® 21 alloy is used to prevent exhaust valve seat wear problems in the Pratt & Whitney R-1830 “Twin Wasp” radial engines. Some of these planes are still flying today.

Women employees1937 The precision casting process is used to make parts, such as dental restorations and surgical bone pins. This process, also known as the “lost wax” or investment casting process, would lead to what might be considered the most important period of growth for us.

Amelia Earhart’s Lockheed Electra 10E is equipped with Pratt & Whitney engines using STELLITE® hard-faced engine valves.

1941 The United States enters World War II. STELLITE® alloys are combined with the precision casting process to create turbine blades or “buckets” that can withstand the high temperatures and stresses encountered in an aircraft engine supercharger. This product is crucial to the military and allows Allied bombers to fly above enemy anti-aircraft fire. Over 25 million buckets are produced during the war, which is 70 percent of all buckets used.

female worker

1943 “Rosie the Riveter,” in Kokomo, is producing turbo supercharger blades for the war effort. About half of the workforce, which peaked at about 2,000 employees, are women.

1945 One hundred acres of land south of the main plant are purchased and become the Defenbaugh Street Operations, producing wrought alloys. This is a critical turning point because wrought products would eventually constitute the whole business of Haynes International.

R-1 building

1948 Defenbaugh Street Operations’ R-1 building is constructed. It houses a melting furnace, a steam hammer forge, a three-high mill for hot rolling plate and a two-high mill for hot rolling sheet, a 24-inch bar mill, and a 10-inch bar mill. Most of this equipment is still in operation today.

This allows the Pratt & Whitney F100 engine, which powers the McDonnell Douglas F15 attack aircraft, to achieve unmatched speed and climbing records.

Electro slag remelting (ESR) capability for wrought alloys is introduced. This results in considerable yield improvements, enhanced alloy hot workability, and overall quality improvements.

1969 When Neil Armstrong, Buzz Aldrin, and Michael Collins go to the Moon on Apollo 11, it took nearly 14 tons of products made from our alloys in their Saturn V rocket to get them there. F-1 rocket engines employ HAYNES® 713C alloy turbine blades, HASTELLOY® C alloy nozzle skirt extensions and heat exchangers, an R-41 alloy turbopump manifold, and HASTELLOY® W alloy weldments.


1970 Cabot Corporation purchases the Company. As a measure of respect for tradition, Cabot management continues the “Stellite Division.”The argon-oxygen decarburization (AOD) process is added and dramatically expands the applications for the Stellite Division’s corrosion-resistant products in the chemical process industry.

Our history spans more than a century of products, processes, and most of all, people. Also captured is the introduction of many well-known nickel- and cobalt-base alloys that have been used worldwide in the most demanding environments and critical applications for aerospace, power generation, chemical processing, pharmaceuticals, and other areas.

Our research and development commitment is also unique in today’s highly competitive environment. Often research and development can take several years to go from an idea to a viable alloy product. The nickel and cobalt metallurgy field has been thoroughly researched over the last 100 years, but R&D remains an important part of our business and new alloys will continue to be invented.

Our products are used throughout the world in the most demanding environments and critical applications, just as they were at the beginning of the 20th century. Our products are used in parts for almost every commercial airplane flying today, as well as in military aircraft for the United States and its allies. Alloys invented and produced throughout our history flew on every one of the Apollo and space shuttle flights and are found in most rocket parts used in satellite launches today, as well as the latest “Curiosity” Mission to Mars.

We look forward to our future and continuing our Tradition of Innovation.
