Carpenter+Technology

**From Wikipedia: **
Carpenter Technology Corporation is a globally recognized developer, manufacturer and distributor of cast wrought and powder metallurgy specialty alloys/metals including superalloys, ultra-high strength steels, and stainless steel, as well as titanium alloys in a range of product forms.

Headquartered in Reading, Pennsylvania, Carpenter Technology maintains manufacturing and distribution operations throughout the United States, Mexico, Europe and Asia. Its most recent facility is a service center in China. In addition to the specialty alloys operation based in Reading, Carpenter acquired Dynamet Incorporated, Washington, Pa., a titanium alloy producer, and placed its tool steel and powder metallurgy business in the Carpenter Powder Products unit during the 1990s.

Beginnings
The company was founded by James H. Carpenter on June 1, 1889 as the Carpenter Steel Company. He envisioned methods to improve the process of steel manufacturing. In 1896, James Carpenter received the company's first patent for an improved air-hardened steel. In 1937 the company went public and began trading on the New York Stock Exchange.

Markets
During the early 20th century, Carpenter's "special" steels were used in Wright Brothers' heavier-than-air “aeroplanes,” and today Carpenter supplies specialty materials that have been used in jet engine blades, electronics, landing gear, and titanium alloy fasteners, among other uses. Also around this time, Carpenter began supplying steels to the makers of “motor cars” for valves, connecting rods, axles, steering knuckles, etc. Carpenter’s experience in these early markets led to materials advances in the energy, medical, industrial and consumer products industries in the coming decades.

Materials Experience
By the 1920s, Carpenter devoted research to a new realm of specialty metals: stainless steels. Carpenter metallurgists pioneered improvements and in 1928, announced the world’s first free-machining, straight-chrome stainless, Type 416 (still in use today). Other improvements and alloy development followed, culminating in an improved-machinability family of machining bar, Project 70+ stainless, in 2002. In high-strength alloys, Carpenter received a patent in 1992 for super-strong AerMet® 100 alloy, first used for the landing gear on aircraft-carrier-based jet fighters. AerMet 100 was named one of the top material advances of the decade by the National Association for Science, Technology and Society More recently, Carpenter developed the Carpenter CTS family of 14 alloys to assist knife blade designers in alloy selection. In 2009 Carpenter began supplying its cobalt-based BioBlu 27 alloy into the jewelry industry.
