Description
AISI 660 Round Bar
AISI 660 Round Bar is a precipitation-hardening austenitic stainless steel known for its impressive strength at high temperatures up to 700°C. Also sold under the names UNS S66286 and A286 Alloy. Alloy 660 gains its strength from a high degree of uniformity. It has an impressive yield strength minimum of 105,000 psi and is commonly used in high-temperature fastening and bolting materials.
AISI 660 chemical composition is that due to its high nickel content for stainless steel, it is often categorized as a nickel alloy, thus the A286 label.
AISI 660 is a high-carbon, high-chromium steel alloy that is part of the stainless steel family. It is typically used in applications requiring a combination of high hardness, strength, and wear resistance, especially at elevated temperatures.
AISI 660 is a high-performance steel used for applications that require superior wear resistance, strength, and corrosion resistance, especially in high-temperature environments.
AISI 660 (also known as UNS S66286 / A286) is a high-performance, iron-based superalloy that is known for its excellent strength, corrosion resistance, and oxidation resistance at elevated temperatures. It is commonly used in high-stress, high-temperature environments such as aerospace, power generation, and chemical processing.
