Comparison of EN 1.1151 steel and nickel 600 alloy
EN 1.1151 is a non-alloy carbon steel, while Nickel Alloy 600 is a high-performance nickel-chromium alloy. Their main difference lies in their composition: steel is primarily composed of iron, while Alloy 600 is primarily composed of nickel, and also contains chromium, iron, and other elements. This gives Nickel Alloy 600 greater corrosion resistance, especially in acidic environments, and makes it more suitable for high-temperature applications (up to 2000°F or 1095°C), while EN 1.1151 is a more common and less expensive general-purpose steel.
Are Nickel Alloy 600 and Inconel 600 the same alloy?
Nickel Alloy 600, also sold under the brand name Inconel 600, is a unique nickel-chromium alloy known for its oxidation resistance at high temperatures. It has a wide range of applications, suitable for high-temperature applications from low temperatures up to 2000°F (1093°C).
What is EN 1.1151 steel?
EN 1.1151 steel, also known as C22E, is a high-quality carbon structural steel conforming to the German DIN standard system. Its core characteristics include low carbon content (0.17%-0.24%), good surface hardening ability, and balanced strength and toughness, classifying it as a surface-hardening steel. This steel is often categorized as a quenched and tempered carbon structural steel. The chemical composition and mechanical properties of 1.1151 steel make it suitable for high-load components in machining, automotive manufacturing, and aerospace industries, such as gears, shafts, machine tool parts, automotive handbrake shoes, and bearings-heavy equipment components.
What is Nickel 600?
Nickel Alloy 600, also marketed under the brand name Inconel 600, is a unique nickel-chromium alloy renowned for its oxidation resistance at high temperatures. It has a wide range of applications, from low-temperature applications to high-temperature applications up to 2000°F (1093°C).
