What is the difference between EN 1.7240 steel and nickel 600?
What is the difference between EN 1.7240 steel and nickel 600?
EN 1.7240 steel is a chromium-molybdenum alloy steel, while Nickel 600 (also known as Inconel 600) is a nickel-chromium alloy steel. The main difference between the two lies in their basic composition: EN 1.7240 is an iron-based alloy steel containing a large amount of chromium and molybdenum to improve its strength and hardness; while Nickel 600 is a nickel-based alloy, favored for its high-temperature strength, oxidation resistance, and corrosion resistance.
What is the equivalent material of Inconel 600 casting alloy?
Inconel 600, equivalent to UNS N06600, is a high-strength nickel-chromium alloy. It is known for its excellent corrosion resistance, strength, and superior performance even at extreme temperatures. This alloy contains not only nickel and chromium, but also iron and many other different elements.
EN 1.7240 steel is an alloy steel formulated specifically for initial forming into forged products. 1.7240 is the EN numerical designation for this material. 60CrMo3-2 is its EN chemical designation. Among EN forging alloy steels, EN 1.7240 steel has moderately high tensile strength and moderately low melting point.
Nickel 600 is a nickel alloy formulated specifically for initial forming into forged products. NA14 is the British Standard (BS) number for this material. N06600 is its United Nations Standard (UNS) number. Nickel alloy 600 is its commonly used industry name. Additionally, its French Association for Standardization (AFNOR) number is NC15Fe.
