What is en HARDO X400 equivalent astm material
En HARDO X400 is a precipitation hardening stainless steel with a martensitic structure. It is a high-strength material that offers good corrosion resistance, toughness and formability. It is mainly used in components such as turbine blades and aircraft parts.
En HARDO X400 and Alloy A286 both belong to the series of precipitation hardening stainless steel alloys. Alloy A286 is a ferrous-based alloy with chromium, nickel and molybdenum. It is a versatile material and offers excellent strength, good creep resistance and good strength in temperatures up to 1200 degree Fahrenheit (650 degrees Celsius). It also provides good corrosion resistance and high fatigue strength in most environments.
The equivalent ASTM material for En HARDO X400 is ASTM A638 Grade 660. ASTM A638 Grade 660 is an austenitic iron-based alloy and offers higher corrosion resistance than most precipitation hardening steels, while maintaining high strength and hardness. It is typically used in applications where high strength and corrosion resistance are needed, such as fittings, flanges, pipes, tubes, electric motors and aerospace components.
En HARDO X400 and ASTM A638 Grade 660 are both versatile materials that offer high-strength and good corrosion resistance. Their wide range of applications makes them ideal for turbine blades, aircraft parts and other components where strength, toughness and formability are required. While En HARDO X400 offers good creep resistance and superior high-temperature strength, ASTM A638 Grade 660 offers superior corrosion resistance in most environments.
