Frequently Asked Questions about Hastelloy X Powder

Here are answers to some common questions about Hastelloy X powder:

Q: What is Hastelloy X used for?

A: Hastelloy X is used in aircraft engines, industrial furnaces, chemical processing, and power generation applications where strength and oxidation resistance at extreme temperatures are required.

Q: What is the difference between Hastelloy X and Hastelloy C?

A: Hastelloy X has addition of iron and higher molybdenum content. This gives better fabricability and high temperature strength compared to Hastelloy C which relies only on chromium for oxidation resistance.

Q: Is Hastelloy X weldable?

A: Yes, Hastelloy X has good weldability compared to other nickel superalloys, making it suitable for fabrication of complex components. Proper welding process and parameters must be used to avoid cracking.

Q: What is the temperature range of Hastelloy X?

A: It maintains good strength and oxidation resistance up to 1100¡«C for prolonged service. Shorter exposures up to 1200¡«C are possible. Lower temperatures can cause embrittlement.

Q: Is Hastelloy X magnetic?

A: No, Hastelloy X is non-magnetic, with magnetic permeability close to 1. This makes it useful for certain electronic and high temperature applications.

Q: What corrosion environments can Hastelloy X withstand?

A: It exhibits excellent corrosion resistance to oxidizing acids, halogens, sulfidation, and stress corrosion cracking environments found in chemical processing.

Q: Does Hastelloy X contain cobalt?

A: Most grades of Hastelloy X contain 1% or less cobalt. Cobalt-free variants are also available for biomedical applications where cobalt can cause negative health effects.

Q: What are the contents of a Hastelloy X powder MSDS?

A: It provides composition data, health and reactivity hazards, handling guidance, storage requirements, spill and firefighting procedures, transport information and disposal guidelines that are essential to review before use.

Q: Can Hastelloy X powder be 3D printed?

A: Yes, Hastelloy X alloy powders can be used in laser and electron beam powder bed fusion additive manufacturing processes. Parameters are optimized to provide dense, crack-free parts.

Q: How is Hastelloy X powder made?

A: Gas atomization is the common production method where the alloy melt is broken into fine droplets and rapidly solidified into powder. Water atomization is also used either by itself or with gas atomization.

Q: What are the alternatives to Hastelloy X?

A: Alternatives include Inconel 617, Haynes 230, Inconel 625, and stainless steels like 310 and 330. They offer lower cost but cannot match the oxidation resistance of Hastelloy X in extreme environments.
