Hastelloy is a trademark for a group of corrosion-resistant metal alloys. The alloys are mostly nickel. They also contain molybdenum, iron, cobalt, and chromium in different amounts. Hastelloy is part of the “superalloy” family. It resists corrosion and oxidation. It maintains strong mechanical strength at high temperatures.
Common Grades
Hastelloy C-22: Very good against oxidizing environments and chloride media.
Hastelloy C-276: Very common grade. Resists many chemical processes.
Hastelloy B-2: Very strong against hydrochloric acid and reducing environments.
Choosing the right grade needs checking factors for your project. Below, we show how Hastelloy compares to other metals. This helps you decide.
Is Hastelloy Stainless Steel?
Hastelloy and stainless steel are different.
Stainless Steel
Iron-based alloy with at least 10.5% chromium.
Common grades: 304 and 316.
Works for many uses but is weak in strong acids and harsh chemicals.
Hastelloy
Nickel-based alloy with high nickel and molybdenum. Some grades have chromium, iron, or cobalt.
Made for tough environments like acids, seawater, and strong oxidizing or reducing conditions.
Costs more than stainless steel.
Both resist corrosion. Hastelloy is a nickel superalloy, not stainless steel.
Is Hastelloy the Same as Inconel?
Hastelloy and Inconel are not the same. Both are nickel alloys. They have different compositions and strengths.
Hastelloy
Matrix: Nickel + molybdenum. Some grades add chromium.
Strength: Very strong against acids (HCl, H₂SO₄, H₃PO₄) and reducing agents.
Use: Chemical plants, pollution control, marine settings, flue gas scrubbers, and corrosive equipment.
Inconel
Matrix: Nickel + chromium, with some iron, molybdenum, or niobium.
Strength: Very good against heat and oxidation. Works at very high temperatures (~1000°C / 1830°F).
Use: Aerospace, gas turbines, jet engines, nuclear reactors, and high-temperature furnaces.
Hastelloy is best for corrosion. Inconel is best for heat and oxidation. Choose based on what is more important for your project.
How to Cut Hastelloy?
1. Cutting Methods
Bandsaw: Good for bars, ingots, and thick plates. Use carbide or bimetal blades, low speed, and coolant.
Waterjet: Good for thin plates and complex shapes. No heat zone. Keeps corrosion resistance.
Laser: Works for thin plates. Slower than stainless steel. Needs a high-power fiber laser.
Plasma: Works for thick plates. The surface may need grinding.
Machining (Milling, Turning): Use carbide tools at low speed and cooling.
2. Key Techniques
Keep tools sharp. Hastelloy hardens fast.
Use a low cutting speed and high feed. Avoid overheating.
Use lots of coolant. Protect tools.
Clamp workpiece. Reduce vibration.
3. Safety
Cutting makes dust. Wear a mask. Keep air moving.
Edges are sharp. Handle carefully.
How much is Hastelloy?
Hastelloy price is not fixed. It depends on:
Order size
Product form (sheet, tube, bar, fittings)
Delivery and shipping
Raw material cost (nickel, molybdenum)
