GH3030 is often referred to as "heat-resistant steel," but strictly speaking, it is a high-performance nickel-based superalloy. It is specially designed to outperform standard stainless steel in extreme high-temperature environments.
Our GH3030 heat-resistant sheets are designed for extreme environments. Even when operating at temperatures above 800°C, they maintain excellent structural integrity and oxidation resistance. Whether you are manufacturing aerospace components or industrial heating equipment, our GH3030 sheets meet the reliability requirements of your projects.

FAQ
Q1: Is GH3030 a stainless steel or a nickel alloy?
A: GH3030 is a nickel-chromium based superalloy. While it contains some iron, its high nickel content (>75%) classifies it as a nickel alloy, offering much better heat resistance than 300-series stainless steels.
Q2: What is the equivalent grade for GH3030?
A: GH3030 is chemically similar to Nimonic 75 and is often used in applications requiring ASTM B168 standard properties for nickel-chromium-iron alloys.
Q3: Can GH3030 be easily welded?
A: Yes, GH3030 has excellent welding performance. It can be joined using argon arc welding (TIG/MIG) or resistance welding without the risk of post-weld cracking.
Q4: Do you offer free samples?
A: We can provide small material samples for chemical analysis and hardness testing. Please contact our sales team for details.
