Hastelloy G-30 Seamless Pipe Tube (UNS N06030 / W.Nr. 2.4603)
High-strength corrosion-resistant alloy pipe tube for chemical and aerospace industry
As a professional supplier of high-performance nickel alloys, SEATHER TECHNOLOGY supplies Hastelloy® G-30 seamless pipes and tubes engineered for severe corrosion and high-temperature service environments.
Hastelloy G-30 is a nickel-based alloy offering excellent corrosion resistance and thermal stability. It performs exceptionally well in strong acids, highly oxidizing media, and complex corrosive conditions, particularly in phosphoric acid, sulfuric acid, and mixed acid systems. These characteristics make Hastelloy G-30 seamless pipe and tube an ideal choice for critical applications in the chemical processing, petroleum, energy, and environmental protection industries.
SEATHER TECHNOLOGY applies strict quality control and comprehensive inspection procedures to ensure the performance and reliability of every Hastelloy G-30 seamless pipe and tube. Each product undergoes hydrostatic testing, in which internal water pressure exceeding the specified working pressure is applied to verify pressure integrity and leak-tightness. In addition, eddy current testing is conducted using electromagnetic induction techniques to precisely detect surface and near-surface defects such as micro-cracks, inclusions, or porosity.
The combination of these critical inspection methods ensures structural integrity, operational safety, and long-term durability, enabling SEATHER Hastelloy G-30 seamless pipes and tubes to meet the stringent requirements of demanding industrial applications.

What is Hastelloy G-30 (UNS N06030)
Alloy G-30 also referred to as the UNS N06030/W.Nr. 2.4603 alloy.
Alloy G-30 is a nickel-chromium-iron material highly resistant to “wet process” phosphoric acid.
As a result of its high chromium content, G-30 alloy is also very resistant to other oxidizing acids, such as nitric, and mixtures containing nitric acid. It possesses moderate resistance to reducing acids, such as hydrochloric and sulfuric, as a result of its appreciable molybdenum and copper contents.
Alloy G-30 is widely used in reactors and heat exchangers.
Alloy G-30 is available in the form of plates, sheets, strips, billets, bars, wires, pipes, tubes, and covered electrodes.
