Customer Feedback
"This is the first time we've sourced GH3030 seamless tubing from China for our high-temperature furnace tube system. Frankly, we initially had concerns about the quality of nickel-based alloys from Asia. However, the complete EN 10204 3.1 certificate, third-party testing report (SGS), and full traceability documentation provided by Gnee Steel completely reassured us. The grain size, high-temperature tensile properties, and surface quality of this batch of GH3030 tubing fully comply with our Indian domestic IS standards and ASTM B163 requirements. Gnee Steel's technical team even helped us optimize the tubing length tolerances, reducing on-site welding work. This collaboration not only saved us approximately 30% in procurement costs but also established a reliable high-temperature alloy supply chain."

Gnee Steel GH3030 seamless steel tube factory
Gnee Steel GH3030 seamless steel tube specifications:
Outer diameter 10.3mm - 965.2mm, wall thickness 1.0mm - 130mm, annual nickel-based alloy production capacity - 8000 tons/year.
An Indian customer ordered 650 tons of GH3030 nickel-based superalloy seamless steel tubes from us for use in petrochemical cracking furnace tubes and heat treatment tooling projects. The customer has extremely high quality requirements and previously only sourced from Europe and America. However, after multiple technical communications and sample tests with us, the customer decided to visit our factory for on-site inspection and ultimately signed a long-term purchase agreement for 650 tons.
Petrochemical cracking furnace tubes and heat treatment tooling project
GH3030 Material Introduction: GH3030 is an austenitic solid solution strengthened nickel-based superalloy with excellent oxidation resistance and good thermal fatigue properties below 800℃. Similar grades: Incoloy 800H (international), Inconel 600. It is widely used in high-temperature applications such as aerospace engine components, industrial furnace tubes, heat exchangers, and heat treatment fixtures.
Gnee Steel's production equipment
The production of GH3030 seamless tubes employs a dual process of "vacuum induction melting (VIM) + electroslag remelting (ESR)" to ensure material purity.
After hot extrusion, the tube blank is precisely shaped on a multi-pass cold drawing/cold rolling mill, with intermediate bright annealing to eliminate work hardening. Each finished tube undergoes 100% eddy current testing, hydrostatic testing, and final dimensional inspection.
