From our DLX melt masters, GH3030 is an 80% nickel-20% chromium solid-solution alloy, with titanium 0.15-0.35% adding that extra oxide stability and minor hardening. Iron, manganese, and silicon are kept under 1% each to maintain purity, carbon maxes at 0.10% to avoid carbide woes, and phosphorus/sulfur are ultra-low (≤0.020%) to dodge brittleness. No heavy molybdenum or niobium here – keeps it straightforward and cost-effective while hitting UNS or GB/T specs. Density clocks in at 8.40 g/cm³, light enough for easy handling but tough for high-heat duties.
Mechanically, it's built for balance. Annealed, room-temp yield around 240-310 MPa, tensile 600-750 MPa, elongation 35-45% for smooth coiling or stamping into complex shapes. Crank to 700°C, and it retains 150-200 MPa tensile with creep under 1% in 1000 hours at 80 MPa stress – oxidation shrugs off 800°C continuous, forming stable chromia layers that resist spalling in air or mildly corrosive gases. Thermal conductivity ~15 W/m·K at RT, expansion 14.0 x 10^-6 /°C – tuned to minimize warping in cycles. Corrosion? Solid against aqueous acids, alkalies, and dry gases; resists stress cracking in chlorides better than many. Welds like a dream with GTAW/SMAW (no preheat, low hot-cracking), machines at 25-35 m/min with HSS tools. We draw it into 0.1-5mm diameters at DLX, arc-melting in vacuum for <10 ppm impurities – recyclable to 95%, aligning with our scrap-based runs that slash environmental impact.

GH3030 wire excels where corrosion and heat collide. Chemical processing? Our fave – drawn for reactor linings or valve stems in nitric or sulfuric plants, enduring mixed acids at 500°C without pitting. We've supplied coils for heat exchanger tubes in petrochemical crackers, where oxidation resistance cuts leaks 35% and boosts run times. Heat processing? Furnace muffles and retorts handle 800°C annealing without scaling, perfect for metalworking kilns or glass melting.
Aero sneaks it for non-critical exhaust parts resisting fuel gases, while power gen uses it for boiler supports in steam at 600°C. At DLX, we tailor: fine wires for thermocouples in corrosive monitors, heavy for baskets in heat-treat ovens – annealed for formability. It slashes replacements 25% over irons while handling thermal shocks, amping efficiency in desal to pharma. When atmospheres turn nasty, GH3030 wire from DLX holds the line.
