From our DLX melt experts, Nimonic 75 is a nickel-chromium workhorse – nickel around 75-80% for that core heat endurance, chromium 18-21% forming a tight oxide scale that blocks corrosion in air or gases. Titanium 0.2-0.6% adds hardening without overcomplicating, iron max 5%, carbon 0.08-0.15% for strength tweaks, and manganese/silicon under 1% for deoxidation. No heavy cobalt or molybdenum here – keeps it simple and affordable while hitting UNS N06075 specs. Density? 8.37 g/cm³, so it's sturdy without weighing down your designs.
On the props front, it's built for steady high-heat duties. Annealed, yield sits at 250-350 MPa, tensile 600-800 MPa, elongation 30-40% for easy drawing into wires or forming baskets. Crank temps to 900°C, and it retains 200 MPa tensile with minimal creep – oxidation barely phases it up to 1000°C continuous, 1100°C intermittent. Thermal conductivity 11.7 W/m·K at room temp, expansion 13.1 x 10^-6 /°C – balanced to handle thermal cycles without cracking. Corrosion? Strong in oxidizing atmospheres, resisting scaling and carburization, though not ideal for sulfides or halogens without coatings. Welds like a dream with TIG/SMAW, machines at 20-30 m/min with carbides, and draws into 0.1-6mm diameters flawlessly. At DLX, we arc-melt in vacuum for low impurities, ensuring consistent batches that meet aerospace-level certs even for industrial use – plus, it's 95% recyclable, syncing with eco drives in our scrap-based runs.
Bottom line: Nimonic 75 nails cost-effective durability for mid-to-high temps – and we optimize it for your furnace fights.

This alloy thrives where heat is the boss. Heat treatment? It's our fave – fixtures, trays, and baskets that cycle through 900°C anneals without warping, keeping shapes for thousands of hours in carburizing or nitriding vibes. We've wired up quenching racks for auto parts makers, cutting replacements 40% thanks to its scale resistance.
Furnace components? Killer – radiant tubes, muffles, and retorts in industrial kilns shrug off oxidation in glass or ceramic firing. Gas turbine engineering still digs it for non-critical parts like supports or seals, enduring hot gases without pitting. Chemical plants coil it for catalyst grids in thermal crackers, and power gen uses it in boiler hangers for steam at 800°C. At DLX, we tailor: fine wires for thermocouples, heavier for chains or belts – annealed for fab ease. It trims costs 20-30% over cobalt-heavy alloys while doubling life in oxidizing setups, boosting uptime from steel mills to aerospace preps. If your op involves sustained heat without extreme creep loads, Nimonic 75 from DLX keeps it running smooth.

FAQs:
We field these often – here's the lowdown.
Oxidation resistance secret? Chromia layer forms a barrier up to 1100°C, with Ti stabilizing for long hauls in furnaces without flaking.
Creep handling? Decent at 900°C under moderate loads; not for extreme stresses but outlasts plain steels in heat-treat cycles.
Welding ease? TIG or MIG with matching filler, no preheat needed – low cracking, post-weld anneal optional for full props.
Fatigue in cycles? Good for 10^6 thermal shocks, ductility keeps it flexing in kiln doors or baskets.
Low-temp use? Stays tough to -100°C, no brittleness for mixed industrial apps.
Machining tips? Low work-hardening; HSS tools at 30 m/min, coolant heavy – simpler than aged supers.
Eco benefits? High recyclability, our low-carbon melts fit sustainability audits for furnace ops.
DLX sizes and turnaround? 0.1-6mm dia, coils or cuts; 2-4 weeks stock, 6 customs – speedier than averages.
