Welding, Forming and Heat Treatment of Nickel Alloys
Practical procedures for joining, shaping and heat treating corrosion-resistant alloys: which filler metal matches which parent grade, how to control heat input, where the hot working window sits, and the anneal and ageing cycles that decide whether a grade reaches its specified strength.

How to Weld Hastelloy C276 Without Losing Corrosion ResistancePractical welding guidance for Hastelloy C276 — filler metal selection, heat input limits, interpass temperature, shielding gas and the post-weld cleaning steps that keep the alloy's corrosion resistance intact.Published 2026-09-15
Inconel 718 Heat Treatment: How to Reach Maximum StrengthHow to solution treat and age Inconel 718 to AMS 5662 and AMS 5663 — temperatures, soak times, cooling rates, and the strength you actually get at the end.Published 2026-09-17
How Are Nickel Alloy Flanges Made? Forging, Ring Rolling and StandardsA nickel alloy flange is pinned down by three specifications at once — the alloy, the forging standard such as ASTM B564, and the dimensional standard such as ASME B16.5. This guide covers how a forged and ring rolled flange is made, when a plate-cut flange is acceptable, and what a complete flange purchase order must state.Published 2026-09-18
Forging and Hot Working Temperatures for Nickel AlloysNickel alloys are forged in a narrow window — roughly 120 to 250 C wide — and the correct range is different for every grade. This guide gives typical start and finish forging temperatures for Inconel, Hastelloy, Monel, Incoloy, duplex and titanium, what goes wrong at each end of the window, and how to control heating and heat treatment after forging.Published 2026-09-18
How to Machine Inconel and Hastelloy: Speeds, Feeds and ToolingPractical machining data for Inconel 718, 625 and Hastelloy C-276 — cutting speeds, feed rates, tool grades, coolant strategy and the work-hardening trap.Published 2026-09-17
How Do You Match Nickel Alloy Pipe, Fittings, Flanges and Filler Metal?Match nickel alloy pipe, fittings, flanges and filler metal by UNS grade: which ASTM standard covers each product form, and where ASME dimensions fit in.Published 2026-09-20
Which Filler Metal Should You Use for Nickel Alloy Welding?Which filler metal for nickel alloy welding? Match ERNiCrMo-3 to 625 and ERNiCrMo-4 to C-276 by AWS A5.14 classification, not by trade name.Published 2026-09-20
