Inconel 625 sheet combines high strength, excellent corrosion resistance, and fabrication ease in a single product. This nickel-chromium-molybdenum superalloy is specified for tasks that demand reliable behaviour in harsh settings and meets the ASTM B443 and AMS 5599/5666 requirements for critical service.

The alloy also proves remarkable for long-term body-contact devices such as cardiovascular implants, thanks to its good biocompatibility, low antigen response, enduring fatigue performance in saline, and capacity to be formed into intricate geometries without losing strength.

Niobium-rich nickel-base alloys show outstanding resistance across a wide spectrum of corrosive media. Their exceptional toughness and strength arise largely from the niobium addition, which limits pitting, crevice attack, flow-assisted erosion, intergranular damage, and stress corrosion links stressed by chlorides.

The nickel-chromium-molybdenum-niobium blend keeps most of that strength in the soft-annealed condition, eliminating a need for hardening heat treatments. Its high-temperature stability also fits aircraft engines, power-generation turbines and marine hardware demanding repeated heating and cooling cycles.

Components cut in standard workshop sizes go together easily with basic shop equipment, and gas-tungsten arc welding, shielded metal arc welding, or submerged-arc welding will make strong joints. The alloys wide ductility encourages cold working, yet the material hardens quickly, so operators may find light annealing between major stages useful to bring strength and toughness back into balance.


Inconel 625 data sheet

Kanakratna Steel Age stocks Inconel 625 sheet in sizes ranging from thin sheets and strips to thick plates, plus round rods, bars, seamless tubes and pipes, welded pipes, and a full line of forged fittings, flanges, and valves. Outstanding high-temperature strength combined with broad corrosion resistance makes this nickel-chromium-molybdenum alloy a preferred choice for pressure vessels facing severe environments.

Controlled niobium and molybdenum additions reinforce the nickel-chromium lattice, avoiding the need for aging treatments that other alloys require. This chemistry gives the material very high resistance to pitting in acidic solutions, prevents chloride-induced stress-corrosion cracking, supports strong fatigue performance, permits easy welding to dissimilar metals, and protects equipment deployed in tidal or marine applications, including seawater systems.

Inconel 625 Material Properties

Inconel 625 is a nickel-chromium-molybdenum superalloy widely recognized for its adaptability in tough environments. The material stands out because it retains strength, ductility, and corrosion resistance from cryogenic temperatures to about 980C in air or 870C in non-oxidizing gases; it endures repeated thermal cycling without significant loss of integrity.

Pitting, crevice, and stress-corrosion cracking are virtually eliminated, making the alloy ideal for sea-water service, chemical processing, and gas-turbine components. Long product forms, including bars, wire, cut-to-length sheets, welded tubes, pipe fittings, flanges, and custom forgings, let engineers specify a single material across an entire assembly.

Fabricators appreciate that Inconel 625 can be formed and joined using standard tools and procedures. Cold rolling, hot forging and electron-beam welding yield smooth, crack-free seams, while C- or high-nickel electrodes restore properties during repair work. Because work hardening increases strength without brittleness, the alloy machines acceptably with carbide or ceramic inserts at moderate speeds and generous coolant flows, and sulphur-free lubricant suppliers minimize chip-welding.

Testing shows fatigue-limit stress exceeds 200 MPa even after millions of cycles, which, combined with high yield strength, restricts macrostress concentration and satisfies aerospace, subsea, or power-generation reliability targets.

Inconel 625 sheet by kanakratna steelage provides outstanding resistance to corrosion. The alloy resists pitting and crevice attack in environments including organic acids, and it shows nearly complete immunity to stress-corrosion cracking caused by chlorides.

Inconel 625 can be cold-formed or hot-worked using standard shop techniques. Because it hardens faster than many stainless steels, however, operators need strong machinery, keen edge tools kept at positive rake angles, and careful chip removal to avoid damaging newly hardened areas during machining.

Price trends for Inconel 625 sheet in India vary with market conditions; volatility in supply and demand means that costs change.

This nickel-base superalloy resists oxidation and corrosion from cryogenic temperatures up to 1800 C thanks to alloying nickel, molybdenum, and niobium into a coherent matrix, while also avoiding chloride-related pitting or stress-corrosion cracking.

These alloys combine high tensile strength with exceptional resistance to creep, rupture, forming, and welding-characteristics that make them valuable in aircraft assembly, structural fabrication, and chemical processing plants. They are also easy to install, remarkably durable, and designed to last under demanding working conditions.
