Nimonic alloy Round bar Stockist & Supplier

Shree Sambhav Alloys is one of the well known Nimonic Alloy Round bar Stockist. Nimonic is ideally used in the making of aircraft parts and also in gas turbine blades since it is capable of withstanding extreme temperature and pressure conditions. The unmatched quality and unsurpassable performance has attracted various national as well as international clients to place bulk orders for these products. Additionally, customers are facilitated with their availability in varied sizes, dimensions and grades like Nimonic Alloy 80A and Nimonic Alloy 75, as per the specifications and drawings provided.

Nimonic Alloys 80A

Nimonic Alloy 80A (Nimonic® alloy 80A) is a wrought, age-hardenable nickel-chromium alloy similar to NIMONIC alloy 75 but made precipitation hardenable by additions of aluminum and titanium. The alloy has good corrosion and oxidation resistance and high tensile and creep-rupture properties at temperatures to 1500°F (815°C). Used for gas-turbine components (blades, rings, and discs), bolts, tube supports in nuclear steam generators, die-casting inserts and cores, and exhaust valves in internal-combustion engines.

Specifications :- Nickel-Chromium Alloy; UNS N07080; BS 3076 (NA 20), HR1, HR201, HR401, HR601; ASTM B 637; DIN 17742, 17754, Werkstoff Nr. 2.4952, 2.4631; WL Nr. 2.4631, AFNOR NC 20TA; AECMA Pr EN 2188 - 2191, 2396, 2397

Available Product Forms : Sheet, plate, round bar, flat bar, forging stock, hexagon, wire and extruded section

Nimonic Alloys 90

A precipitation-hardenable nickel-chromium-cobalt alloy having high stress-rupture strength and creep resistance at temperatures to about 1700°F (920°C). The alloy also has good resistance to high-temperature corrosion and oxidation. Used for blades and discs in gas turbines, hot-working tools, and springs.

Specifications :- UNS : N07090

Available Product Forms : Sheet, strip, plate, round bar, flat bar, forging stock, extruded section and wire

Nimonic Alloys 75

Alloy 75 (UNS N06075, Nimonic 75) is a 80/20 nickel-chromium alloy with controlled additions of titanium and carbon. Nimonic 75 has good mechanical properties and oxidation resistance at high temperatures. Alloy 75 is most commonly used for sheet metal fabrications which require oxidation and scaling resistance together with medium strength at high operating temperatures. Alloy 75 (Nimonic 75) is also used in gas turbine engines, for components of industrial furnaces, for heat treating equipment and fixtures, and in nuclear engineering.
