Super Alloys
Nimonic 80A
High-strength nickel alloy for high-temperature structural applications
High-Temperature Resilience: Nimonic 80A for Extreme Thermal Performance
Designed for service temperatures up to 815°C, Nimonic 80A combines high tensile strength, creep resistance, and oxidation stability.
Ingot Manufacturing Process
Manufactured from virgin raw materials using Vacuum Induction Melting (VIM) technology to ensure controlled chemistry and minimal impurities.
RFQ from Customer
Alloy chemistry and ingot specifications are finalized as per application requirements.
Alloy Design/Planning
As per customer requirement mould design carried out and planned for charge preparation, charge sequences in VIM furnace. Careful selection of raw materials are the prime factor to achieve specified chemistry of an alloy.
Alloy Melting by VIM
Virgin elements are charged into the VIM furnace either in air or under vacuum, with precise adjustments made for trace element additions during melting.
Process & Quality Control
The melt is poured under vacuum into precision-engineered molds using an automatic tilting mechanism for defect-free solidification.
Primary Finishing
Post-casting processes include surface treatment, cropping, and preparation of ingots for downstream processing.
Testing & Packaging
Every batch is tested for chemical composition by Spark- OES / wet analysis / Gas analysis, and physical compliance as per customer specification before secure packaging.
