Special Alloys
Depend on PML Tribaloy T400 for exceptional wear resistance and corrosion protection in highly demanding applications.
Designed for investment casting applications across aerospace, engineering applications such as mechanical seals, extrusion dies, cutting tools, and industrial sectors.
High-quality Triballoy T400 alloy ingots manufactured using air melting with argon gas purging to ensure material purity and structural integrity.
Alloy chemistry and ingot specifications are finalized as per application requirements.
As per customer requirements, 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.
Virgin elements are charged into the VIM furnace either in air or under vacuum, with precise adjustments made for trace element additions during melting.
The melt is poured under vacuum into precision-engineered molds using an automatic tilting mechanism for defect-free solidification.
Post-casting processes include surface treatment, cropping, and preparation of ingots for downstream processing.
Every batch is tested for chemical composition by Spark- OES / wet analysis / Gas analysis, and physical compliance as per customer specification before secure packaging.
