Special Alloys
Depend on PML Monel 400 alloy for outstanding corrosion resistance and durability in marine, aerospace, and harsh chemical environments.
Backed by excellent weldability and cold-working capability, perfect for demanding offshore, oil & gas, and aerospace uses, with proven integrity under extreme conditions.
High-quality Monel 400 alloy ingots produced from virgin elements using Vacuum Induction Melting (VIM).
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.
