material selection
3 in-depth engineering guides on material selection — specification, selection, testing and procurement.
Everything on material selection
Vajra's engineering team has published 3 technical guides covering material selection for industrial valve selection, specification, testing and procurement. Browse the full set below.
High Alloy Valves: Hastelloy C-276, Inconel 625, Monel 400 - When and Why
Hastelloy C-276, Inconel 625, and Monel 400 valves are specified when carbon steel and stainless steel 316L cannot provide adequate corrosion resistance - here's exactly when each alloy is the right choice.
Valve Body Material Selection Guide: WCB, CF8M, SS 316L, Duplex, Hastelloy - When to Use Each
Choosing the wrong valve body material is the most expensive procurement mistake in process plant design. This guide walks through the five main categories: carbon steel, stainless steel, duplex, nickel alloy, and lined - and when each is the right choice.
Valve Selection for Chemical Plants: Materials, Standards & Fugitive Emissions
Chemical plants handle acids, alkalis, solvents, and highly toxic fluids - valve material failures cause catastrophic releases. This guide covers the material selection matrix for corrosive chemical service, NACE MR0103 requirements for refinery service, fugitive emissions ISO 15848 compliance, and the role of polymer-lined valves.
