The future of metallurgy The future of metallurgy in valve applications will be shaped by advanced materials, sustainability and regulatory chal lenges. Functionally graded materials (FGM), which grad ually transition in composition and microstructure, offer enhanced thermal resistance and mechanical performance. Additive manufacturing (3D printing) allows for complex geometries and tailored material properties, enabling next-generation valve solutions. Despite these innovations, regulatory requirements can slow adoption. Certifications from ASME, API and ASTM ensure safety but also create barriers to new material inte gration. To overcome this, industries must work closely
