Heat Treatment Industry Statistics

Global heat treatment is forecast to rise from a USD 109.2 billion market in 2023 to USD 145.6 billion by 2030 at a 3.7% CAGR, even as demand for vacuum heat treatment climbs 5.2% YoY to 1.2 million tons processed. The page pairs that macro growth with hard 2023 benchmarks from leading operators and equipment makers, including Bodycote’s £1.05 billion revenue and SECO WAREWICK’s 120 furnace sales, showing where capacity, technology and spend are shifting fastest.
