Heat Treat Today has gathered the four heat treat industry-specific economic indicators for September 2025. August industry-specific economic indicators showed stagnation with hope for a future upswing and September predicts a positive surge of growth.
September’s industry-specific economic indicators showed all four indices jumping into growth. The Inquiries index rose from no change into growth at 56.0 (from 50 in August). Bookings leaped up to 64.4 (from 47.2 in August). The Backlog index rose to 59.3 (from 46.3 in August). Finally, the Health of the Manufacturing Economy index increased to 58.4 (compared to 48.0 in August).
The graphs overall suggest that the undercurrent of growth, which began in late summer, is seeing a substantial increase, giving hope for a positive fourth quarter of 2025.
The results from this month’s survey (September) are as follows: numbers above 50 indicate growth, numbers below 50 indicate contraction, and the number 50 indicates no change:
- Anticipated change in Number of Inquiries from July to August: 56.0
- Anticipated change in Value of Bookings from July to August: 64.4
- Anticipated change in Size of Backlog from July to August: 59.3
- Anticipated change in Health of the Manufacturing Economy from July to August: 58.4
