The four heat treat industry-specific economic indicators have been gathered by Heat Treat Today each month since June 2023. As the northern hemisphere looks to warmer weather, a positive outlook is reflected in three of the four economic indicators compiled in the first week of March.
Heat treat industry suppliers anticipate the economy in March to experience growth in number of inquiries, value of bookings, and size of backlog, however there is a net decrease compared to February. This is particularly shown in the economic indicators where suppliers to the North American heat treat industry expect no change over previous months in health of the manufacturing economy.
The results from this month’s survey (March) 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 February to March: 61.1
- Anticipated change in Value of Bookings from February to March: 58.8
- Anticipated change in Size of Backlog from February to March: 59.5
- Anticipated change in Health of the Manufacturing Economy from February to March: 50.0
