With a grasp of what changes are actually taking place in the metal the care needed in following the practical processes described becomes understandable and will lead to better and more consistent results. Flame, salt bath and furnace heating are detailed, with information on accurate measurement or recognition of temperature levels. For the average small workshop operative or model engineer the discourses on tool material, hardening and tempering will be of most use, and in this connection this book replaced the author's earlier Hardening and Tempering Engineers' Tools, providing a broader-based, more detailed and up to date examination of the subject. Review: This is a good book for learning the basics. - Having worked 50 years in the industry of mechanical engineering, there is a lot more to know, but this is a good starting point. There are better graphs and pictures in other more modern books. I recommend looking for other sources that are out there. To supplement this book. Tubal Cain is a real character in the Bible. This Tubal Cain has written lots of other books and is well known in model engineering circles Especially in Britain. Review: Guida per il fai da te senza troppe pretese scientifiche - Una guida breve di scuola anglosassone (pregi e difetti), quasi esclusivamente dedicata agli acciai al carbonio e molto poco agli acciai che comunemente si utilizzano negli utensili moderni (punte da trapano comprate al ferramenta). Pubblicazione abbastanza datata che risulta ancora attuale per i falegnami. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #814,831 in Books ( See Top 100 in Books ) #4,335 in Design & Fashion (Books) #35,470 in Crafts, Hobbies & Home #59,198 in Sciences, Technology & Medicine (Books) | | Customer Reviews | 4.6 out of 5 stars 731 Reviews | ## Images ![Hardening, Tempering and Heat Treatment: The Secret Healing Power Of Essential Oils - Image 1](https://m.media-amazon.com/images/I/71-CCoIEO5L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ This is a good book for learning the basics. *by J***H on 16 April 2022* Having worked 50 years in the industry of mechanical engineering, there is a lot more to know, but this is a good starting point.

Pubblicazione abbastanza datata che risulta ancora attuale per i falegnami. ### ⭐⭐⭐⭐⭐ Good general knowledge. *by D***L on 10 January 2024* I am a retired machinist and most parts that needed heat treating would have been sent out. On some occasion parts would be hardened in the shop but this book would have been a lot of help. I would buy again. ## Frequently Bought Together - Hardening, Tempering and Heat Treatment (Workshop Practice Series) - Soldering and Brazing: 9 (Workshop Practice Series) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/126735640-hardening-tempering-and-heat-treatment-the-secret-healing-power-essential](https://www.desertcart.us/products/126735640-hardening-tempering-and-heat-treatment-the-secret-healing-power-essential) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-18*
