What’s on the Heat Treating Steel poster
A 5-row table: Treatment · What happens · Result.
For plain carbon and low alloy steels.
- Annealing — Slow cool from austenite — Soft and machinable
- Normalising — Air cool from austenite — Uniform grain, tougher
- Quenching — Fast cool to martensite — Very hard, very brittle
- Tempering — Reheat after quenching — Trades hardness for toughness
- Case hardening — Add carbon at the surface — Hard skin, tough core
Hardening needs carbon: below about 0.3 per cent, plain steel will not harden usefully by quenching.
Questions about the Heat Treating Steel poster
- What’s on the Heat Treating Steel poster?
- A 5-row table: Treatment · What happens · Result. For plain carbon and low alloy steels.

- Who is the Heat Treating Steel poster for?
- Heat Treating Steel belongs to the Mechanical Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning manufacturing can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Heat Treating Steel poster?
- Specifying a steel part's condition, or explaining why one cracked on quench. A wall chart earns its place by being glanceable from where the work is happening, so Heat Treating Steel belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.
- What other posters go with Heat Treating Steel?
- Additive Processes, Casting Processes and Speed & Feed sit alongside Heat Treating Steel in the Mechanical Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Additive ProcessesCasting ProcessesSpeed & Feed
- Is the Heat Treating Steel poster free to download and print?
- Yes. Heat Treating Steel downloads as a free PDF with no account, no email and no watermark, like everything else in the Mechanical Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Heat Treating Steel poster print at?
- Heat Treating Steel is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Heat Treating Steel loses nothing.Printing guide
