- The color temperature of steel is closely related to the heating process. At room temperature, steel does not emit light. However, when heated to a certain temperature, it begins to glow, initially emitting a red light. As the temperature rises further, the color of the steel gradually changes from red to orange, and then to yellow.

Apr 1, 2024 · The relationship between the heating temperature of steel and its color: In 1893, Wien studied the relationship between the maximum wavelength λmax and temperature T, which is λmaxT=2898μm•K. Therefore, the temperature can be judged based on the color of the flame (i.e., the wavelength of light).

What happens when steel is heated?
Unlike coloring steel with paint and opaque patinas, heat colors are transparent and integral to the substrate. They allow you to patina the metal without obscuring its metallic character. And because they color the metal while enhancing its dynamic and reflective qualities, they are directly influenced by any decorative surface grinding.

Tempering is a method of heat treatmentusually performed after quenching, where the steel is reheated to a precise temperature below the lower critical temperature and holding (or soaking) it there. Heating above that critical temperature is avoided because it will destroy the strong microstructure from quenching, called martensite. After a set tim...
Depending on the temperature that the steel is held at during tempering, the metal actually changes its color. Lower tempering temperatures primarily relieve internal stresses and slightly lower the brittleness, while higher temperatures (up to the critical temperature) result in larger decreases in brittleness. This sacrifices yield and tensile st...
When a piece of steel is tempered, a thin oxide layer forms on the surface of the metal. As the temperature increases, the steel oxidizes more easily and deeper. Depending on the depth of this layer, specific wavelengths are enhanced and reflected, while others are absorbed. What we see is the reflected wavelengths, which changes the color based on...

Apr 24, 2017 · When heating steel it's important to understand how different temperatures affect the color and chemistry of the steel. Working with steel and modifying its color involves setting up a sufficient heat source, heating the steel to the desired color, then quenching and tempering it.
May 17, 2024 · When steel is heated, it emits light at different wavelengths. The color of this light corresponds to the temperature of the steel. The Steel Color Temperature Chart provides a visual guide to estimate steel temperature based on its color.
