stainless steel tempering colours

One important point to note is that tempering steel color appears above 200 o C. Below this temperature, oxidation of steel occurs but thickness is very less resulting in no tempering steel color. The table below represents the temper colours that are likely to form on stainless steel type 1.4301 (AISI 304) if heated in air. Fix? Support the stainless steel item with your tongs and heat it evenly in the kiln. Color Choices. Heat tint (temper) colours on stainless steel surfaces The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. I have no experience whatsoever and tried to do some research but in the end it still was a little too complicated for me to grasp exactly what happens to the steel after the process and what will be the effects on durability and hardness. 20% oxygen) is assumed. This is a phenomenon called tempering. 440C). This stainless steel skillet is about 10 years old now and still working as well as the day I bought it. So the straw-colored range indicates a harder steel but its more brittle. The level of oxygen available for the oxidation process also affects the colours formed. Oil?

I first torched it with a propane torch (blue pointy flame) and I guess overheated it because it went through gold violet blue and turned gray. While it's not going to harden it and make it brittle, thermal shock is never a good thing. Heat Temper Colours on Stainless Steel Surfaces Heated in Air. However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. As the colours formed are by light interference, then the smoothness of the surface can also affect the appearance of the colours formed. The chromium content is the most important factor affecting oxidation resistance. Sorry for the long post and thank you for any replies. I know its a bit long.

Steel in a tempering oven, held at 205 °C (401 °F) for a long time, will begin to turn brown, purple or blue, even though the temperature did not exceed that needed to produce a light-straw color. The term "stainless steel" refers to several types of steel that contain small amounts of chromium, which helps the steel resist rusting and corrosion. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Gradually raise the heat of the kiln to the austenitising temperature and allow the item to reach a moderately red color. you shouldnt worry to much, its a pen, not the highest stress use case, a little less tensile strength or a little weaker threads wont do much. This includes but is not limited to welding, machining, casting and general fabrication. Second attempt I sanded down the oxide and got a mixed result with some places overheated and some still gold because for some reason it didn't want to change color anymore even though the spot was beginning to lightly glow red under the torch. The colour of a piece of polished steel after it has been tempered in air. The only thing achieving by doing it is saving a completely insignificant amount of time.

However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. Many experts on surgical stainless steel say that the bluish tint is a tempering of the surface of the steel as a result of overheating, and cannot be removed. Laboratory tests done to establish the published heat tint colour charts have usually been based on heating for one hour. Heat treatment methods, such as stress relieving, hardening and annealing, strengthen the ductility and corrosion resistance properties of the metal that is modified during fabrication, or generate hard structures capable of tolerating abrasion and high mechanical stresses. Tool steels make excellent cutting and drilling equipment as they contain tungsten, molybdenum, cobalt, and vanadium to increase heat resistance and durability. in the water where I live it is getting water spotted but still comes clean from food and use.
