In these areas, chromium content drops below 10,5% and steel will lose its ability to form a passive film and will no longer be stainless. The result is the so-called intergranular corrosion. In extreme cases, metal will turn black.

What is the Heat Affected Zone (HAZ)? - TWI

The heat affected zone (HAZ) is a non-melted area of metal that has undergone changes in material properties as a result of being exposed to high temperatures. These changes in material property are usually as a result of welding or high-heat cutting. The HAZ is the area between the weld or cut and the base (unaffected), parent metal.What are the side effects of HAZ in stainless steel?As a result of this, the HAZ is often the area where failures occur. Furthermore, in stainless steels, surface nitriding can lead to increased hardness and a decreased weldability. Corrosion is another common side-effect of the high temperatures experienced by the HAZ in stainless steels.See all results for this questionThe heat affected zone of X20Cr13 martensitic stainless the heat affected zone of x20cr13 martensitic stainlessDec 01, 2020 · Multiple repair welding of X20Cr13 martensitic stainless steel was performed using gas metal arc welding.

The corrosion resistance of austenitic stainless steel fittingsAll you need to know about the heat-affected zoneThe most important factor that influences the creation of the HAZ is thermal diffusivity. Technically speaking, this coefficient depends on thermal conductivity, density, and specific heat of a substance. Materials that show a high thermal diffusivity are able to quickly transfer variations in heat, rather than heat itself. In other words, if a material demonstrates high thermal diffusivity, it cools faster, and HAZ is reduced.
