Carbon equivalent & its affects on weldability?

Carbon equivalent (CE) is a measure of the weldability of a material, particularly in relation to the heat affected zone (HAZ) during welding. It is a calculation that takes into account the carbon content, as well as other alloying elements that can affect the behavior of the material during welding, such as manganese, silicon, and …

Why PWHT is not required for stainless steel?

Why PWHT Not Required in SS Post Weld Heat Treatment (PWHT) is typically not required in stainless steel. This is because stainless steel has a different microstructure compared to carbon steel, which makes it less susceptible to cracking and hydrogen induced cracking during welding. Additionally, stainless steel has a higher resistance to corrosion, which means …

Why Ni is restricted up to 1% max. for sour service?

Ni Restriction in Sour Service Nickel (Ni) is restricted to a maximum of 1% in sour service due to its tendency to form brittle intermetallics with other metals in the presence of hydrogen sulfide (H2S). This phenomenon is particularly concerning in sour service applications, where H2S is present in high concentrations and can cause corrosion …
