Low hardenability
Did you know?
The hardenability of a metal alloy is the depth to which a material is hardened after putting it through a heat treatment process. It should not be confused with hardness, which is a measure of a sample's resistance to indentation or scratching. It is an important property for welding, since it is inversely proportional to weldability, that is, the ease of welding a material. Web25 feb. 2024 · Therefore lower temperatures can sometimes mean lower hardenability …
Web14 apr. 2024 · Its biggest weakness is low hardenability, and it is not suitable for workpieces with large cross-sectional dimensions and relatively high requirements. PMC low temperature resistant seamless pipe, using low-sulfur, low-phosphorus, high-purity steel and calcification treatment, can effectively reduce the low-temperature brittleness … Web3 nov. 2024 · Low melting temperature metals make control of weld pool difficult and sensitive for melt through especially in case of thin sections while high melting temperature metals impose difficulty in melting of faying surfaces.
