However, it is difficult to relate this then to hardness or microstructure. The microstructure and hardness produced in any ferritic steel heat affected zone (HAZ) is essentially dependent upon: the cooling rate through the transformation temperature range of the steel in question. the composition and the hardenability of the steel, andSee all results for this questionWhat are the effects of carbon content on hardness?The effects of carbon content on the hardness of highvanadiumhigh-speedsteelshaveshownthathard- ness increases sharply as a functionof the carbon con- tent with up to 2.25% and slowly more than 2.25%.

In general, as the carbon content increases the hard- ness of the steel also increases, while the elongation decreases.See all results for this question
The effect of carbon on hardening is mainly via the short-rangeterm. In summary, the measurements of microhardness and tensile tests of medium-carbon steels with the different carbon content (0.30 to 0.55 wt.%) have shown that . y, UTS, and hardness increase with an increase of carbon content at room temperature.See all results for this questionHardness, microstructure and toughness in steel HAZ - TWIThe microstructure and hardness produced in any ferritic steel heat affected zone (HAZ) is essentially dependent upon: the cooling rate through the transformation temperature range of the steel in question. the composition and the hardenability of the steel, Hardness and micro structural gradients in heat affected effect on hardness micro structuralHardness and micro structural gradients in heat affected zone of welded low carbon quenched and tempered steels. effect on hardness micro structural This phenomenon, referred to as the displaced hardness peak (DHP) effect, is effect on hardness micro structural
