What Makes Carbon Steel And Stainless Steel Knives Different? (tastingtable.com)
There are two kings of the kitchen - the carbon steel knife and the stainless steel knife. (tastingtable.com)
The costs for carbon and stainless steel kitchen knives can range widely, but what exactly are you paying for? (tastingtable.com)
Carbon steel is a mix of iron and carbon. (tastingtable.com)
According to Wasabi, carbon steel should be between 98-99% iron and 1-2% carbon. (tastingtable.com)
Pure iron is soft, so carbon is added to harden the blade, and this combination makes a carbon steel knife so desirable. (tastingtable.com)
Because of its hardness, carbon steel retains its sharpness for much longer than stainless steel and makes at-home sharpening much simpler. (tastingtable.com)
Chipping can occur more easily in a carbon steel knife versus a stainless steel knife. (tastingtable.com)
Another downside to carbon steel knives is the high rust factor. (tastingtable.com)
Moisture and acidic foods can cause a high-carbon steel knife to rust within hours. (tastingtable.com)
This patina can even serve as a protective coating for carbon steel, preventing further rusting, according to Wasabi. (tastingtable.com)
A carbon steel knife requires more care to prevent corrosion from iron oxide rust. (tastingtable.com)
Hunker suggests washing your carbon steel knife immediately after use, drying thoroughly, and lightly rubbing the blade with food-grade mineral oil before storing. (tastingtable.com)

It can be seen that when t γ is low (880 ℃), the carbon content in austenite of nodular iron with pearlite matrix is higher than that of nodular iron with ferrite matrix after austenitizing treatment. (zhycasting.com)
However, when the t γ is high (920 ℃, 960 ℃), more carbon elements are more easily enriched in the high temperature austenite after austenitizing the nodular iron with ferrite matrix. (zhycasting.com)
In addition, no matter how the casting modulus and the amount of pearlite change, the carbon concentration in austenite does not change significantly after 1.7h holding time. (zhycasting.com)
This indicates that austenitizing temperature is a significant factor to determine the carbon concentration in austenite. (zhycasting.com)
