Carbon Steel Vs. Stainless Steel: An In-depth Analysis ...
The protective chromium layer makes stainless steel less susceptible to corrosion and rust. Carbon steel, on the other hand, gets easily rusted. Stainless steel is the material of choice in a moist and wet environment. Carbon steel is better used in drier places. Generally, alloys conduct less heat as compared to pure metals.
