What are the differences between stainless steel and carbon steel?

Carbon steel and stainless steel have different densities: the density of carbon steel is slightly higher than that of ferritic and martensitic stainless steel, and slightly lower than that of austenitic stainless steel. Below we give a brief introduction for the differences between stainless steel and carbon steel in anti-corrosion resistance, appearance and price.

1. Anticorrosion and abrasion resistance

Stainless steel refers to alloys that are resistant to corrosion by weakly corrosive media such as air, steam, and water, and chemically aggressive media such as acid, alkali, and salt. And this function is mainly due to the addition of a stainless element-chromium. When the chromium content is greater than 12%, an oxide film is formed on the surface of stainless steel, commonly known as a passivation film. With this layer of oxide film, it will be difficult to dissolve in some media, and it has a good isolation effect. Strong corrosion resistance.

Carbon steel refers to an iron-carbon alloy with a carbon content of less than 2.11%, also called carbon steel. Its hardness is much higher than that of stainless steel, but it has a larger weight and lower plasticity. The typical "too rigid and easy to fold" , Easy to rust.

1. Appearance

Also, because stainless steel contains more chromium and nickel metal, the appearance color is mostly silver bright, and the surface is smooth and has a strong metallic luster. Carbon steel is mainly carbon and iron alloys, and other metal elements are relatively small. The main color of the appearance is iron, which will be much darker, and the surface is not as smooth as stainless steel.

1. Price

A large number of other alloys are mixed from stainless steel, which is more expensive than carbon steel.

The relevant introduction above is whether carbon steel is harmful to the human body and what are the differences between stainless steel and carbon steel. When decorating, it is inevitable to consider various materials. If you choose a poor material, the quality may not be reliable. Spectrum, and maintenance issues will soon arise. And some materials may be harmful to the human body, so you must judge carefully and consider them comprehensively to find products that are more suitable for your own use.
