The main differences between low carbon steel and alloy steel are as follows:
1. The concept is different: low carbon steel is carbon steel with a carbon content of less than 0.25%. Alloy steel is the addition of other alloying elements to the steel in addition to iron and carbon.
2. Different characteristics: the annealed structure of low carbon steel is ferrite and a small amount of pearlite, its strength and hardness are lower, and its plasticity and toughness are better. Low carbon steel has good weldability. Low-carbon steel has a greater tendency to aging, both quenching aging tendency and deformation aging tendency.
According to the different added elements, alloy steel adopts appropriate processing technology to obtain special properties such as high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, and non-magnetic properties.
3. Different uses: Low carbon steel is generally rolled into angle steel, channel steel, I-beam, steel pipe, steel strip or steel plate, which is used to make various building components, containers, boxes, furnace bodies and agricultural machinery. Alloy steel can be used for spring materials, rolling bearings, measuring tool materials, corrosion-resistant, heat-resistant materials, low-temperature materials, etc.
