Chemical and mechanical properties of 20 # steel

Introduction to material grade of 20 # steel:
20 # is a simple way to write 20 steel, which is one of the steel materials. It is named according to the content of carbon (C) element in steel plate. Generally, the carbon content in this material is about 0.2%. This material is also more common than other superior carbon steels.

Brief analysis of chemical composition of 20 # steel:
In addition to the five major elements in steel 20, each element content has a certain range standard, which is analyzed as follows:
The average carbon content is 0.17-0.23%
The average silicon content is 0.17-0.37%
The average manganese content is 0.35-0.65%
Average sulfur content ≤ 0.035%
Average phosphorus content ≤ 0.035%
Average chromium content ≤ 0.20%
Average nickel content ≤ 0.30%
Copper content is about 0.20%.

Brief analysis of mechanical properties of 20 # steel:
The delivery status of 20 # steel can be normalized, quenched, tempered and other different delivery statuses. Hardness and yield tensile strength parameters of steel plate can be strictly executed according to corresponding standards. 20 # steel belongs to high-quality low-carbon steel, cold extruded and hardened steel. 20 # steel has low strength, good toughness, plasticity and weldability. The tensile strength is 253-500MPa, and the elongation is ≥ 24%.

Application of 20 # steel material:
20 # steel has good material performance, which is commonly used in manufacturing vehicles, cranes, mining machinery, power plant equipment and other manufacturing industries. The performance requirements for steel plates are relatively good.
