Here are some main characteristics of Q195 steel:
Strength
Q195 steel has a low yield strength of around 195 MPa and tensile strengths ranging from 315 to 430 MPa. While it is not called high-strength steel, it is strong enough for many structural and general-purpose applications.
Ductility
Q195 steel has good ductility, which allows it to be easily shaped, bent, or stretched without fracture. This feature makes it appropriate for a variety of fabrication methods, including cold forming, rolling, and drawing.
Hardness
Q195 steel is typically low to medium in hardness, making it easy to mill and deal with. If required, heat treatment can be used to increase hardness.
Weldability
Q195 steel is noted for its high weldability. It is easily welded with standard processes such as arc welding, gas welding, and resistance welding, making it suitable for attaching structures or components.
Machinability
Q195 steel has strong machinability, enabling for efficient machining operations including turning, milling, and drilling. It can be simply cut and fashioned into the desired shapes.
Corrosion Resistance
Q195 steel has limited corrosion resistance and is prone to rusting when exposed to moisture or corrosives. For optimal corrosion prevention, a proper surface treatment or coating is recommended.
Electrical and thermal conductivity
Q195 steel has a moderately high electrical and thermal conductivity, making it appropriate for several electrical and heat transfer applications.
