Ingredients:
Carbon Steel: The primary material in Q195 Carbon Steel Pipe is carbon steel, which typically contains less than 0.25% carbon content, along with small amounts of manganese, silicon, sulfur, and phosphorus. The low carbon content makes it relatively soft and ductile, yet still strong enough for many structural applications.
- Carbon: Enhances hardness and strength but reduces ductility.
- Manganese: Improves strength and hardenability without impairing toughness.
- Silicon: Enhances strength and deoxidizes the steel during production.
- Sulfur and Phosphorus: Are generally considered impurities that can reduce ductility and toughness; their content is limited in Q195.
Uses:
- Structural Applications: Q195 pipes are often used for light-load structural purposes such as scaffolding, fence posts, and agricultural equipment due to their moderate strength and good formability.
- Mechanical Parts: They're utilized for manufacturing simple mechanical components where high-strength or high-pressure resistance isn't critical.
- Conduit and Tubing: For electrical conduit systems, water supply lines in non-critical applications, and gas pipelines with lower pressure requirements.
- Furniture and Decorations: In some cases, they can be used for making furniture frames and decorative elements due to their workability and aesthetic appeal when painted or finished.
In summary, Q195 Carbon Steel Pipes are cost-effective and versatile materials suitable for various applications that do not require the higher strength levels of alloy steels. They provide a balance between strength, ductility, and ease of fabrication, making them popular choices in construction, infrastructure, and general engineering sectors.
