Q235B Carbon Steel Pipe Tube
Q235B Carbon Steel Pipe Tube Product Introduction:
Q235B Carbon Steel Pipe Tube is a structural steel with low carbon content, known for its excellent plasticity and weldability, making it widely used across various engineering fields. Here's an overview of its characteristics and applications:
Chemical Composition:
Q235B steel has a carbon content ranging from 0.12% to 0.20%, with silicon (Si) up to 0.30%, manganese (Mn) between 0.30% and 0.70%, and phosphorus (P) and sulfur (S) both not exceeding 0.045%.
Mechanical Properties:
It exhibits a yield strength of at least 235 MPa for steel bar diameter or plate thickness ≤ 16mm. The tensile strength ranges from 370-500 MPa, and the elongation is no less than 26% for thickness ≤ 40mm, decreasing to 21% for thickness > 150mm.
Applications:
Q235B Carbon Steel Pipe Tube is extensively used in structural engineering, such as building structures, bridges, steel frames, and pipelines, where it performs support and transportation functions.
It is also utilized in the oil and gas transportation sector for pipelines where its strength and corrosion resistance are capitalized on.
In the machinery manufacturing industry, Q235B steel plays a significant role in the production of bearings, parts, and components.
The pipe is also widely used in the coal mining and chemical industry for support, chemical equipment, and transportation purposes.
In building decoration, Q235B carbon steel pipe is employed for indoor and outdoor decoration, railings, and handrails, enhancing the aesthetic and practical aspects of construction.
