Thabiso Steel, located in Cape Town, South Africa, has built a solid reputation as a reliable manufacturer and supplier of high-quality steel products that adhere to international standards. One of their standout offerings is the Carbon Steel DIN 17173 Pipe, which serves as a trustworthy option for a variety of industrial and mechanical applications. Known for its strength, durability, and consistent quality, this pipe is perfect for general use in low-pressure and moderate-temperature settings. Thabiso Steel prides itself on precision manufacturing, technical support, and dependable delivery, ensuring that clients in construction, engineering, and processing sectors get the right materials to meet their operational needs.
The Carbon Steel DIN 17173 Pipe is a non-alloy steel pipe standard that’s primarily designed for low-pressure applications. It typically contains a carbon content ranging from 0.10% to 0.25%, with manganese levels up to 0.60%, along with trace amounts of silicon, phosphorus, and sulfur. These components contribute to its good formability, moderate tensile strength, and excellent weldability. The mechanical properties showcase a tensile strength between 340 and 470 MPa and a yield strength of around 235 MPa, depending on the specific grade. While DIN 17173 pipes aren’t meant for high-stress situations, they perform reliably under normal mechanical loads, making them suitable for shaping, bending, and moderate-pressure service conditions.
