Shalan Steel, based in Kuala Lumpur, Malaysia, is a trusted manufacturer and supplier of structural-grade carbon steel products that are built to handle the tough demands of construction, engineering, and industrial applications. With a strong commitment to international standards and quality control, Shalan Steel offers high-performance materials like the Carbon Steel DIN 17121 Pipe, which meets German specifications for structural seamless circular tubes. Renowned for its strength, formability, and versatility, this product is a go-to choice for structural and mechanical applications throughout Malaysia and Southeast Asia.
The Carbon Steel DIN 17121 Pipe is produced in accordance with the DIN 17121 standard, which outlines the requirements for hot-rolled seamless circular tubes made from non-alloy structural steels. Common grades include St37-2, St44-2, and St52-3, with carbon content typically between 0.17% and 0.22%, and manganese content reaching up to 1.60%, depending on the specific grade. The mechanical properties vary by grade, with tensile strength ranging from 340 MPa to over 510 MPa and yield strength from 235 MPa to 355 MPa. These pipes are known for their good weldability and can be easily formed, bent, and machined, making them perfect for structural applications that demand durability and reliability.
