JIS G3445 STKM13C Carbon Steel Tube, STKM13C tube Supplier, STKM 13C Carbon Steel Seamless Tubes, STKM13C Equivalent Material, STKM13C Chemical Composition, JIS G3445 Equivalent Material.
Solitaire Steel is a reputable supplier of JIS G 3445 Grade STKM 13C tubes in India. These honing steel pipes are crafted through cold drawing or hot rolling, ensuring they meet high precision standards. They are commonly used to manufacture pneumatic and hydraulic components, such as cylinders. One of their key features is their seamless construction, which prevents leaks under high pressure and maintains accuracy. Additionally, these tubes exhibit high-quality finishes, resist deformation during cold bending, and show no flaring or cracks when flattened.
The composition of stkm13c tubes includes carbon, silicon, manganese, sulfur, phosphorus, and chromium. This combination results in steel pipes with excellent precision and a smooth finish. Notably, there is no oxide coating on the inner and outer walls, enhancing their durability and performance.
Known as mild steel pipes, JIS G 3445 Grade stkm13c tube are affordable low-carbon steel tubes with a maximum carbon content of 0.25%. They are easy to shape and form, making them suitable for various applications. Manufactured according to JIS specifications, these tubes are often used in hydraulic systems’ oil circuits and as precision steel pipes for automobiles, allowing for bends at any angle without losing their integrity.
