Import 316 Stainless Steel Cylinder — Buy in Bulk from Supplier in China

This 316 stainless steel cylinder is engineered for industrial use, with a surface roughness of 0.4 to 0.1 micrometres ensuring a smooth, precision finish for applications where tight tolerances are critical. The material grade 316 provides enhanced corrosion resistance, particularly against chlorides and marine environments, making it suitable for chemical, pharmaceutical and offshore applications. The component has undergone surface treatment to achieve a hardness of HRC60, which significantly improves its wear resistance in high-friction settings.

The cylinder meets stringent geometric tolerances, including a straightness tolerance of 0.15 per 1000 mm and circularity adhering to GB118 standards, ensuring consistent performance in pneumatic or hydraulic systems. Standard industry practice for 316 stainless steel cylinders includes typical internal finish values of Ra 0.2 to 0.8 micrometres for dynamic seals, and wall thicknesses ranging from 1.5 mm for light-duty to 6 mm for heavy-duty variants. The material’s austenitic structure offers excellent weldability and formability, with a typical tensile strength of 500 to 700 MPa in the annealed condition.

Common applications include automation equipment, fluid power systems and precision machinery where reliability under cyclic loading is essential. Buyers in automotive and aerospace sectors source these cylinders for their combination of durability and corrosion resistance in aggressive media. Packaging is typically wooden crates or reinforced cardboard for bulk shipments, with FOB or CIF terms standard for export.
