JIS G3459 and CNS 6331 Stainless Steel Pipes

The JIS G3459 and CNS 6331 pipes manufactured by YC INOX are made of 304, 304L, and 316L enduring and reliable stainless steel materials. Users could further adjust the chemical formula based on their processing requirements, rendering the optimal pipes for their utilization. Chemical elements such as C, Si, Mn, P, S, Ni, Cr, and Mo are chemical variables for users to do further modification.

In regard to the size specifications of JIS G3459 and CNS 6331 pipes, there are choices for customers too. Users can choose the most fitting nominal diameters as well as outside diameters and nominal wall thickness according to their machining requirements. The nominal diameter, outside diameter, and nominal wall thickness are all physical variables of JIS G3459 and CNS 6331 Pipes. With different combinations of diameters and wall thickness, the corresponding features are not the same. You may find the information in this page.

Buyers may select an appropriate packaging solution for the shipment according to their budget plan. There are mainly two choices provided: Bundle and steel crate packages.
