1.6-40mm Alloy Seamless Steel Pipe ASTM A335 P9 Cold Rolled

ASTM A335 P9 alloy steel pipe/ASTM A355 P9 alloy seamless steel pipe

Product Description

Seamless Mechanical Tubing
The seamless tube is manufactured using a process called “extrusion”. During this process a solid steel bar is pierced though the centre using a die, turning the solid round into a round tube.

Basically there are two types of seamless tube:
Cold Drawn Seamless (CDS) and Hot Finished Seamless (HFS). Both CDS and HFS steel tubes provide strength and durability, but the process used to create each type of tubing provides slightly different advantages. Deciding whether Cold Drawn Seamless or Hot Finish Seamless is best will depend on how you plan to use the tubing for your application.


Cold Drawn Seamless mechanical tubing is created by hot rolling SAE 1018 carbon steel, then drawing it at room temperature. During the drawing process, the pointed end of the tube is passed through a die. Force is used to stretch the steel into the desired thickness and shape and smooth the surface. This type of steel tubing meets ASTM A519 standards. It provides high yield strength, close tolerances and a smooth finish that is preferable for many mechanical applications.

Hot Finished Seamless mechanical tubing is produced using SEA 1026 carbon steel and is manufactured using the same extrusion process, only without the final step of drawing the tube at room temperature. The HFS process produces a steel tube that is easily machinable and is ideal for applications where a close dimensional tolerance or smooth surface finish is not required. HFS steel tubing meets ASTM A519 standards and is commonly used for applications requiring a thicker, heavier wall.

Benefits of Cold Drawn Seamless (CDS):
Good surface finish – Superior machinability – Increased dimensional tolerances – High strength to weight ratio

Benefits of Hot Finished Seamless (HFS):
Cost effective material – Good Machinability – Wide range of sizes
