E355 EN10305-2 Round Thin Wall Steel Tube Hydraulic Parts Using Cold Rolled

Introduction

Our E355 EN10305-2 round thin wall steel tube is precision-crafted for hydraulic systems. Made from cold-rolled steel, this tube features a thin wall thickness, precise dimensions and excellent mechanical properties. The cold rolling process ensures a smooth, even surface finish. Ideal for use in hydraulic cylinders, valves and other components that require high strength, precision and corrosion resistance.

Description

Delivery Condition

1. NBK(+N)
after cold forming, eventually above phase transition point, in a protective atmosphere of annealing oxidation medium
2. GBK(+A)
after cold forming, annealing in non oxidizing medium protective gas
3. BK(+C)
the final heat treatment after cold forming, threfore small steel pipe plasticly, the plasticly degree does not guarantee
