Precision ID Tolerances & Superior Mechanical Properties

Stainless Steel Tube for Air Cylinders

CREST CL is manufactured according to ASTM A269 with ID & OD tolerances of H8, H9, H10 and H11 with the specific purpose of servicing pneumatic cylinder industries.  In order to insure perfect ovality, surface finish and the target values for hardness, tensile and yield strength and elongation, the mother tube is precision cold-drawn in multiple stages.  Stainless steel pneumatic cylinder bores are offered in either imperial or ISO metric sizes.
