Stainless Steel Tube for Air Cylinders
Meeting ID (-0) Tolerances and Mechanical Properties
CREST CLM CLU are manufactured according to ASTM A269 with various ID tolerance requirement 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 mechanical properties such as hardness, tensile strength, 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 and 1) ID controlled (CLM, CLU), 2) OD-controlled (CLO) and 3) both ID-&OD-controlled (CLB).
