Product Code:SAE MAM2243
Title:Tolerances, Metric, Corrosion and Heat Resistant Steel Tubing
Issuing Committee:Ams F Corrosion Heat Resistant Alloys Committee
Scope:This specification covers manufacturing tolerances applicable to seamless and welded tubing of corrosion and heat resistant steel ordered to metric dimensions. These tolerances apply to all conditions and are based on individual measurements, unless otherwise noted. Tubing may be specified by two dimensions only (OD and wall thickness, ID and wall thickness, or OD and ID).
