SEAMLESS MECHANICAL STEEL TUBING
ASTM A519
Seamless mechanical tubing is manufactured from carbon and alloy steels for structural or other mechanical purposes involving machining or heat treating, where close tolerances, smooth finish, or definite physical properties are important factors.
Micro alloys are available upon request. Reduce the weight of your product while increasing your physical requirements.
Cold Drawn Seamless stocks are generally carried to OD and ID tolerances, except when the ID is less than 50 percent of the OD. The latter sizes and hot-finished seamless stocks are carried in the warehouse to OD and wall tolerances.
