Introduction
Hot Finished Seamless Mechanical Tubing (HFS) is a cost effective 1020/1026 carbon seamless mechanical steel tube where precise finish dimensions and surface quality are of secondary importance. It is a cost effective alternative to cold drawn with a wider tolerance range. Hot Finished Seamless mechanical tubing is manufactured to OD and wall dimensions.
- Made from 1020/1026 Steel
- Meets ASTM A519 & A106
- Stocked Size Range: 3.00" - 26.000" OD; 0.500" - 4.000" wall
- Stocked Lengths 17'-40'
- Cut to Length sizes.
Benefits of Hot Finish Seamless:
- Cost effective material
- Machinability. Excellent candidate for most processing techniques.
- Wide range of sizes
- Applications: Designed to be machined for high strength-close tolerance projects. Bushing, axles, hydraulic cylinders, hinges, rollers, spacers, and sleeves.
