Tubes for valve seats in special steel

Tubes in high chromium steel (11-13%) with heat resistance, until 700°, for production of valve seats.
The range of production from outside diameter 35,0 mm.
Until to outside diameter 70,0 mm.

Allows the production of valve seat rings for motorcycles, cars, trucks and tractors.
The hardness not too high (hrc 32-35) allows to have a good workability of tubes.
The high heat resistance of the material allows the use on almost all the motors.
