Stainless steel hollow bars

Sandvik Materials Technology now offers 100 different sizes of stainless steel hollow bar, from 32mm to 420mm outside diameter. Hollow bar material grades available include: standard stainless steel grades Sandvik Sanmac 304/304L, 316/316L and duplex grade Sandvik Sanmac SAF 2205, 316Ti (4571), while other grades and sizes available on short delivery times depending on mill quantities.
The combination of hollow bar and Sanmac stainless steel means cutting speeds and feed rates can be increased, while tool wear decreases as a result of the inclusions within the material. Sulphides and oxide inclusions improve chip breaking and reduce tool wear without affecting the material’s corrosion resistance and mechanical strength.
Further information on the company’s extensive range of hollow bar can be found in the “Sandvik Sanmac solid and hollow bar stainless steels for machining” booklet S-02909-ENG, which also provides extensive machining data.
