ASTM B550M ZR705 Round Zirconium Bar Machining Shafts Use

ASTM B550M ZR705 Zirconium Round Bar For Machining Shafts

Zirconium Round Bar  is an active metal, and an oxide film is formed at room temperature. This oxide film makes zirconium and its alloys have excellent corrosion resistance. At the same time, zirconium has good mechanical and heat transfer properties, coupled with significant cost advantages, making it an excellent corrosion-resistant structural material in today's petrochemical industry.
