HARD CHROME BARS
HARD CHROME BARS
AISI 1045 is a Medium Carbon Steel With a Tensile Strength in the Range 600 - 800 Mpa.
It can achieve around 55 - 62 HRC surface Hardness after Induction Hardening Process and 900 - 1100 HV at the Chrome Plated Surface.
This offers Excellent Wear Resistance, Good Corrosion Resistance and High Resistance to Surface Indentation.
Typical Applications:
High strength bearings, bushings, bolts, gears, Hydraulic and pneumatic cylinders with high surface impact resistance for mining, earth moving, machine tools, waste disposal transport, car jacks, food processing, mechanical tools, hoists and compressors etc.
Standard Size: Dia 8 to 190mm.
Standard Length: Upto 3000mm.
