1045 hard chrome plated bar is used extensively by the hydraulic and pneumatic industries, and is employed by other industry sectors for a wide range of applications.1045 is a medium tensile carbon steel supplied in the cold drawn or turned, precision ground, polished, chrome plated and final polished condition, with a typical base metal tensile strength of 670 – 800 Mpa, plus a typical hard chrome plated surface hardness of HV 1000 – 1150. Characterized by an extremely smooth surface finish with excellent wear and corrosion resistance, coupled with a base material giving good strength and impact properties, plus good machinability and reasonable weldability.
Typical applications are: Agricultural Equipment, Compressors, Car Jacks and other Transport Lifting equipment, Food Processing Equipment, Hoists, Mining and other Earth Moving Equipment, Machine Tools, Mechanical Tools and Equipment, Rods and Shafts (Various), Waste Disposal Transport and Equipment etc.
Machining
1045 hard chrome plated bar has very good machinability, similar to 1045 uncoated bar. Machining however should commence beneath the chrome plating, or at the unchromed surface at the end of the bar. To protect the polished chrome surface, soft materials such as copper, aluminium or mild steel should be used as clamping materials and any particles of hard chrome should be removed immediately to avoid scratching. Otherwise all machining operations may be carried out satisfactorily.
Welding
1045 hard chrome plated bar is readily weldable (similar to 1045 uncoated bar) providing the correct procedure is employed. The cardboard tube protecting the chrome plating should first be removed from the heat affected area otherwise it can cause some corrosion of the plating due to fumes emitted.
