Hard chrome bar

1. HARD CHROME BARS

1. AISI 1045 is a Medium Carbon Steel With a Tensile Strength in the Range of 600 – 800 Mpa.

2. It can achieve around 55 – 62 HRC surface Hardness after Induction Hardening Process and 900 – 1100 HV at the Chrome Plated Surface.
3. This offers Excellent Wear Resistance, Good Corrosion Resistance and High Resistance to Surface Indentation.
4. 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.
5. Standard Size: Dia 8 to 190mm.
6. Standard Length: Upto 3000mm

Part I. The Metallurgy of: “Alloy Selection for Elevated Temperature Application”

Introduction This is a complex subject in part due to the time dependant mechanical behaviour of metals under load at elevated temperature. At room temperature, we understand that a part is failing once it is past it’s yield point – plastic deformation is occurring. The part is completely destroyed once…

Part II. The Metallurgy of: “Alloy Selection for Elevated Temperature Application”

Malabou cast special alloys that allow for castings to be used at elevated temperature’s, in some cases in excess of 1000°C. These heat resistant casting alloys consist of predominantly of combinations of nickel, chromium and iron together with small percentages of other elements. Castings made of these high temperature alloys…
