What is the process of hard chrome plating?

Image
  Hard chrome plating   is a process in which a layer of chromium is applied to a surface to improve corrosion and abrasion resistance, reduce friction, and extend the life of parts used in extreme wear conditions. Hard chrome plating demonstrates excellent hardness and lubricity, and is the premier engineering choice to reduce friction, minimize wear and prevent galling. These characteristics are applicable for critical engineering applications, including: machine tool cutting surfaces, cylinder bores, strut rods, crankshafts and  hydraulic shafts . Hard chrome is also applied to molds because of its low surface energy and resultant release properties. Chem Processing can hard chrome plate steel, aluminum, or copper materials, as well as many exotic alloys. Hydraulic cylinder rods , bearing fits and seal areas frequently get damaged and worn from heavy use. When no longer functional, a part can be hard chrome plated and polished or ground back to OEM Spec. This process c...

WHAT IS THE DIFFERENCE BETWEEN 4130 AND 4340

 4130 steel, as low alloy steel, contains high amounts of chromium and is often referred to as chromoly. 4130 steel has good machinability, ductility, weldability and strength characteristics. 4130 steel is used for many different industries including the automotive, aerospace , hydraulic cylinder rod , cylidner barrel and machining industries. 4340 steel, as nickel-chromium-molybdenum alloy steel, is a very high strength steel. It is sought after for its toughness and for being used as a steel that will be highly stressed. 4340 steels are used in a variety of industries for different applications including the automotive, aerospace, and tooling industries. Chemical Composition Comparison: 4130 vs 4340 steel Standard Grade C Mn P S Si Cr Mo Ni ASTM A29 4340 0.38-0.43 0.60-0.80 0.035 0.040 0.15-0.35 0.70-0.90 0.20-0.30 1.65-2.00 4130 0.28-0.33 0.40-0.60 0.035 0.040 0.15-0.35 0.80-1.10 0.15-0.25 Mechanical Properties: 4130 vs 4340 steel Below are the mechanical properties for b...

WHAT IS DEAD ROLLER SHAFT AND LIVE ROLLER SHAFT

 live shaft and dead shaft rollers can be used for the same application and the choice is a function of the machine’s mounting system. But at other times, the differences between the two designs mandate a clear choice.  DEAD  ROLLER  SHAFT S: Roller design is bearings pressed into the ends of a hollow tube (the roller body) with a long shaft running through the bearings and extending out the ends of the rollers. The roller is considered to be a “dead shaft” because the shaft does not turn. The shaft is fixed to the machine or frames mounting system by clamping or bolting and the roller body turns about the shaft via the bearings. Roller shells can be steel, aluminum, or carbon fiber and many times are thin-walled, making them ideal for light load and high-speed web applications. Commonly used as idler rollers due to light-weight, low-turning inertia and the availability of low friction bearings which reduce roller drag. Roller rods  must be web or nip driven bec...
