NOTE The delivery condition-annealed to achieve spheroidized carbides(+AC)-may be agreed. In such cases, limits on spheroidization and mechanical properties may also be agreed at the time of enquiry and order.

102Cr6 1.2067 Quenched Tempered Strip Surface finish

The surface finish of cold rolled narrow steel strip shall be bright as produced by rolling and annealing in a controlled atmosphere.

The surface finishes of quenched and tempered cold rolled strip are as follows:

1 grey/blue oxide finish:unpolished;

2 brigth tempered:unpolished

3 polished: obtained by fine grinding, abrasive brushing or other processes;

4 polished and coloured:blue or yellow colour obtained by oxidization by heat treatment.

102Cr6 1.2067 Quenched Tempered Strip Decarburization

For silicon alloyed steels, decarburization shall not exceed 3% of the material thickness per side,for non silicon alloyed steels, decarburization shall not exceed 2% of the material thickness per side when measure data distance of 5mm from the stripe edge

Hardened and Tempered Steel Strip (also known as hardened and tempered High carbon steel strip or, hardened and tempered carbon spring steel strip) is the basic raw material from which many different components are made, substantially being spring-type applications ranging from clutch plate segments to washers, retractor springs and even to tree springs in riding saddles and traditional clock springs. These strip products are a specialty of the Company and considerable plant development has taken place in recent years to facilitate a very wide range of dimensions, mechanical properties and coil weights. Hardened and Tempered Steel Strip gauges of between 0.10mm and 2.00mm can be processed and, depending on the appropriate combination to suit the process equipment, strip widths of between 4.76mm to 240mm are produced. The facilities also allow up to 2000kg coils to be produced though most are well below this, being governed by a very approximate relationship of 100kg per 25mm of width.

102Cr6 1.2067 - description and application

102Cr6 material, is a construction steel of spheroidal bearing steel grades which exhibits high hardness, abrasion resistance and relatively easy mechanical treatment. 102Cr6 is used for the production of bearings and other pressure and friction-resistant components that do not operate at elevated temperatures, and the dimensions used are limited to approximately 30mm of thickness.It should also be mentioned that 102Cr6 and the more common equivalent of 102Cr6 have a limited tendency to deformation, medium hardening capacity, and at operating temperatures up to 150 ℃ during friction the product may be tempered.Steel is used for the production of rings, ball bearings, rollers, roller bearings or discs in the form of hot-rolled tubes, round bars, thin and thick sheets, forgings, wires or wire rods. The equivalent of the 100Cr6 steel is the 102Cr6 tool steel, which in turn is the 102Cr6 material.102Cr6 as a differently graded flat or round grade is used for the manufacture of cold forming dies and stamps, file cutters, wood and paper cutting knives, taps, scrapers, or broaches.

The surface finish of Hardened and Tempered Steel Strip products is not too critical in general engineering applications where the normal blue-black (also known as blue-grey) oxidized finish from the heat treatment is satisfactory. By control of the atmospheres in the furnaces non-oxidised surfaces can also be produced, on a selected basis, and alternatively, steels can be satin or bright polished were needed, these finishes being as much for cosmetic reasons as for engineering purposes.
