Hardened And Tempered Steel Strip
|
Hardening and Tempering is a thermal process that strengthens steel strips through a controlled heating and cooling process. The hardening process involves heating the steel strip to above the critical transformation temperature for the given grade and then
rapidly cooling. The steel strip in this condition is extremely brittle and requires further treatment in the tempering. Then strips are reheated to a lower temperature and holding it at the given temperature for a given period of time. This process is done in an inert atmosphere to avoid oxidation. This type of steel strip has high degree of toughness and has excellent spring properties. |

Strictly Quality Test Before Delivery
---Cgood steel well know the most import features of the hardened and tempered steel strip material, so we will test
1)hardness test
2)flatness test
3)straightness test
4)thickness test
5)width test
6)Microstructure test (according to customer's requirement)
7)Chemical composition test (according to customer's requirement)
during and after the production, so that we can make sure our material suitable for customer's requirements.
7)Chemical composition test (according to customer's requirement)
Hardness test for hardened and tempered steel strip
Cgood steel will make the hardness test during the production, so that we can keep
uniform hardness
of all materials that we produce, we will strictly control on our quality. All materials shall be measured on customer's requirement scale.
Flatness test for
hardened and tempered steel strip
The unflatness across the strip (also called cross camber and cross bow) is expressed as a percentage of the strip width. The unflatness along the strip, sometimes called coil-set, is also expressed as a percentage. Unless otherwise agreed upon the measuring length = the strip width for flatness measurements along and across the strip. Influence of possible residual stresses from slitting shall be excluded.
Tolerance Maximum permitted deviation class
P1 0.4mm
P2 0.3mm
P3 0.2mm
P4 0.1mm
Straightness test for hardened and tempered steel strip
Straightness deviation is specified in millimeters and defined as lateral deviation of the edge from a straight line as shown in
the graphic. The straightness deviation is stated as edge camber(bow) and measured over a strip length of 1 or 3 meters. Straightness tolerance depends on the strip width and is given as one of five straightness classification groups (R).
