EN 10132-4 is the European Standard for cold rolled narrow steel strip for heat treatment. These grades are commonly used in the production of springs, washers, circlips, hand tools, blades etc.
Typically after pressing and forming in the annealed condition, the components are then heat treated to achieve the required hardness and tensile strengths.
Details of the chemistry and mechanical proerties in the supplied condition can be found here.
Whilst lead times within Europe are commonly extending in to 2008 for these products, we are (at the time of writing), able to offer deliveries within October.
