    Sammanfattning : It has been found that profiles delivered to customers in unaged (T4) statehave had different hardnesses despite using the same manufacturing process.It has emerged that the material have been stored different periods oftime before use and therefore have small variations in hardness. In furtherprocessing this may lead to problems. LÄS MER
