EN 10025-2 Grade S185 normalized or normalized formed (+N)

EN 10025-2 Grade S185 normalized or normalized formed (+N) introduction

The hot rolled, unalloyed quality steel S185 is applicated for not strength loaded parts that are not liable to inspection. The chemical composition is not specified.
The steel is not intended for heat treatment. Stress relieving annealing is allowed. Products in the delivery condition +N may be hot formed and/or normalized after delivery.
For long products and continuous rolled flats the delivery condition is up to the producer +AR, +N or +M. The delivery condition of four-high rolled sheet is also up to the producer and may be +AR or +N. Both conditions can be ordered.
