Technical requirements of the EN 10221 standard for rolled product surface quality
This international standard EN 10221 regulates the criteria for assessing the surface condition of hot-rolled round bars and wire rod. The scope of the standard covers metal products with a nominal diameter ranging from 5 mm to 150 mm inclusive.
In the expert practice of EV Group China, we draw the attention of customers to the following key provisions of the document:
- By mutual agreement between the manufacturer and the consumer, the requirements of EN 10221 can be extended to rolled products with other cross-sectional shapes, including hexagonal and octagonal profiles.
- The standard is a basic one for general engineering steels. The application of these criteria to structural and tool steel grades is carried out by direct agreement between the parties when placing an order.
- It is important to note that EN 10221 does not establish standard values or maximum permissible parameters for the depth of the decarburized metal layer.
EV Group China specialists are ready to provide professional advice on selecting the surface quality class according to EN 10221, based on the specifics of your engineering tasks and the conditions of subsequent mechanical processing of the products.
