TS EN 2206

TS EN 2206 defines a specific aerospace steel grade and its bar product condition: FE-PL1502 (25CrMo4), with a tensile strength range of 650 MPa to 850 MPa, in bars with De not exceeding 150 mm. The standard ties together material designation, mechanical strength band, and product form so the same steel is identified consistently across aerospace procurement and production.

Material designation and strength range

25CrMo4 is a chromium-molybdenum steel grade. In general technical terms, that alloying combination is widely used where a balance of strength, hardenability, and toughness is needed after heat treatment. Rm denotes tensile strength, and the specified range shows that this standard is not about any generic 25CrMo4 product, but about a narrower property class intended for aerospace use. In practice, these property windows matter because downstream forming, machining, and heat treatment depend on predictable material response.

Bar form and application context

The covered product form is bar stock, limited to De 150 mm or less, which focuses the document on a defined size class rather than on all possible stock dimensions. In general manufacturing, bars are common starting materials for machined parts and semi-finished aerospace components, where geometry, cleanliness, and mechanical condition influence the final part quality. Here, the designation, strength band, and size limit work together as a controlled material description rather than a general-purpose steel specification.

This listing represents the EN 2206-based aerospace series standard. Conceptually, it serves as a common technical language for specifying a steel product family, helping align drawings, purchasing descriptions, and quality records around the same material identity.
