S185
1.0035The cheapest and lowest-grade structural steel in EN 10025-1. Only tensile strength is guaranteed (290-510 MPa), no guaranteed yield strength, composition, or impact toughness. Used for non-critical structural applications, fences, lightweight frameworks, and temporary structures where only minimum strength is needed.
