6050 Quality Sheet Specification
High-strength structural steels for manufacture of any kind of machines and machine parts, general construction, road and railway vehicles
Reproducible Letter Symbols --> HRUKK --> KRKK --> L --> LKK --> LRKK --> RKK
Flat / Hot Rolled
Flat steel products are obtained by heating semi-finished products with a rectangular cross-section (slab), which are produced by the continuous casting method, to a specific temperature and then rolling them, with thicknesses ranging from 1.40 to 25.40 mm and widths ranging from 700 to 2025 mm, produceed as coil or by cutting/slit-coiling flat steel products from coils.

- Tensile test values apply to "transverse" test pieces
- Impact test is not carried out for thickness thinner than 6 mm.
- Produced by normalizing or rolling equivalent to normalizing, and mechanical values after normalizing are guaranteed.
- The values are applicable for bend angles ≤90o
