4238 Quality Sheet Specification
Hot rolled unalloyed structural steels for manufacture of construction equipment, machines and various machine parts, general construction plates, road and railway vehicles
AlternativesThere is no alternative to this sheet.
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.

- Suitable for galvanizing as "Category A". Category A contains Si ≤ 0.030% and Si+2.5P ≤ 0.090%.
- This quality is produced as "Mod" within the framework of the agreements made with the customer
- The maximum value for nitrogen does not apply if the chemical composition shows a minimum total aluminium content of 0.020%.
- Carbon equivalent, CEV (IIW) % = C + Mn / 6 + (Cr + Mo + V) / 5 + (Ni + Cu) / 15
