3241 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.
Hot rolled unalloyed structural steels for manufacture of construction equipment, machines and various machine parts, general construction plates, road and railway vehicles
- Copper content shall be minimum 0.20 %, if copper-containing steel is specified in the purchase order.
- There is no requirement for manganese content in thicknesses thinner than 20mm.
- For each reduction of 0.01 percentage point below the specified max C an increase of 0.06 percentage point above the specified max for Mn is permitted up to a max of 1.35% by heat analysis
- Deoxidation method of this products is fully-killed. Minimum aluminium to nitrogen ratio is 2:1.
- Tensile test values apply to "transverse" test pieces
Flat / Plate
Heavy plate products are obtained by rolling semi-finished products with a rectangular cross-section (slab) produced by the continuous casting method to a specific temperature, with thicknesses ranging from 6.00 to 200.00 mm and widths ranging from 1000 to 3600 mm.
Hot rolled unalloyed structural steels for manufacture of construction equipment, machines and various machine parts, general construction plates, road and railway vehicles
- For grade 3241 of thickness greater than 40mm, the min limit of silicon content is 0.15 %.
- Tensile test values apply to "transverse" test pieces
- For plate products, minimum elongation value is reduced by 2 points.
