BS EN 10025-4:2019 pdf free download.,Hot rolled products of structural steels – Technical delivery conditions for thermomechanical rolled weldable fine grain structural steels.
BS EN 10025-4:2019 specifies technical delivery conditions for flat and long products of hot rolled weldable fine grain structural steels in the thermomechanical rolled condition in the grades and qualities given in Tables 1 to 3 (chemical composition) and Tables 4 to 6 (mechanical properties) in thickness ≤ 150 mm.
The steels specified in this document are especially intended for use in heavily loaded parts of welded structures such as, bridges, flood gates, storage tanks, water supply tanks, etc., for service at ambient and low temperatures.

7.2 Chemical composition
7. 2. 1 The chemical composition determined by heat analysis shall comply with the specified values of Table 1.
For elements not defined in the table for the chemical composition for heat analysis, limit values of Table 1 of EN 10020: 2000 shall apply as maximum values.
7. 2. 2 The limits applicable for the product analysis are given in Table 2. The product analysis shall be carried out when specified at the time of the order.
See Option 2, Clause 13 (product analysis).
For elements not defined in tables for the chemical composition for product analysis, limit values of Table 1 of EN 10020: 2000 shall apply as maximum values.
7. 2. 3 The maximum carbon equivalent values based on the heat analysis, given in Table 3 shall apply.
