BS EN 10025-3:2019 pdf free.Hot rolled products of structural steels.
7.3.1.1 Under the inspection and testing conditions, as specified in Clauses8, 9 and 10, and in the .delivery condition, as specified in 6.3,as well as after normalizing heat treatment after delivery (including delayed cooling or tempering if needed for steels with a minimum yield strength 2 420 MPa) the mechanical properties shall comply with the values given in Tables 4 to 6. Stress relieving at more than 580°C or for over 1 h can lead to a deterioration of the mechanical properties of the steel grades. For flat products the maximum stress relief temperature should be 560 °C. If the purchaser intends to stress relief the products at higher temperatures or for longer times than mentioned above the minimum values of the mechanical properties after such a treatment should be agreed upon at the time of the order. 7.3.1.2 . For flat and bar products ordered and supplied in the normalized or normalized rolled condition the mechanical properties shall comply with the relevant tables for mechanical properties in the normalized or normalized rolled condition or after normalizing by heat treatment after delivery or after hot forming if the provisions of CEN/TR 10347 are satisfied.7.3.2.2  Another temperature (given in Tables 5 and 6) may be agreed upon at the time of the order. See Option 24, Clause 13 (Agreement on another impact test temperature). 7.3.2.3 If agreed upon at the time of the order the impact properties shall be verified on transverse V-notch test pieces instead of longitudinal test pieces with minimum values as given in Table 6. See Option 30, Clause 13 (lmpact properties verified on transverse test pieces). 7.3.2.4 If specified at the time of the order for flat products out of each parent plate or coil the impact properties only or the impact properties and the tensile properties shall be verified. See Option 13, Clause 13 (For flat products on each parent plate or coil impact properties only to be verified). See Option 14, Clause 13 (For flat products on each parent plate or coil impact and tensile properties to be verified).  7.3.3 Improved deformation properties perpendicular to the surface If agreed upon at the time of the order flat and long products shall comply with one of the requirements ; specified in EN 10164. See Option 4, Clause 13 (Deformation properties perpendicular to the surface).BS EN 10025-3 pdf download.
