◎ C-Cold rolled strip;H-Hot rolled strip;P-Hot rolled plate;T-Thickness;t-transverse;l-Longitudinal
◎ +A=annealed;+AT=solution annealed;+QT = quenched and tempered;+RA=recrystallizing annealed condition
◎ Austenitic-ferritic steels need to be tested to the impact energy requirements ensure that toughness is adequate. In contrast, Austenitic steels always have adequate toughness and do not need to be impact tested.
* Resistance to intergranular corrosion when tested according to EN ISO 3651-2. In the delivery condition: yes;In the sensitized condition: yes.
① For continuously hot-rolled products, 20N/mm² higher minimum values of Rp0,2 and 10N/mm² higher minimum values of Rp1,0 may be agreed at the time of enquiry and order.
② If, in the case of strip in rolling widths < 300 mm, longitudinal test pieces are taken, the minimum values are reduced as download:proof strength: minus 15 N/mm²,elongation for constant gauge length: minus 5 %,elongation for proportional gauge length: minus 2 %
③ T<3mm:This value applies to specimens with a gauge length of 80 mm and a width of 20 mm. Specimens with a gauge length of 50 mm and a width of 12.5 mm may also be used. T ≥3mm:This value applies to specimens with a gauge length of 5.65√S
