Footnotes
1) Semi-finished products available from stock see SN 483 (Standards Book, Chapter 9).
2) The notch impact energy values are determined at 20C (for S355J2G3 at 20C) and are valid for samples withlongitudinal fibre orientation.
3) Measured on polished round bars of 10 mm dia.
4) The hardening depth (Eht) depends upon the duration of use. Therefore, only the absolutely necessary Eht has to beindicated for reasons of economy.
5) Categories of suitability for welding:
Category 1: Well-suited for welding.
Category 2: In general well-suited for welding, heat pre- and/or post-treatment may be required.
Category 3: Moderately suited for welding, preheating and tempering required after welding.
Category 4: Limited suitability for welding. Moderately suited for welding, preheating and tempering required afterwelding; special electrode must be used.
Category 5: Difficult to weld or no suitability for welding.
6) The specified temperatures are guidance values; for the exact determination of the preheat temperature the influencesexerted by electrode thickness, plate thickness and type of weld must be taken into account. If necessary, thedepartment of welded fabrications must be consulted.
7) In the case of steel the relative cost refers to S355J2G3 (St 52-3), in the case of cast iron EN-GJL (GG) and EN-GJS(GGG) to EN-GJL-2900 (GG-20), and in the case of cast steel to GS-38 (GS-38). Comparisons are possible only withinthe individual groups of steel, cast iron or cast steel. The data on relative cost must not be used for cost estimating. Inthe case of cast iron and cast steel the relative cost does not include the cost of the wage, mould and core components,which lead to a higher relative cost depending upon the degree of difficulty in the making of the castings.
8) There are difficulties in the supply of hot-rolled pipe St 37.4, for this reason St 35.8 (boiler pipe) has to be used, whichincludes St 37.4 in terms of quality.
9) NBK = normalised (former designation system) + (bright annealed, after the last cold working the pipes have beenannealed in a shielding gas atmosphere at a temperature above the upper transformation point).
10) The materials of DIN 17212 are steels specially developed for flame and induction hardening, which are not alwaysavailable from stock; in this case the corresponding C-steels of DIN EN 10083 can be used as substitutes. These steelsare not always fine-grained, there may be an increased risk of failure.
11) For workpieces with thicknesses above 30 mm the hardness values are lower.
12) The steel is available in two strength categories and the drawing must bear an indication like e.g. "Quenched andtempered to 700-850 N/mm".
13) When used for castings for hydraulic components, the drawing must state: Casting for hydraulic components, testpressure e.g. 300 bar.
14) Entries concerning heat treatment after casting are not required in addition to the material designation itself.
15) Entry required for weld-in parts: Product analysis C 0,25 %.
15) Wrought alloy
16) Bushings in sintered bronze B 50 are standardised up to d1= 80 mm and commercially available up to d1= 100 mm.To be used only up to an operating temperature of 80 C. In the case of bigger diameters and temperatures above80 C, "DEVA metal" or "devagleit" must be used instead.
18) Upon agreement
19) Observe DIN EN 10164 when loading is in thickness direction (lamellar tearing).
20) The desired heat-treatment condition in the as-delivered state is indicated by additional symbols preceded by a plus sign(e.g. 13CrMo4-5+NT) after the material designation.
21) The material designation already indicates the heat-treatment condition upon delivery.

At least one of the grain-minimizing elements, one of which is aluminium, should be present at a min. percentage of 0,015%.In the case of aluminium the minimum of 0,015% is valid for the soluble aluminium; this value is also considered attained when the total aluminium contentis at least 0,018%; in cases of arbitration the content of soluble aluminium must be determined.
