Combination of materials
Bolt materials can be combined with flange material groups as given in Table 1. This table is valid for all flanges for which pressure temperature (p/T) ratings are given in prEN 1092-1. For flanges which have no p/T ratings (e.g. DN 700 and above), the tables may be used as a guide. All bolt materials can be used in the range of the p/T ratings given for the flanges. Restrictions due to the classification shall be observed (see clause 4). WARNING Bold materials 4.6 and 6.8 are not intended for the use in the scope of the Pressure Equipment Directive.

Classification of bolt materials
The classification of bolt materials as given in Table 1 is based on the comparison of the strengths of the flange material and the bolt material. The strength ratio r of the flange/bolt combination chosen is compared with the strength ratio of the flange bolt combination used for the standard flange calculation (see annex A). For each flange material group the classification is done in three strength levels:
Low strength: The strength ratio of the chosen flange/bolt combination is less than that used in the standard flange calculation. These bolts may be used for less severe service, e.g. for water service or in case of oversized flanged joints. For definition of these service conditions, special experience is necessary otherwise a recalculation of the flanged joint shall be done.
Normal strength: The strength ratio of the chosen flange/bolt combination is similar (within defined limits) to that used in the standard flange calculation. These bolts may be used for all service in the range of the P/T-ratings unless there are other restrictions to the contrary.
High strength: The strength ratio of the chosen flange/bolt combination is much more higher than that used in the standard flange calculation. These bolts may be used in the same range like normal strength level bolting. During assembly however, care should be taken not to overstress the flanges (e. g. by means of torque control).

Annex A (informative) Basic information This annex describes the rules under which the tables of this standard have been developed.
A.1 Definitions
Flange calculation model: PN designated steel flanges, for which p/t ratings are given (see prEN 1092-1) have been calculated at ambient temperature with a flange material yield stress of 225 N/mm² and a bolt material yield stress of 300 N/mm². This is the calculation model for the flanges.
Classification: Bolt materials are set in relation to flange material groups and classified on the basis of their strength. Starting from the flange calculation model classification of the bolt material is done as given in this annex A. (See also prEN 1092-1 annex F: Determination of p/T ratings for flanges using EN materials.)
r: stress ratio for classification of the bolt material (see also clause 4)
r min: minimum value of all stress ratios of one flange material to one bolt material calculated over all temperatures.
r 20: stress ratio at 20 °C of one flange material to one bolt material.
A.2 Combination of flange and bolt materials From each flange material group (e.g. group 3E0) the material with the lowest stress at 20 °C has been selected for the calculations of this group (Cast stainless steel has not been used, as the stress values are too low). The p/T ratings of the flanges itself has been calculated with the lowest value of a material group. This material is combined with each bolt material given in EN 1515-1 and the stress ratio r is calculated for all temperatures. The results are evaluated for the classification of the bolt material.

A.4 Classification The bolt materials combined with a flange material group are classified in low – normal – high strength (see also clause 4). The minimum value of r (r min) and the value at 20 °C (r 20) of one flange material to one bolt material calculated over all temperatures is used for the classification (e.g. flange material group 3E0 compared with bolt material 5.6 and temperatures from 20 °C to 300 °C). Stress ratio r below 1 means: Stress ratio r above 1 means:
Bolts are weaker than calculation model Bolts are stronger than calculation model
Classification has been done according to the following criteria:
18
Low strength: Normal strength: High strength:
for bolt materials with r min 0,9; for bolt materials with r min 0,9 & r 20 < 2; for bolt materials with r 20 2.
