1) Elements not quoted in this table In respect of the Individual steel grakles shall not be added deliberately to the steel without the purchaser's consent, axcepllor the purpose of finishing the melt. Such elements shall in no way impair the usabiity or processability of the steel, e.g. its weldability, nor shall they affect the properties specified in this standard.

2) The symbols given in the December 1972 edition of DIN 17 440 may continue to be used during the period of validity of this standard (see table in the Explanatory notes).

3) Unless otherwise specified, P ÷ 0.045%, S ÷ 0.030%, Si ÷ 1.0%, for austenitic steels, Mn ÷ 2.0%, and for ferritic steels, Mn ÷ 1.0%.

4) Tantalum determined together with nlobium and expressed in the form of niobium content.

1) For greater wall thicknesses, the values shall be specified by agreement.

2) The vlues specified do not apply for condition f described in table 6. For this condition, they shall be agreed at the time of ordering, if required.

3) Average value from three test pieces at ambient temperature. Only one individual value of the test unit may be less than this value by a maximum of 30%.

4) When tested in accordance with DIN 50 914, G. means existing up to the limit temperatures listed in the last column of table 4.

5) Only for wall thicknesses not exceeding 6 mm.

6) Not to be used for tubes manufactured by hot working or subjected to further processing.

7) To be used for tubes manufactured by hot working or subjected to further processing.
