  • a Elements not quoted in this table shall not be intentionally added to the steel without the agreement of the purchaser, other than for the purpose of finishing the heat. All reasonable precautions shall be taken to prevent the addition of such elements from scrap or other material used in the manufacture which affect the hardenability, mechanical properties and applicability.
  • b Where requirements are made on hardenability of special steels (see Tables 5 to 7), slight deviations from the limits for the cast analysis are permissible, except for the elements carbon (see footnote d), phosphorus and sulphur; the deviations shall not exceed the specifications of Table 4.
  • c Steels with improved machinability as a result of the addition of higher sulphur contents up to around 0,10% S (including resulphurized steels with controlled inclusion content (e.g. Ca-treatment)) may be supplied upon request. In this case, the upper limit for the manganese content may be increased by 0,15 %.
  • d If special steels are ordered without hardenability requirements (symbols +H, +HH, +HL) or without mechanical property requirements in the quenched and tempered or normalized condition, a restriction in the carbon range to 0,05 % and/or the total sum of the elements Cr, Mo and Ni to £ 0,45 % may be agreed at the time of ordering.
  • e If agreed at the time of enquiry and order, for flat products, sulphur is restricted to maximum 0,010 % by mass.

  • a ± means that in one cast, the deviation may occur over the upper value or under the lower value of the specified range in Table 3, but not both at the same time.
  • b For steels with a specified sulphur range (0,020% to 0,040% according to cast analysis) the permissible deviation is ± 0,005%.

DIN 10083 Bolting Components Marking

Product Shall be Marked with our manufacturing trade mark "TorqBolt" or "TB" along with the designated Grade.
Grade and manufacturer’s identification symbols shall be applied to one end of studs and to the heads of bolts and screws of all sizes. (If the available area is inadequate, the grade symbol may be marked on one end and the manufacturer’s identification symbol marked on the other end.) For bolts and screws smaller than 1⁄4 in. [6 mm] in diameter and studs smaller than 3⁄8 in. [10 mm] in diameter and for 1⁄4 in. [6 mm] in diameter studs requiring more than a total of three symbols, the marking shall be a matter of agreement between the purchaser and the manufacturer.
