This document specifies a flame atomic absorption spectrometric method (FAAS) for the determination of nickel content in steels and cast irons.

The method is applicable to nickel contents between 0,004 % and 2,0 %.

The method can be adapted to lower or higher nickel contents by changing the test portion or the dilution process, provided the criteria in 6.2.2 and 6.2.3 are still met.

This document specifies technical delivery conditions for flat products of high yield strength alloy special steels. The grades and qualities are given in Tables 1 to 3 (chemical composition) and Tables 4 to 6 (mechanical properties) and are supplied in the quenched and tempered condition.

The steels specified in this document are applicable to hot-rolled flat products with a minimum nominal thickness of 3 mm and a maximum nominal thickness of 200 mm for grades S460, S500, S550, S620 and S690, a maximum nominal thickness of 125 mm for grades S890 and S960, in steels which, after quenching and tempering, have a specified minimum yield strength of 460 MPa to 960 MPa.

This document specifies technical delivery conditions for flat and long products of hot rolled weldable fine grain structural steels in the thermomechanical rolled condition in the grades and qualities given in Tables 1 to 3 (chemical composition) and Tables 4 to 6 (mechanical properties) in thickness ≤ 150 mm.

The steels specified in this document are especially intended for use in heavily loaded parts of welded structures such as, bridges, flood gates, storage tanks, water supply tanks, etc., for service at ambient and low temperatures.

This document specifies a flame atomic absorption spectrometric method (FAAS) for the determination of lead content in non-alloy and low alloy steels.

The method is applicable to lead contents between 0,005 % and 0,5 %.

The method can be adapted to lower or higher lead contents by changing the test portion or the dilution process, provided the criteria in 6.2.2 and 6.2.3 are still met.

This document specifies a flame atomic absorption spectrometric method (FAAS) for the determination of calcium content in non-alloy and low alloy steels.

The method is applicable to calcium contents between 0,000 4 % and 0,012 %.

The method can be adapted to higher calcium contents by changing the test portion or the dilution process, provided the criteria in 6.2.2 and 6.2.3 are still met.

This document specifies the technical delivery conditions for flat and long products as well as semi-finished products which are meant for further processing to flat and long products of hot rolled non-alloy quality steels in the grades and qualities given in Tables 1 to 5 (chemical composition) and Tables 6 to 8 (mechanical properties) in the usual delivery conditions as given in 6.3. Three engineering steels are also specified in this document (see Tables 2 and 4) (chemical composition) and Table 7 (mechanical properties). This document does not apply to structural hollow sections (see EN 10210‑1 and EN 10219‑1) and tubes.

The technical delivery conditions apply to:

—    thicknesses ≥ 3 mm and ≤ 150 mm for long products of steel grade S460JR, J0, J2, K2 and S500J0;

—    thicknesses ≤ 400 mm for flat products of qualities JR, J0, J2 and K2;

—    thicknesses ≤ 250 mm for flat and long products of all other grades and qualities.

The steels specified in this document are not intended to be heat treated except products delivered in the delivery condition +N. Stress relieving is permitted. Products delivered in +N condition can be hot formed and/or normalized after delivery (see Clause 3).

Semi-finished products which are to be converted to rolled finished products conforming to this document should be the subject of special agreement at the time of the order. The chemical composition can also be agreed at the time of the order, however the values should be within the limits of Tables 1 and 2.

For certain grades and product forms suitability for particular applications may be specified at the time of the order (see 7.4.2, 7.4.3 and Table 9).
