Applicability and limitations
DIN EN 10025-2:2019-10 adopts EN 10025-2:2019 (EN 10025-2-2019); See the data basis for the actual composition source file and table number. EN10025-2:2019 European main text, sourced from SFS-EN10025-2:2019 official English adopted standard; Tables 1/5 and 7.2, heat analysis wt%. ; Elements not listed in the table shall refer to Table 1 of EN10020:2000 per Clause 7.2.1 as maximum values, with product table values taking priority; This reference shall not be additionally multiplied by a classification coefficient of 70%. ; Form, thickness, and Cu ordering conditions must be selected; For long products/sections, the P and S limits are .005 above the table values.. C for sections >100mm must be agreed upon by contract; no automatic application range has been generated. ; Table 1 Note e/Option 27: Increased S for long products requires agreement, sulfide shape control, and Ca≥.0020; This special selection has not yet been provided; by default, it is not automatically relaxed. ; Table 1 Note f: The N upper limit may not apply when total Al≥.020, acid-soluble Al≥.015, or other sufficient nitrogen-fixing elements are present; this must be noted in the inspection certificate; The nitrogen-fixing exception requires separate confirmation that the original conditions are met.. ; Option 20 applies only to S235/S275/S355, with heat analysis Cu .25–.40 and Table 5 CEV+.02; Product analysis Cu .20–.45 shall be verified separately and not mixed into the heat analysis range. ; Option 5 for galvanizing composition involves mutual agreement, Si/P linkage, and EN ISO14713-2:2009; it is not a default option for this instance; The CEV increase in 7.2.5 is not superimposed on the default range. ; The IIW carbon equivalent is a coupled constraint. An envelope calculated from independent element extrema may exceed the standard CEV upper limit and must not be treated as a permissible actual composition combination.. ; For hot-rolled structural steels, applicability for cold-drawn/cold-bent orders does not equal applicability for cold-heading; Mechanical properties and supply shall be verified separately. ; Other elements not listed separately in EN10020 (excluding C/P/S/N) and each lanthanide element have a maximum of .10%; the fact that elements are not exhaustively listed does not imply that arbitrary additions are permitted.

Applicability and limitations
EN10025-2:2019 European main text, sourced from SFS-EN10025-2:2019 official English adopted standard; Tables 1/5 and 7.2, heat analysis wt%. ; Elements not listed in the table shall refer to Table 1 of EN10020:2000 per Clause 7.2.1 as maximum values, with product table values taking priority; This reference shall not be additionally multiplied by a classification coefficient of 70%. ; Form, thickness, and Cu ordering conditions must be selected; For long products/sections, the P and S limits are .005 above the table values.. C for sections >100mm must be agreed upon by contract; no automatic application range has been generated. ; Table 1 Note e/Option 27: Increased S for long products requires agreement, sulfide shape control, and Ca≥.0020; This special selection has not yet been provided; by default, it is not automatically relaxed. ; Table 1 Note f: The N upper limit may not apply when total Al≥.020, acid-soluble Al≥.015, or other sufficient nitrogen-fixing elements are present; this must be noted in the inspection certificate; The nitrogen-fixing exception requires separate confirmation that the original conditions are met.. ; Option 20 applies only to S235/S275/S355, with heat analysis Cu .25–.40 and Table 5 CEV+.02; Product analysis Cu .20–.45 shall be verified separately and not mixed into the heat analysis range. ; Option 5 for galvanizing composition involves mutual agreement, Si/P linkage, and EN ISO14713-2:2009; it is not a default option for this instance; The CEV increase in 7.2.5 is not superimposed on the default range. ; The IIW carbon equivalent is a coupled constraint. An envelope calculated from independent element extrema may exceed the standard CEV upper limit and must not be treated as a permissible actual composition combination.. ; For hot-rolled structural steels, applicability for cold-drawn/cold-bent orders does not equal applicability for cold-heading; Mechanical properties and supply shall be verified separately. ; Other elements not listed separately in EN10020 (excluding C/P/S/N) and each lanthanide element have a maximum of .10%; the fact that elements are not exhaustively listed does not imply that arbitrary additions are permitted.

Applicability and limitations
EN10025-2:2019 European main text, sourced from SFS-EN10025-2:2019 official English adopted standard; Tables 1/5 and 7.2, heat analysis wt%. ; Elements not listed in the table shall refer to Table 1 of EN10020:2000 per Clause 7.2.1 as maximum values, with product table values taking priority; This reference shall not be additionally multiplied by a classification coefficient of 70%. ; Form, thickness, and Cu ordering conditions must be selected; For long products/sections, the P and S limits are .005 above the table values.. C for sections >100mm must be agreed upon by contract; no automatic application range has been generated. ; Table 1 Note e/Option 27: Increased S for long products requires agreement, sulfide shape control, and Ca≥.0020; This special selection has not yet been provided; by default, it is not automatically relaxed. ; Table 1 Note f: The N upper limit may not apply when total Al≥.020, acid-soluble Al≥.015, or other sufficient nitrogen-fixing elements are present; this must be noted in the inspection certificate; The nitrogen-fixing exception requires separate confirmation that the original conditions are met.. ; Option 20 applies only to S235/S275/S355, with heat analysis Cu .25–.40 and Table 5 CEV+.02; Product analysis Cu .20–.45 shall be verified separately and not mixed into the heat analysis range. ; Option 5 for galvanizing composition involves mutual agreement, Si/P linkage, and EN ISO14713-2:2009; it is not a default option for this instance; The CEV increase in 7.2.5 is not superimposed on the default range. ; The IIW carbon equivalent is a coupled constraint. An envelope calculated from independent element extrema may exceed the standard CEV upper limit and must not be treated as a permissible actual composition combination.. ; For hot-rolled structural steels, applicability for cold-drawn/cold-bent orders does not equal applicability for cold-heading; Mechanical properties and supply shall be verified separately. ; Other elements not listed separately in EN10020 (excluding C/P/S/N) and each lanthanide element have a maximum of .10%; the fact that elements are not exhaustively listed does not imply that arbitrary additions are permitted.

Manufacturer typical single values are composition references only; no range estimate is made. They are neither standard guarantees nor measured heat results; Formula applicability requires review against the intended use and process.

Applicability and limitations

The original header does not explicitly state units; interpreted using the manufacturer’s mass-fraction % information. Neither standard guaranteed values nor measured heat analysis. Excluded from limit-based reverse search and carbon-equivalent calculation; blanks and element names alone in the other-elements field are not filled with 0. Manufacturer code: 1412.
