EN 10028-6:2017
(Main)Flat products made of steels for pressure purposes - Part 6: Weldable fine grain steels, quenched and tempered
General Information
- Abstract
This European Standard specifies the requirements for flat products for pressure equipment made of quenched and tempered steels as specified in Table 1.
The requirements in FprEN 10028-1:2017 also apply.
NOTE Once this European Standard is published in the EU Official Journal (OJEU) under Directive 2014/68/EU, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 2014/68/EU is limited to technical data of materials in this European Standard (Part 1 and the other relevant part of the series) and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of this specific item of equipment to verify that the ESRs of Directive 2014/68/EU are satisfied, needs to be done.

Overview
EN 10028-6:2017 - Flat products made of steels for pressure purposes, Part 6: Weldable fine grain steels, quenched and tempered is a CEN European Standard that specifies technical requirements for flat steel products used in pressure equipment. It covers quenched and tempered, weldable fine grain steels (see Table 1 in the standard) and is intended to be applied together with EN 10028-1:2017 (General requirements). The standard supports essential requirements of Directive 2014/68/EU but notes that conformity is limited to material technical data and does not substitute for design verification of specific equipment.
Key topics and technical requirements
- Scope and delivery condition
- Applies to flat products (plates) for pressure equipment supplied in the quenched and tempered condition.
- Classification and designation
- Steel grades are classified in series such as P...Q, P...QH (elevated temperature), P...QL1 and P...QL2 (low temperature properties).
- Chemical composition
- Cast analysis limits are defined in Table 1; permissible deviations for product analysis are given in Table 2.
- Mechanical properties
- Minimum strength, toughness and temperature-related requirements are specified in Tables 3–5; an option allows purchaser-specified minimum impact energy (e.g., 40 J).
- Weldability and welding data
- Annex A provides information on weldability; purchasers can request welding condition data as an option.
- Testing, sampling and inspection
- Test methods, sampling and inspection documents refer principally to EN 10028-1:2017 and EN 10204 requirements for inspection certificates.
- Marking and documentation
- Marking, inspection levels, retests, sorting and reprocessing follow the general provisions of EN 10028-1:2017.
- Regulatory note
- Annex ZA maps the relationship to Directive 2014/68/EU and explains the limits of material presumption of conformity.
Practical applications
- Material specification for manufacturers and fabricators of pressure vessels, boilers, heat exchangers, piping and storage tanks that require quenched and tempered, fine grain steels with specified mechanical and toughness properties.
- Basis for procurement, production control and quality assurance of flat steel products for pressure equipment.
- Reference for welding procedure selection, impact testing, certification and conformity assessment when designing or manufacturing pressure-retaining components.
Who should use this standard
- Pressure equipment designers and mechanical engineers
- Steel mills and plate suppliers
- Fabricators and welding engineers working on pressure components
- Quality assurance, inspection and certification bodies
- Purchasing and procurement teams specifying material for pressure applications

EN 10028-6:2017 is a standard published by the European Committee for Standardization (CEN). Its full title is "Flat products made of steels for pressure purposes - Part 6: Weldable fine grain steels, quenched and tempered". This standard covers: This European Standard specifies the requirements for flat products for pressure equipment made of quenched and tempered steels as specified in Table 1. The requirements in FprEN 10028-1:2017 also apply. NOTE Once this European Standard is published in the EU Official Journal (OJEU) under Directive 2014/68/EU, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 2014/68/EU is limited to technical data of materials in this European Standard (Part 1 and the other relevant part of the series) and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of this specific item of equipment to verify that the ESRs of Directive 2014/68/EU are satisfied, needs to be done.
