BS EN 10222-2:2017+A1:2021

What is BS EN 10222‑2 standard about?  

BS EN 10222‑2 specifies the technical delivery conditions for forgings for pressure purposes, made of ferritic and martensitic steels with specified elevated temperature properties. Chemical composition and mechanical properties are specified 

NOTE: Once this standard is published in the EU Official Journal (OJEU) under Directive 2014/68/EU, the presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 2014/68/EU is limited to technical data of materials in this standard 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. The series EN 10222–1 to EN 10222–5 is structured so that the data related to different materials is in the part allocated for that material. The presumption of conformity to the Essential Safety Requirements of Directive 2014/68/EU depends on both the text in part 1 and the data in part 2, 3, 4 or 5. 

Who is BS EN 10222‑2 standard for?  

BS EN 10222‑2 on steel forgings for pressure purposes is beneficial for 

• Manufacturers of forged steel  
• Manufacturers and suppliers of ferritic and martensitic steels 
• Quality engineers 
• Fabricators 
• Welders 

Why should you use BS EN 10222‑2 standard?  

Steel forging is a manufacturing process involving the shaping of metal using compressive forces, and is widely used in mechanical and industrial applications. 

BS EN 10222‑2 provides information on heat treatment, chemical composition, mechanical properties at various temperatures, stress rupture properties which assist the user to manufacture forged steel products used for pressure appliances and helps the user to understand the properties of ferritic and martensitic steels 

With BS EN 10222-2, you will be able to undergo the shaping of a permanent steel part without it cracking under high pressure and corrosive environments. As a result, it will enable you to 

provide and deliver better end-products that have high tensile and fatigue strength and long service life.  

What’s changed since the last update?  

BS EN 10222‑2:2017+A1:2021 supersedes BS EN 10222‑2:2017, which is withdrawn. 

Some significant changes done compared to the previous version are 

• Updated normative references and ordering information’s 
• Table containing values and statements on the heat treatment of the steels updated 
• New steel grade P250GH inserted in the standard 
• Updating of the values for the chemical composition and mechanical properties for the steel-grades 
• “Resistance to hydrogen-induced cracking” inserted in the standard
