What is BS EN 10028‑7 - Stainless steels about?
BS EN 10028 is a series of European standards on flat products made of steel for pressure purposes that discusses the best procedures and specifications on manufacturing high-quality sheets and plates from stainless steels for the construction of safe pressure equipment. BS EN 10028-7 is the seventh part of a series of documents on flat products made of steel for pressure purposes. BS EN 10028‑7 specifies requirements for flat products for pressure purposes made of stainless steels, including austenitic creep resisting steels.
NOTE 1: The steel grades covered by BS EN 10028‑7 have been selected from EN 10088–1.
NOTE 2: Once this European Standard is published in the Official Journal of the European Union (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 European Standard (Part 1 and Part 7) 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 the Pressure Equipment Directive are satisfied needs to be done.
Who is BS EN 10028‑7 - Stainless steels for?
BS EN 10028-7 on flat products made of steels for pressure purposes is relevant to:
- Manufacturer of stainless steels products
- Manufacturer of pressure appliance
Why should you use BS EN 10028‑7 - Stainless steels?
Stainless steels are steels containing at least 10.5% chromium, less than 1.2% carbon and other alloying elements. Stainless steel's corrosion resistance and mechanical properties can be further enhanced by adding other elements, such as nickel, molybdenum, titanium, niobium, manganese, etc.
BS EN 10028‑7 navigates you through the tolerances on dimensions, classification, and designation, steelmaking process, surface condition, internal soundness, chemical properties, mechanical properties, test methods.
BS EN 10028-7 exemplifies the required chemical composition and chemical corrosion properties, mechanical properties that help you achieve precision in terms of product functionality and specification.
As a user of BS EN 10028-7, you can be ensured of all the requirements for flat products made of stainless steel for pressure purposes. With obedience and compliance to BS EN 10028-7, you can efficiently manufacture high-quality corrosion-resistant flat products for pressure equipment made of stainless steel. With BS EN 10028-7 you can be ensured that the products consistently meet and exceed quality assurance targets. BS EN 10028-7 provides you with comprehensive information useful throughout the process of production.
