What is BS EN 10222‑3 - Nickel steel about?
BS EN 10222 is a series of European standards on steel forgings for pressure purposes that discusses the best procedures and specifications on manufacturing high-quality nickel steel forged products for the construction of safe pressure equipment.
BS EN 10222-3 is the third part of a series of documents on steel forgings for pressure purposes. BS EN 10222‑3 specifies the technical delivery conditions of forgings for pressure purposes, made of nickel steels, for use at low temperatures.
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 parts 2, 3, 4, or 5.
Who is BS EN 10222‑3 - Nickel steel for?
BS EN 10222‑3 on steel forgings for pressure purposes is relevant to:
- Manufacturer of nickel steel forge products
- Manufacturer of pressure appliances
Why should you use BS EN 10222‑3- Nickel steels?
Nickel-Steel alloy is the most important among all the steel alloys due to its use in various places all around the world. It is formed when some percentage of nickel is added to the steel. It has a content of carbon too. It contains 0.35% carbon and 3.5% nickel in its composition.
BS EN 10222‑3 navigates you through the steelmaking process and manufacture of the product, chemical composition, and chemical composition properties, mechanical properties, surface condition, internal soundness, resistance to hydrogen-induced cracking.
As a user of BS EN 10222-3, you can be ensured of all the requirements of forgings for pressure purposes, made of nickel steels. With obedience and compliance to BS EN 10222-3, you can efficiently forge high-quality nickel steel forgings with low-temperature properties for pressure purposes. With BS EN 10222-3, you will be able to undergo the shaping of a permanent nickel 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. With BS EN 10222-3 you can be ensured that the products consistently meet and exceed quality assurance targets.
