BS EN 10250‑4 is the fourth part of the EN 10250 multi-series. BS EN 10250‑4 specifies the technical delivery requirements for open die forgings, forged bars and products pre-forged and finished in ring rolling mills, manufactured from stainless steels with ferritic, martensitic, austenitic and austenitic-ferritic structures.
NOTE: The majority of steels listed in this part of EN 10250 are identical to steels specified EN 10088-3 and EN 10028-7, and more extensive information on properties is given in these European Standards.
BS EN 10250‑4 on steel forgings is relevant to:
Besides shaping the metal, open die forging of steel is vital in increasing strength and reducing porosity, thereby improving performance and functionality.
BS EN 10250‑4 provides information on chemical composition, cast analysis, product analysis, heat treatment, mechanical properties, varied temperature properties, required to conduct open die steel forging.
BS EN 10250-4 covers steel grades and their respective minimum and maximum levels of chemical composition of silicon, manganese, phosphorus and sulfur, amongst others.
BS EN 10250-4 provides guidelines on the temperatures for hot forming and heat treatment.
The information provided by BS EN 10250‑4 guides you with standardized open die steel forgings process with accuracy and precision based on the specific need of the application.
BS EN 10250‑4:2021 supersedes BS EN 10250‑4:2000, which is withdrawn
In comparison with the previous edition, the following technical modifications have been made:
