What is BS EN 10051 - Hot-rolled steels tolerances about?
BS EN 10051 gives key dimensional tolerances for hot rolled coil and sheet non-alloy and alloy steels.
Who is BS EN 10051 - Hot-rolled steels tolerances for?
This standard should be used by:
- purchasers of continuously hot-rolled uncoated plate, sheet and strip non-alloy and alloy steels
- steel manufacturers
- steel users and suppliers
- students and universities
What does BS EN 10051 - Hot-rolled steels tolerances cover?
BS EN 10051 specifies tolerances on dimensions and shape for continuously hot-rolled uncoated plate/sheet and strip with a maximum width of 2 200 mm and a maximum thickness of 25 mm of non-alloy and alloy steels. This document also applies to hot-rolled strip for cold rolling.
NOTE 1: This document does not apply to: - hot-rolled strip rolled in widths w < 600 mm (see BS EN 10048);- hot-rolled patterned steel strip and plate/sheet cut from wide strip (BS EN 10363);- uncoated or electrolytically coated cold rolled sheet and strip (see BS EN 10131);- hot-dip coated steel sheet and strip (BS EN 10143); - stainless steels.
NOTE 2: This document can also be used for steels from other standards, e.g. steels for shipbuilding.
Why should you use BS EN 10051 - Hot-rolled steels tolerances?
- BS EN 10051 standardizes dimensional requests for hot-rolled steels, streamlining communication between purchasers and steel manufacturers. It also offers a set of defined options that can be referred to by the purchaser in case they do not want the basic specification.
- This updated version of BS EN 10051 introduces reduced flatness for sheet and plate in comparison with the 2010 version and reflects what is currently possible for manufacturers to achieve in terms of the geometrical properties of products.
- BS EN 10051 ensures the quality, performance and safety of steel products.
- BS EN 10051 helps manufacturers and users comply with relevant industry regulations and specifications.
- BS EN 10051 ensures the safe use of materials.
What has changed?
BS EN 10051:2023 supersedes BS EN 10051:2010. The following technical modifications have been made:
- tolerances on flatness revised;
- a new option for only positive thickness tolerances was introduced and options moved;
- thickness tolerances for strip and sheet/plate with minimum yield strength > 960 MPa must be agreed;
- flatness measurement revised;
- change regarding the tolerances of cropped coils; and
- editorially revised.
