Scope

BS EN 10088-3 Specification Standard – Adfast Component LTD

Adfast Component LTD offers products compliant with BS EN 10088-3, which specifies technical delivery conditions for semi-finished products, hot or cold-formed bars, rods, wire, sections, and bright products of corrosion-resistant stainless steels. These materials are suitable for general purposes, including applications involving food contact.

Our products meet the general technical delivery conditions of EN 10021, ensuring high-quality standards. However, this standard does not cover components altered by further processing. Choose Adfast Component LTD for reliable stainless steel solutions.

a Depth of discontinuities is understood as being the distance, measured normally to the surface, between the bottom of the discontinuities and that surface. b At the time of enquiry and order it may be agreed that the product shall be delivered with a surface being technically defect free by manufacture. In this case, also the maximum % of delivered weight in excess of permissible depth of discontinuities shall be agreed.

Tensile test at elevated temperature	o	To be agreed at the time of ordering (see Tables 20 to 24)	1
Impact test at ambient temperature	o	To be agreed at the time of ordering (see Tables 8 to 17)	3
Resistance to intergranular corrosion	o	To be agreed at the time of ordering if intergranular corrosion is a hazard (see Tables 8, 9 and 10)	1
a Tests marked with an “m” (mandatory) shall be carried out as specific tests in all cases. Those marked with an “o” (optional) shall be carried out as specific tests only if agreed at the time of ordering. b Product analysis may be agreed at the time of ordering; the extent of testing shall be specified at the same time. c Each batch consists of products coming from the same cast. The products shall have been subject to the same heat treatment cycle in the same furnace. In the case of a continuous furnace or in process annealing a batch is the lot heat treated without intermission with the same process parameters. The shape and size of the cross sectional area of products in a single batch may be different providing that the ratio of the largest to the smallest cross sectional areas shall be equal or less than three.
