BS EN 10088-3 Specification

Scope

BS EN 10088-3 Specification Standard is specifies the technical delivery conditions for semi-finished products, hot or cold formed bars, rods, wire, sections and bright products of standard grades and special grades of corrosion resisting stainless steels for general purposes.
NOTE : General purposes include the use of stainless steels in contact with foodstuffs.
The general technical delivery conditions specified in EN 10021 apply in addition to the specifications of this European Standard, unless otherwise specified in this European Standard.
This European Standard does not apply to components manufactured by further processing of the product forms listed above with quality characteristics altered as a result of such further processing.

Maximum depth of acceptable discontinuities for bars, rods and sections

Conditions	Product forms	Permissible depth of discontinuities a	Max. % of delivered weight in excess of permissible depth of discontinuities
1U, 1C, 1E, 1D	Sections	To be agreed upon at the time of enquiry and order on the basis of EN 10163-3.
1U, 1C, 1E, 1D	Rounds and rod	Unless not specified otherwise at the time of enquiry and order: EN 10221 class A za2.
1Xb, 2Hb, 2Db	Rounds	- max. 0,2 mm for d ≤ 20 mm - max. 0,01 d for 20 < d ≤ 75 mm - max. 0,75 mm for d > 75 mm	1 %
	Hexagons	- max. 0,3 mm for d ≤ 15 mm - max. 0,02 d for 15 < d ≤ 63 mm	2 %
	Other bars	- max. 0,3 mm for d ≤ 15 mm - max. 0,02 d for 15 < d ≤ 63 mm	4 %
1G, 2B, 2G, 2P	Rounds	Technically defect free by manufacture.	0.2 %
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.

All appropriate precautions are to be taken to avoid the addition of such elements from scrap and other materials used in production which would impair mechanical properties and the suitability of the steel. a Maximum values unless indicated otherwise. b Particular ranges of sulfur content may provide improvement of particular properties. For machinability a controlled sulfur content of 0,015 % to 0,030 % is recommended and permitted. For weldability, a controlled sulfur content of 0,008 % to 0,030 % is recommended and permitted. For polishability, a controlled sulfur content of 0,015 % max. is recommended. c Where for special reasons, e.g. hot workability for the fabrication of seamless tubes where it is necessary to minimize the delta ferrite content, or with the aim of low magnetic permeability, the maximum Ni content may be increased by the following amounts: 0,50 % (by mass): 1.4571 1,00 % (by mass): 1.4306, 1.4406, 1.4429, 1.4436, 1.4438, 1.4541, 1.4550 1,50 % (by mass): 1.4404. *) Patented steel grade.

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.
