National foreword

This British Standard has been prepared under the direction of the Aerospace Standards Policy Committee and is the English language version of

EN 2103-2:1991 “Aerospace series — Steel, nickel base and cobalt base alloy

remelting stock and castings — Technical specification — Part 2: Remelting stock”, published by the European Committee for Standardization (CEN).

EN 2103-2 was produced as a result of international discussion in which the UK took an active part

A British Standard does not purport to include all the necessary provisions of a contract Users of British Standards are responsible for their correct application

Compliance with a British Standard does not of itself confer immunity from legal obligations.

1 Scope and field of application

This standard specifies the particular requirements

for remelting stock intended to be used for the

manufacture of steel, nickel base or cobalt base alloy

castings

This standard shall be used in conjunction with

EN 2103-1

requirements

3 Manufacture

Remelting stock shall be manufactured from a melt

consisting of:

1) pure materials and added elements, or

2) pure materials, added elements plus a defined

and constant percentage of approved scrap, or

3) pure materials, added elements and approved

scrap Their proportion per melt is at the option

of the manufacturer

Unless otherwise specified on the order or

manufacturing schedule, the manufacturing

method 3) shall be applied

4 Dimensions and tolerances

The form, mass, dimensions and tolerances of

remelting stock shall be defined by agreement

between the manufacturer and purchaser

The frequency of examination adopted by the

manufacturer shall be sufficient to permit him to

certify compliance with the requirements

5 Internal defects

Remelting stock shall not contain defects prejudicial

to its intended use

Unless otherwise agreed between the manufacturer and the purchaser and stated on the order or in the inspection schedule, test methods and acceptance criteria shall be at the option of the manufacturer The frequency of examination adopted by the manufacturer shall be sufficient to permit him to certify compliance with the requirements

6 External defects

Remelting stock shall be visually examined and shall be free from corrosion, scale, slag, grease or any other foreign matter including paint, other than that approved for marking

The frequency of examination adopted by the manufacturer shall be sufficient to permit him to certify compliance with the requirements

7 Chemical composition

See EN 2103-1

8 Number of test samples

Sufficient test samples shall be provided and prepared from each batch in accordance with the requirements of EN 2103-1 for the tests required by the material standard or inspection schedule

9 Mechanical testing

Tensile test, creep rupture test, creep test required

by the material standard shall be made at a frequency of one test per batch

Tensile testing at ambient temperature shall be carried out in accordance with EN 2002-1

Tensile testing at elevated temperature shall be carried out in accordance with EN 2002-2

Creep and creep rupture testing shall be carried out

in accordance with EN 2002-5

Test results shall comply with the requirements of the material standard

10 Special tests

See EN 2103-1 For example: dross test, fracture test

11 Marking

11.1 Unless otherwise specified on the order, all

products shall bear the following identification

marking:

— material standard number,

— melt number,

— identification of the manufacturer and plant,

— such other marking as will ensure full identification

11.2 Unless otherwise specified on the order, the method of marking shall be at the option of the manufacturer provided it is not prejudicial to the alloy’s quality and the marking is permanent

11.3 The frequency of examination adopted by the manufacturer shall be sufficient to permit him to certify compliance with the requirements
