Indian Standard SPECIFICATION FOR FERRO VANADIUM

( Third Revision )

0. FOREWORD

0.1 This Indian Standard (Third Revision ) was adopted by the Indian Standards Institution on 24 September 1985, after the draft finalized by the Ferro Alloys Sectional Committee had been approved by the Structural and Metals Division Council.

0.2 This standard was first issued in 1960 and subsequently revised in 1969 and 1972. While reviewing this standard in view of experience gained during these years, the following main modifications have been made in this revision.

a) Inclusion of the definition of ferro vanadium,

b) Provision for range of particle size, and

c) Narrow range for vanadium has been specified for all grades.

0.3 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accord- ance with IS : 2-1960*. The number of significant places retained in the rounded off value should be same as that of the specified value in this standard.

1. SCOPE

1.1 This standard covers the requirements for two grades of ferro vanadium commonly used in the iron and steel industry.

2. DEFINITION

2.1 Ferro Vanadium - An alloy of iron and vanadium obtained by reduction and commonly used as vanadium alloying additive material in the manufacture of vanadium bearing alloy steels.

*Rules for rounding off numerical values ( r&et+ ).

3. GRADES

3.1 Ferro vanadium shall be of two grades each having three subgrades as specified in Table 1.

4. SUPPLY OF MATERIAL

4.1 General requirements relating to the supply of ferro vanadium shall be as laid down in 1S : 1387-1967*.

5. CHEMICAL COMPOSITION

5.1 The chemical composition of the material shall be determined either by the method specified in IS : 1559-19617 or any other established instrumental/chemical method. In case of dispute the procedure specified in the latest edition of IS : 1559 shall be the referee method. For analysis of elements not covered in IS : 1559, the referee method shall be agreed to bewteen the puchaser and the supplier.

5.1.1 The percentage of residual elements for all the grades of ferro vanadium shall be as given below. If required by the purchaser, the manufacturer shall furnish an analysis for any of these elements on a cumulative basis over a period mutually agreed to between the purchaser and the manufacturer.

Element Percent, Max Element Percent, Max

Chromium 0.50 Tin 0.050 Copper 0.15 Zinc 0.020 Nickel 0.10 Molybdenum 0.75 Lead 0’020 Titanium .0’15

6. NOMINAL SIZE RANGES

6.1 Ferro vanadium is supplied in lumps or as crushed and screened particles. The particle size ranges and tolerances shall be in accordance with Table 2. The undersize values shall be valid at the point of delivery to the purchaser.

TABLE 2 PARTICLE SIZE

CLASS PARTICLE SIZE RANGE UNDERSIZE, MUX mm PERCENT BY MASS

NOTE - Maximum 10 percent by mass of over size is allowed in all the classes and no piece shall exceed 1’15 times the maximum limit of size range specified in two or three directions.

6.2 If the purchaser requires different size ranges and/or tolerances other than those given in Table 2, these shall be agreed between the supplier and the purchaser.

7. EXTRANEOUS CONTAMINATION

7.1 The material shall be reasonably free from extraneous contaminations like stage and non-metallic inclusions, etc.

8. SAMPLING

8.1 The material shall be sampled in accordance with IS : 1472-1977*.

9. PACKING

9.1 The material shall be supplied packed in suitable containers in quantities as mutually agreed to between the purchaser and the supplier.

10. MARKING

10.1 The material shall be marked with the following details:

a) Supplier’s name or trade-mark, and

b) Grade and subgrade.

*Method of sampling ferro-alloys for determination of chemical composition (first reuision ) .

10.1.1 The material may also be marked with the IS1 Certification Mark.

NOTE - The use of the IS1 Certification Mark is governed by the provisions of the Indian Standards Institution ( Certification Marks ) Act and the Rules and Regu- lations made thereunder. The IS1 Mark on products covered by an Indian Standard conveys the assurance that they have been produced to comply with the require- ments of that standard under a well-defined system of inspection, testing and quality control which is devised and supervised by IS1 and operated by the producer. IS1 marked products are also continuously checked by IS1 for conformity to that standard as a further safeguard. Details of conditions under which a licence for the use of the IS1 Certification Mark may be granted to manufacturers or processors, may be obtained from the Indian Standards Institution.
