Kathasaritsagara malayalam pdf Vararuci also transliterated as Vararuchi Devanagari: is a name associated with several literary and scientific texts in Sanskrit and also with various legends in several parts of India. This Vararuci is often identified with Ktyyana. Community Texts. Uploaded by kathasaritsagara malayalam pdf Kathasaritsagara Ocean of rivers of stories is a famous 11thcentury collection of Indian legends, fairy tales and folk tales as retold by a Saivite Brahmin named Somadeva. Nothing is known about the author other than that his fathers name was Ramadevabatta. A 16th century folio from an Indian retelling of the Kathasaritsagara.

A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the Central Secretariat has the same status as the official versions. Melting process.

Manufacture of the product. Heat treatment condition and surface finish at the time of delivery. Cast separation. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, and conflicting national standards withdrawn, by July at the latest. The United Kingdom will issue a non-conflicting national addition which describes a steel used in the United Kingdom but is not included in this European Standard.

Page 3 EN Page 5 EN Steel grades and chemical composition cast analysis 1 2 3 4 Elements not quoted in this table shall not be intentionally added to the steel without the agreement of the downloadr, other than for the purpose of finishing the heat. All reasonable precautions should be taken to prevent the addition from scrap or other material used in manufacture, of such elements which affect the hardenability, mechanical properties and applicability.

Boron in this case is not added to increase hardenability but to improve the toughness of the case-hardened zone. The United Kingdom will issue a non-conflicting national addition which describes a steel used in the United Kingdom but is not included in this European Standard.

Time for austenitizing as a guide: 0,5 h minimum. The carburizing temperature will depend on the chemical composition of the steel, the mass of the product, and the carburizing medium. Steel and iron. Metallic products. All other steels covered by this European Standard are alloy special steels. T ISO Test method scales A.

Table 5 and Table 6 are allocated in accordance with EN If the downloadr does not indicate his wish to implement one of these options.

See also Table 3. If agreed at the time of enquiry and order alloy steels with restricted hardenability scatter bands given in Table 6 shall be supplied. Where improved machinability is required.

The method and permissible depth of defect removal. The type of document shall be agreed upon at the time of enquiry and order. NOTE It is more difficult to detect and eliminate surface discontinuities from coiled products than from cut lengths. If the order does not contain any specification of this type. EN specifies requirements of ultrasonic testing of flat products of thickness equal to or greater than 6 mm and EN specifies requirements of ultrasonic testing of steel bars see A.

This should be taken into account when agreements on surface quality are made. The calculation method is left to the discretion of the manufacturer. The temperature for quenching shall comply with Table 8 of this document. In addition. Visual and dimensional inspection w 8. If agreed at the time of enquiry and order the manufacturer shall give sufficient information about the calculation for the customer to confirm the result. Remarks 10 Non alloy steel grades 1.

Where requirements are made on hardenability see Table 5 and Table 6. In the first case the upper limit for the manganese content may be increased by 0.

All reasonable precautions shall be taken to prevent the addition of such elements from scrap or other material used in manufacture which affect the hardenability. Boron is in this case added not for increase of hardenability but to improve the toughness of the case hardened zone.

Steels with improved machinability as a result of the addition of higher sulphur contents up to around 0. Ca-treatment modern method or lead may be supplied on request. For steels with a specified sulphur range 0. Hardness HRC at a distance from quenched end of test piece in millimetres of 1.

For special procedures. The carburizing temperature will depend on the chemical composition of the steel. The kind of quenching agent depends on. Time for austenitizing as a guide: The lower hardening temperatures are in each case to be preferred. Time for tempering as a guide: If the steels are direct hardened.

In cases of dispute. The test shall be performed near the surface The tests shall be carried out separately for each cast as indicated by "C". Products with different thickness may be grouped if the differences in thickness do not affect the properties.

In all other cases. If the product dimensions do not permit samples to be taken for the end quench hardenability test. The quenching temperature shall be as specified in Table 8. For sample preparation.

C hardness in the end quench hardenability test continued 22 w w w. C hardness in the end quench hardenability test continued w w. C hardness in the end quench hardenability test continued 24 w w w. C hardness in the end quench hardenability test continued 26 w w w.

C hardness in the end quench hardenability test continued 28 w w w. C hardness in the end quench hardenability test continued 30 w w w. Otherwise one test piece per cast shall be inspected for the determination of the austenitic grain size. In cases of dispute about the analytical method. Other products shall be non-destructively tested in accordance with a method to be agreed at the time of enquiry and order and to acceptance criteria also to be agreed at the time of enquiry and order. If specific testing is ordered.

In such a case the micrographic investigation is not necessary. The aluminium content shall be given in the inspection document. NOTE The requirements for non metallic inclusions content apply in every case.

The details of these requirements may be agreed upon between the manufacturer and the downloadr at the time of enquiry and order if necessary. The fine grain structure is normally achieved. In most cases. After carburising.

If verification is agreed then the method and acceptance limits shall be agreed at the time of enquiry and order. Unless otherwise agreed at the time of enquiry and order. In this case a minimum reduction ratio or a minimum thickness deformation ratio of e.
