IS 5517:1993

In this competitive scenario, it isn't easy to survive in the market without a standard quality and certified product. BIS license may also be required to sell products in the Indian market.

To get BIS certification and produce a standard quality product, the manufacturer must ensure that their product must follow the specified Indian standard.

Let's take a closer look at IS 5517:1993 for steels for hardening and tempering.

This standard specifies the technical and delivery requirements for wrought alloyed and unalloyed steels in the form of bars, rods, flats, plates, forgings, etc to be used in hardened and tempered conditions. This standard's steel is generally intended for forging and machining of parts for engineering or automobile purposes.

IS 8910:1978 specifies the general requirements for material supply. Steels covered by this standard must be ordered and delivered on any of the basis specified in table 1 of the standard.

Unless otherwise agreed to in the order, the processes used in the manufacture of the steel and the product shall be left to the manufacturer's discretion, but the steel shall be fully killed. As determined by macroetching and ultrasonic testing, sufficient reduction and discard must be made to ensure freedom from piping, harmful segregation, and so on. The material must be free of surface and material defects that could impair its end-use.


Tests shall be done in accordance with the methods specified.

  • Chemical analysis
  • Hardness
  • Mechanical properties
  • Grain size
  • Hardenability
  • Dimensional & tolerances
  • Additional tests


All bars of 50 mm Dia or equivalent section and above must be stamped or suitably marked at the end with the heat number and the manufacturer's name or trade mark. Bars in smaller sections will be tied to appropriate bundles with metal tags containing the information. The Standard Mark (ISI Mark) may also be applied to the material.

Manufacturers must obtain a BIS license from the Bureau of Indian Standards to use a standard mark (ISI Mark). The Bureau grants a license based on a successful assessment of manufacturing infrastructure, production process, and quality control and testing capabilities during a visit to its manufacturing premises.
