BIS CERTIFICATION FOR NICKEL MARAGING STEEL BARS & RODS
IS 14652:1999

This standard covers the requirements for maraging steels containing 18 percent nickel in the form of bars and rods with nominal diameters less than 62.5 mm. The steel will be produced through vacuum induction melting, followed by consumable electrode vacuum arc remelting. The term "ingot" refers to a casting of consumable electrode vacuum arc remelted steel.

The supplier must conduct a chemical analysis on each vacuum or remelted ingot at a convenient stage of processing. The chemical composition thus determined must conform to the standard. All bars and rods must be free of visible cracks, seams, laps, shrinkages, and other serious discontinuities. Mechanical properties must conform to the requirements specified in the standard. To prevent rusting, each bar or rod must be coated with a protective coating.

TESTS

The following test shall be carried out in accordance with the standard.

• Tensile test
• Hardness test
• Chemical composition
• Elongation
• Non-destructive testing

Marking:

The bars/rods shall be identified with heat number, grade, and supply condition. 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). BIS grants a license based on a successful assessment of manufacturing infrastructure, quality control and testing capabilities, and production process during a visit to manufacturing premises.
