BIS CERTIFICATION FOR CASE HARDENING STEELS IS 4432:1988

INTRODUCTION

Case Hardening Steels are a type of steel used for specific purposes where the surface of a component needs to be hard and resistant to wear, while the core remains tough.

ISI 4432:1988 covers Case Hardening Steels. This standard specifies the technical delivery requirements for case-hardening wrought low-carbon unalloyed and alloyed steel bars, billets, rods, and finished forgings. In general, the steels are intended for forgings and the fabrication of case-hardened machines or automobile parts.

Case hardening of parts refers to parts that have been carburized or carbonitrided on their surface and then hardened to produce a high degree of hardness in the surface zone while the core material is relatively tough. The general requirements for material supply shall conform to IS 1387:1967.

To ensure the quality and conformity of Case Hardening Steels, manufacturers must undergo ISI Registration for case hardening steels, obtain ISI Certification for case hardening steels, and display the ISI Certificate for case hardening steels.
