BIS CERTIFICATION FOR COLD ROLLED CARBON STEEL STRIPS IS 4397:1999

INTRODUCTION

Cold rolled carbon steel strips are flat metal pieces made smooth by rolling them through machines at normal room temperature. These strips are used to make cages/retainers for ball and roller bearings, following specific rules to ensure they are of the right quality and fit.

IS 4397:1999 sets forth the requirements for cold-rolled carbon steel strips specifically intended for the production of ball and roller bearing cages/retainers. These strips, classified into grades such as DD (Deep Drawing Quality) and EDD (Extra Deep Drawing Quality), must adhere to the specified standards for use in creating cages/retainers for ball and roller bearings. The strip shall be supplied exclusively in the skin-rolled temper, ensuring a non-scalloping surface, and suitability for processes like blanking, deep drawing, and piercing.

To assure the quality and compliance of these cold-rolled carbon steel strips, manufacturers have the option to pursue ISI Registration for cold rolled carbon steel strips. This involves obtaining ISI Certification for cold rolled carbon steel strips, ultimately resulting in the issuance of the ISI Certificate. This certification serves as a mark of adherence to standards, affirming that the cold-rolled carbon steel strips meet the specified requirements for their designated application in bearing cages/retainers.
