INTRODUCTION

Steel for volute and helical springs is a type of steel specially made for crafting coiled or spiral-shaped springs. These springs are used in things like car suspensions, big machines, and other mechanical stuff. This steel is strong and flexible, perfect for making these springs.

To ensure the product quality of steel for volute & helical springs, the Bureau of Indian Standards (BIS) has made it mandatory for manufacturers to undergo BIS registration and obtain the BIS ISI mark before selling it in the market. Manufacturers can use the ISI Mark on their products only after obtaining a license from BIS that is granted after BIS registration. The presence of the ISI mark on a product indicates that it complies with BIS's stringent quality standards.

IS 3195: 1992 covers steel for volute & helical springs. This standard specifies the requirements for flats and rounds of steel intended for use in the manufacture of the volute and helical springs for railway rolling stock. Steel ingots and billets that meet IS 8052:1976 can be used to make flats and rounds that meet this standard.

REQUIREMENTS FOR IS 3195:1992

1.     The steel shall be of the eight grades as specified in the standard.

2.     Steel may be produced using any method of steel making other than the Bessemer process.

3.     It must be followed by secondary refining or vacuum melting.

4.     For any given size of finished steel product, the size of ingots, billets, or continuous cast billets shall be such that a minimum reduction ratio of 16:1 from the product's minimum cross-sectional area is ensured.

5.     Marking shall be done as per IS 3195:1992.

6.     Each bar shall be marked with the manufacturer's name or trade-mark, grade, and the cast number or identification mark by which steel can be traced back to the cast from which it was made. Standard Mark (ISI Mark) may also be applied to the material.

7.     Manufacturers must obtain a BIS license from the Bureau of Indian Standards to use a standard mark (ISI Mark).
