BIS CERTIFICATION FOR COLD-ROLLED MEDIUM, HIGH CARBON AND LOW ALLOY STEEL STRIP
IS 7226:1974

This standard specifies the requirements for cold-rolled medium, high carbon, and low alloy steel strips with a thickness of up to 3 mm and a width of up to 330 mm intended for general engineering applications.

IS 1387:1967 specifies the general requirements for the supply of cold-rolled medium, high carbon, and low alloy steel strip. Cold-rolled steel strips must be supplied annealed or annealed and re-rolled. Cold-rolled steel strip must be delivered in coils.

Strips must be made from steel produced using an open hearth, electric furnace, basic oxygen, or duplex process, or a combination of these processes. If any other process is used in the manufacturing, the purchaser must be consulted first. If the basic oxygen process is used to manufacture steel, the nitrogen content must not exceed 0.007 percent.

The surface of the cold-rolled steel strip must be free of harmful surface defects such as scales, rust, blisters, laminations, pitting, cracked edges, and so on. Cold-rolled steel strips must have a bright finish.

TESTS

The following tests shall be carried out in accordance with method specified.

• Chemical composition
• Hardness test
• Edge condition
• Rolling tolerance
• Surface finish

Packing and Marking:

Cold-rolled steel strip must be properly packed to prevent rusting and damage during transit. Every coil of strip shall be legibly marked with the manufacturer's name or trademark, grade, size, and cast number, or any other identification mark that allows the coil to be traced back to the cast from which it was made. The ISI Certification Mark may also be applied to the material. The Manufacturer 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.
