Introduction

An eminent aerospace manufacturer in India went through a situation where their 18% Nickel Maraging Steel Bars and Rods were rejected several times, even though the steel was of standard quality. The issue was that the steel did not have a BIS certificate under IS 14652:1999, which is a must for defence and aerospace projects. In the absence of such a certificate, even a top-quality steel can be turned down in important contracts. BIS certification is a means to an end to ensure that the product is in accordance with Indian standards, thus gaining the trust of the client and increasing market credibility.

What is IS 14652:1999?
IS 14652:1999 is a standard issued by India defining the necessary features for 18% Nickel maraging steel bars and rods. The standard essentially determines that the metal should have the correct chemical composition, strength, and be of the required level of reliability for use in aerospace, defence, and precision tooling industries.
Key points:

- Specifies chemical composition limits, including nickel, cobalt, molybdenum, titanium, and aluminium.
- Covers requirements for 18% Nickel maraging steel bars and rods.
- The standard also specifies the tests to be performed like ultrasonic testing, hardness tests, and microscopic structure inspection.
- Ensures uniform quality and performance for critical applications. ISI MARK
- Mandatory for BIS certification of 18% Nickel Maraging Steel Bars and Rods.
Why is BIS Certification Mandatory
BIS certification is a must for 18% Nickel Maraging Steel Bars and Rods that is done to ensure that the products conform to the Indian standards of quality, safety, and performance. In the case of sectors such as aerospace, defence, and precision tooling, even slight changes in the chemical composition or mechanical properties may result in the failure of the instrument in the most critical applications.
Key reasons for mandatory certification:
- It confirms that the product complies with IS 14652:1999 standards.
- It is a source of material quality and mechanical strength.
- It increases the trust of the client and the credibility of industrial and government projects.
- It avoids the rejection of products participating in tenders and high-value contracts.
- It helps in lessening the chances of legal issues, recalls, or operational failures.
