The NORSOK M-650 certification was developed to ensure the highest standards of safety, quality, and reliability in materials used in the petroleum industry. Originally designed for harsh offshore environments like the North Sea, this standard applies to manufacturers of duplex and high-alloy austenitic stainless steel, as well as certain nickel-based alloys and titanium materials. It sets strict requirements to verify that manufacturers have the equipment, procedures, and expertise needed to produce materials that meet demanding operational needs.

A key aspect of NORSOK M-650 is its focus on the manufacturing process, from raw material selection to heat treatment and final testing. The certification process involves a detailed audit conducted by the purchasing company to verify compliance. Heat treatment procedures, such as furnace calibration, temperature uniformity, and quenching processes, are carefully monitored. Extensive testing, including both destructive and non-destructive methods, ensures that the materials produced meet the specified quality and performance criteria. These tests must be performed by accredited laboratories to maintain the integrity of the results.

For buyers, NORSOK M-650 certification provides confidence in the quality and reliability of the materials they procure, ensuring they are fit for critical applications. For manufacturers, achieving this certification demonstrates their ability to produce materials that meet stringent industry standards, enhancing their credibility and market competitiveness. The rigorous nature of NORSOK M-650 ensures that certified materials are consistent, reliable, and capable of withstanding even the most challenging operational conditions.
