Re: [MW:32323] PMI for ASTM A105 Flanges

Hi Babur,

https://www.intertek.com/non-destructive-testing/materials-testing/positive-material-identification-pmi/#:~:text=The%20device%20scans%20the%20metal,of%20pure%20carbon%20steel%20materials

Positive material identification is performed using either of the two techniques below:

X-ray Fluorescence (XRF) analyser: This is the most common method and the portability of the hand-held equipment allows Intertek to perform PMI on-site at our customers' premises. The device scans the metal material and identifies its key elements. However, it cannot detect carbon and some lighter elements and is not suitable for identification of pure carbon steel materials.
Optical Emission Spectroscopy (OES): This method can detect almost all types of elements including carbon and lighter elements and carbon steel. Although not as portable as XRF analysers, the equipment can be transported to sites and used at high elevations with proper lifting arrangements.

Dear Experts,
One of our contractor purposed PMI for ASTM A105 Flanges due to lake of inspection documents.
As my understanding PMI is suitable for HSLAS,
SS and DSS. For carbon Steel we can check if there is something happened im change of welding consumables for welding.
Please share your experience.

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change. Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...
