[MW:0] RE: Cr. % Changing in heat Treatment

By Materials & Welding

What is the %Cr you are getting? Normally this various is possible even if you take at different locations, and not because of HT . +/-10% variation over the specification requirement can be accepted in PMI. If you want precise readings try other methods.

Subject: Cr. % Changing in heat Treatment

 

Dear Sir,

 

I am Israr Ahmed working as a surveyor in one of the co. in mumbai,

Recently I witnessed a PMI test on Raw Material EN10083-34CrMoNi6.I was getting the result as per the requirements.

Now after machining and Heat Treatment of the same material I witnessed the PMI. The cr. percentage is getting down by 0.1percentage.

Both Time PMI done by a same Lab.

 

Could you pls guide me what may be the reason.

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

By Materials & Welding
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...
