RE: [MW:22698] Hardness Value of Inconel 625

By Materials & Welding
Hi,
 
Pls find the attached hardness conversion table.
 
as per this 35 HRC = 345 HV.
 
For vickers hardness tesing the surface finsih is more important. pls refer std ASTM E92 for specimen prep. and surface finish of the specimen. Even slight variation in surface prep. may lead to wrong measurement.

Dear All,

Thank you for your valuable comments. I am getting an average value of 376 HV10 on HAZ & parent metal side of my PQR test coupon(ASME SEC IX). Should I reject the test coupon...?

hi,
 
as per NACE MR0103-2005, it is 35HRC.
 
I have attached snapshot of the standard. Pls refer the attachment and correct me if i am wrong.

Hi,

It is not specified in code, if you refer to shell MESC, it is 32 HRC.

Dear Experts,

What is the hardness value of Inconel-625 (ASTM B444 UNS N06625)?

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...

The Schaeffler and Delong diagrams for predicting ferrite levels in austenitic stainless steel welds

By Materials & Welding
Introduction Ferrite is important in avoiding hot cracking in during cooling from welding of austenitic stainless steels. 'Constitution diagrams' are used to predict ferrite levels from the composition by comparing the effects of austenite and ferrite stabilising elements. The Schaeffler and Delong diagrams are the original methods of predicting the phase balances in austenitic stainless steel welds. Nickel and chromium equivalents A 'nickel equivalent' is calculated for the austenite stabilising elements and a 'chromium equivalent' ferrite stabilising elements. These are used as the axes for the diagrams, which show the compositional equivalent areas where the phases austenite, ferrite, martensite (and mixtures of these) should be present. Although intended to show the phase balance of weld fillers, these diagrams can also be used to illustrate the phase balance of the 'parent' material. There are different diagrams for dif...
