Re: [MW:26403] Re: Requirement of Solution Annealing for SS DIshed head after forming

check Table UHA-44.

Factors to consider are:
Alloy Grade
Design Temperature (lower and higher temperature range)
Strain after forming

The combination of the above factors is indicating if HT and at which temperature needs to be performed

Hi,

Please let me know What is the finishing forming temperature as per UHA-44.

Thanks,

Vipul

Dear All,
 
Greetings.
 
SS Vessel is being fabricated as per construction code - ASME SEC VIII DIV 1
 
SERVICE : SOUR Service
 
Material of Construction  for Dished Head - SA 240 316L, 20 mm Thickness.
 
I  believe stresses will be  induced in the material  during forming and as a result , Sulfide Stress Cracking (SSC) failure may occur during operation.
 
Whether Solution Annealing of SS Dished Head is required after forming?
 
Please give reference of any International Standard.
 
Thanks & Regards
 
Asad Azmi

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...

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

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...
