[MW:30055] Re: Requirement of double Normalizing of SA-516 Gr.70

By Materials & Welding
this is all because of asme sec 8 div1 ucs 85 , ug 85
1.if you didint purchase  2 normalise plate + pwht than when you doing simulation test its get chances of fail so its  for safe side purchase plate from mill  already fulfill this condition its give confidence for simulation .if you have same kind of palte at your fabrication workshop try this with non 2 normalised + non pwht plate you will get result alter to your requirements

same concern for wps  .

In our recent project i encounter one problem.

Material Grade : SA-516 Gr.70 Supply condition : Normalized
Dished end : Ellipsodial
Thickness : 45 mm
Forming process : Cold forming
Dished end have one cordal seam
Impact required at : -46 deg. C
so during cold forming vendor need one intermediate normalizing. and as per client requirement one more normalizing performed after complete dished end forming. So, total 2 time normalizing have to perform.

So, my question is ; 
(1) During plate order i have to take 2 normalizing cycle simulation ? Yes Or No? With Reason
(2) May I take benefit of Clause UCS-85 (i) of ASME sec-8 Div.1?
(3) Is same clause applicable for welding?
(4) And If i will perform double normalizing then I have to simply double the normalizing time or 2 separate normalizing i have to perform?
(5) What will be effect on weld and base material after 2 time Normalizing?
(6) if any one encountered such issues . please help to solve

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...
