Re: [MW:28633] ALLOY N08825 Welding and Testing requirements

Hi Greetings,

I had with ASTM B729 N08020 with ER 320 LR

Best practice for P45 materials is to use stringer beads as per QW-410 and SAES-W-016 para 6.8, DPT after root passes for both repairs and completion of root passes referring para 6.9.2 of SAES-W-016.

Again check for repairs and alert inspectors, as this is SA project and you have 100 % RT definetly look for cracks after root pass before DPT if found or after DPT.

100 % RT and 100 % DPT after each root pas completion.

More over please check with SABP, SAUDI ARAMCO BEST PRACTICES for P45 materials, i do not have the documents, but SABP has detailed practices.

Thanks.

Members,

Pl share any reference for ALLOY N08825 Welding and Testing requirements in detail, especially looking for ARAMCO requirements ( reference numbers atleast )

Thank you in advance


Thanks and Regards

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...
