Re: [MW:34391] 316Ti material - GTAW rod selection

By Materials & Welding
Titanium and Niobium provide the same effect But Titanium forms carbide at high temperatures and sometimes it may not form carbide also Titanium containing SS GTAW Filler rod can be used with an inert shielding gas but due to the above problem, it is always preferable to use Niobium containing SS Filler rod.

Thanks & Regards

SS316Ti  contains Titanium which forms Titanium carbide and thus prevents Intergranular cracking in SS, the composition of ER318 is similar to SS 316 except with the addition of Niobium (columbium) which forms Niobium carbide and provides the stabilization effect and prevents Intergranular cracking.

Thanks & Regards

Good morning Sirs,

Thank you for your reply for my query.

Could you please explain,  why this class ER318 is suitable to weld 316Ti. 

Please provide any link for my knowledge. 

Regards,

Dear Sirs,

Please guide for the selection of GTAW welding rod to weld SS 316Ti pipe shell.

Can we use ER318, as I searched in Google?

Please  confirm and also advise for any special wedding parameters,  shield and purge gas requirements for this welding. 

Regards, 
Saravanan Sornam,

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...
