Re: [MW:31568] Welding of 410 Stainless Steel

By Materials & Welding
Dear Vikas ji 
 tempering temp of 610°C ( 20°C below tempering temperature of the material).  

This PWHT temp is too low for softening martensite.
,make it at 720-730 Deg C for @2 hrs 

Regards

Hi

I am looking to weld 410 wrought stainless steel, there is a requirement to build up parent material because of incorrect machining.

AWS A 5.9 ER410 is the filler wire.

Considering the carbon and Chromium content, looking for a preheat of 200°C with maximum interpass as 315°C.

I take it ,No interruption during welding will be good for joint. Material will be constantly maintained at the minimum preheat temperature during welding.

 

For post weld heat treatment , I am thinking of bringing the material to 100°C (This is to ensure that there is complete transformation of the weld and HAZ to martensite ) and then follow this with PWHT for 4 hours.

 

I am thinking of tempering temp of 610°C ( 20°C below tempering temperature of the material).

 

Any recommendation in this regard will be greatly appreciated.


Thanks & best regards


Vikas

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...
