Re: [MW:5757] Welding of SA 240 TP 410S material.

By Materials & Welding
Rao,
 
410 material is martensitic stainless steel and 410S material is Ferritic stainless steel. These are basically 13CR stinless steel selected for certain service requirement. The P.No of 410S is P.No.7.
 
The preheat recommended for 410S is 10degC and the Interpass temperature is 260degC. It can be welded using E309L/Ni based electerode / 410 electrode. Normally PWHT can be waived if E309L electrode is used.
 
If you prefer to use 410 electrode, then a preheat of 150degC is recommended and the interpass temperatuure shall be 100 degC higher than the preheat.

Dear all,

Can any body share the experience in welding of SA240 TP410 Material.

I have a Vessel consists SA387 Gr.11 Cl.2 material cladded with SS410S.

Internal Piping material : SS410S thickness 10-15mm.

Construction Code : ASME SEC VIII Div.1.

Welds in SS410S will under PWHT of low Low alloy steel.

Need guidance in Preheat & interpass temperature of SS410 material welding (Consumable selected for welding of SS410S is 309L type).

regards

P.Rao

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...
