[MW:35876] 40mm thick SA515 with 3mm Inconel 600 Clad Reactor

By Materials & Welding
Dear Experts,

We seek your valuable insights regarding the welding, shell rolling, and dish forming processes for a clad steel reactor comprising 40mm thick SA515 Gr.60 base material with 3mm Inconel 600 cladding ( Produced by Explosion Bonding Method).

Preliminary references suggest that pre-heating may be necessary during rolling, forming, and welding operations due to the dissimilar material combination. Additionally, maintaining inter-pass temperatures between 100°C and 250°C is advised to prevent clad layer disintegration.

ENiCrFe-3 has been recommended as a suitable filler metal for both cladding and transition layer welds.

As we are  new to this material combination, we would greatly appreciate expert opinions on critical considerations, best practices, and potential challenges associated with these fabrication steps.

Looking forward to your guidance.

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...
