[MW:26826] Welding consumables requirement as per NACE MR0175 for carbon steels

By Materials & Welding
Dear All,

Welding consumables manufacturer [ER70S-2 & ER70S-6] has not stated in TC's that material complies to NACE MR0175  or not. As per my knowledge requirement as per NACE is

The welding consumable shall produce weld Zones meeting Hardness requirement of 250HV10. The Nickel in the welding consumable shall be less than 1%. Welding consumables and procedures that produce a deposit containing more than 1% nickel are acceptable after successful weld SSC qualification by testing in accordance with Annex B.


Also I would like to understand meaning of this line Welding consumables and procedures that produce a deposit containing more than 1% nickel are acceptable after successful weld SSC qualification by testing in accordance with Annex B.


Does that mean that if nickel is less than 1% [ 0.023% in my case] then I do not require any test as per Annex B of NACE and only carry out Hardness test and if its less than 250HV10 then its acceptable?


How can I satisfy my client that consumables available with me is NACE compliant

Regards,
Ankur

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...
