RE: [MW:31184] Re: Annealing and Normalizing temperature for F316 & SS410

By Materials & Welding

SURESH,

 

Yes, SS410 steel can be purchased, in annealed condition, or in a tempering condition with prior normalization, as stated in ASTM A479, point 4.4.1. But the question is what are you going to do with the steel, are you going to weld it, machine it, or use it directly in its state of supply (annealed)?

If you are going to use it in a welding condition, since the annealing structure is lost, instead hard hardening structures such as martensite are formed. Then a tempering must be done to preserve the best hardness and toughness properties and that the piece does not suffer from hydrogen-induced cold cracking.

Thanks Mr.Ramon Briceno

 

But my client is suggesting to do annealing for ASTM A473 Typ410 at the temperature of 950 C (Customer mentioned TDC). Is there any adverse effect on the change of hardness?

Suresh Kumar

Dear Experts

Kindly let us know the Annealing and Normalizing temperature for below material grade

 

1.ASTM A473 Typ410- Annealing and Normalizing temperature

 

2.ASTM A182 F316- Solution Annealing and Normalizing temperature

 

 

Kindly let us know this temperature is anywhere mentioned in the standard

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...
