[MW:16582] RES: 16574] ASTM A516 Gr.70 normalizing

By Materials & Welding

M. Farhang;

 

The plates can be supplied “normalized” or “as rolled”; it depends how it was ordered:

 

 

In my point of view, for data book issues and assured properties , you should have the original material certificates that guarantee the treatment imposed to the material’s specific  lot. Metallographic tests  can guarantee only the conditions for the specific plates inspected.

 

 

Special attention to the AWS D1.1 regarding precaution when using ASTM A 500 class where toughness properties are required.

 

 

Gest regards

Dear All

 

I need to know how can understand that ASTM A516 Gr.70 is normalized or not?

 

Somebody told me:

 “according to clause 5.3 of ASTM A516 standard (attached), when we apply charpy impact test on a material and it pass the impact test successfully, we can say the material is surly normalized but if the material can’t pass the impact test, we shall apply metallographic test to understanding if the material is normalized.

 

And somebody said me:

“we have just 1 way to know that is the material normalized or not. And its metallographic test.”

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...
