Re: [MW:22987] Normalized plate of A516 gr 70

By Materials & Welding
Dear Dani,
Write to mill and obtain letter of confirmation that heat treatment of plate done, also obtain authorization to stamp MT next Gr70 on plate, this may solve the purpose

Dear Expert,

 

Our vendor had purchased normalized plates from Sumitomo of steel making and Mill Cert clearly stated that the plates have been normalized but no sign or stamp "N" on plate. The problem is when the client reviewed and witnessed it, they don't believe that the plate has been normalized and the question is what test needs to be conducted to prove that the plate has been normalized?

 

For your info: what do you think if the client ask for the following test:

1.       Tensile test and the specimen needs to be normalized first prior to test, acceptance criteria as per mill cert.

2.       Scanning Electron Microscope (SEM), acceptance criteria: no residual stress in the plate.

 

Your quick response is highly appreciated.

 

Regards

Dani

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...
