[MW:16389] Effect of a little amount of Excessive Sulfur in P355NL2(EN BS 10028-3-2003)

By Materials & Welding

Dear All

 

I test a specimen of P355NL2(EN BS 10028-3-2003).but there is a problem in chemical composition.

As per BS EN 10028-3(2003) max sulfur(S) limited to 0.01. we can ignore ± 0.003 as permissible deviation.

 

Below table is my material 's chemical analyze. As you can see sulfur is 0.014.

with consideration of ± 0.003 as permissible deviation , just it is 0.001 exceeded.

 

 

I need to know what is effect of this little deviation( in sulfur) in mechanical properties of this material???

Does it have a big effect ???

I want to use my material in LPG tank(operation temp. is -7c).is it important or I can ignore this 0.001 sulfur????

 

Best Regards,

M2M

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...
