In rolled steel the grain orientation are parallel to the rolling direction and this help for improved mechanical properties in the rolling direction in contrast to the transverse to rolling direction. A specimen orientation perpendicular to the rolling direction will ensure that material is able to offer the minimum specified properties in the worst scenario. This clause doesn't apply to the casting or forging material.

Considering the XYZ axis of plate where X is the rolling direction or length, Y is the plate width and Z is the thickness. The mechanical properties are degraded in decrements order of X-Y-Z where Z will have the lowest values.

Thanks & regards

I did it from Google also but I didn't understand?
I opened ASME sec 2 part A and sa370 I observed orientation of specimen for testing.i got we have to select orientation of specimen as per code but my question y mostly spec says long axis of specimen should be perpendicular to direction of rolling if we take parrel than what will be effect?

Re: [MW:34105] SA266 GR4N 4 Cycle SPWHT

By Materials & Welding
Hi,  You are correct, Minimum refers to the one cycle for which this part will expose until final work shop PWHT. hence mill test certificate shall include this.  Max. SPWHT, refers to additional cycles of heat treatment that are reserved for future repairs during equipment lifetime.  Again, these simulated no. Of cycles shall be specified in MTC.  The idea is we need to make sure that steel mechanical properties are not compromised upon exposure to multiple repairs (i e 4 cycles in your case).  One could say, if steel is subjected to 4 cycles and is ok, then it should by defacto be good for one cycle, yet, this is wrong assumption cause mechanical problems and microstructure of materials varies accordingly based on no. Of cycles for which material will expose. This is apparent in alloy steel and especially for impact test values as an example.  In your case, this forged CS with properties before PWHT can be understood to be " as forged" condition (i.e. Wit...

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...
