[MW:21671] Material test specimen

By Materials & Welding

Dear All,

 

What is the effect of the bellow paragraph (extracted from Saudi Aramco specification for Pressure vessels 32-SAMSS-004) on testing of material SA-516 Gr. 70:

My understanding:

  • For plate up to 20mm thickness, there is no effect as the material test specimen is required to full thickness as per paragraph 11.5.1 of SA-20, so it is not necessary to specify depth of 1/2T in the material ordering information and standard material testing is meeting the below paragraph. Please check and confirm
  • Also, for plate up to 100mm thickness, there is no effect if test specimen is full thickness as per paragraph 11.5.2 of SA-20, Please check and confirm
  • Only, for plate above 20mm thickness, in case specimen full thickness will not applied, as per paragraph 11.5.3 of SA-20, in this case the depth of 1/2T to be specified in the material ordering information, Please check and confirm

 

 

Please check and advice

 

Thank you in advance for your feedback

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...
