Re: [MW:22980] Normalized plate of A516 gr 70

By Materials & Welding
Addition to my previous reply on the below query:
As per 13.1.2 of ASTM A20 (Plates for Pressure Vessels)
"Plates that are required to be heat treated, and have been so heat treated, shall be marked by the party that performed the heat treatment, with the letters "MT" (denoting material treated) following the required ASTM designation mark"

#yiv9294488321 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.  RegardsDani

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...
