Re: [MW:26396] Re: Welding of ASTM A 335Gr.P11

By Materials & Welding
There will be depletion of C and Hardness also will increase if u use ER90S-B9 and E9018-B9 and soaking time of P11 will not reduce much of Hardness of B9 weld metal

Dear sir,

  Thanks for your valuable  reply, i also suggested the ER-80SB2 & E-8018B2 for welding of P11, but the chinese has saying that,they will use ER-90SB3 & E-9018B3 instead of ER-80SB2 & E-8018B2 . Till now QPS & PQR also not prepared.for that reason only i asked here. i have to approve the proposed WPS. please let me know the soaking temperature have to given when ER-90SB3 & E-9018B3 used for P11.Is there any effect on the hardness values when we will give soaking temperature of P11.

Thanks & Regrds

Dear Friend,

For  welding of SA335-P11 pipe you can use ER-80S-B2 & E8018-B2 for welding, no need to use 
ER-90SB3 & E-9018B3. 
For PWHT you can use 650-660 Deg C with soaking time respect to thickness of job or refer ASME secVIII div 1 standard.
Hope that i have clarified.

Dear sir,

  i'm having one doubt that, can i use ER-90SB3 & E-9018B3 for welding of SA335-P11. if suppose will use then what is temperature should have to follow for the PWHT. if we follow the soaking temperature of P11, then is ther any chance to affect on the hardness properties.

Thanks & regards

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...
