[MW:6124] Re: Welding of ASTM A 335Gr.P11

By Materials & Welding
COMMENT BY C C GIROTRA (Weldwell Speciality Pvt Ltd,Mumbai)

The low carbon type wire and electrodes in P11 and P22 are used where
PWHT is not feasible due some problems or if the thickness of the
plate/pipe to be welded is 12mm max. Such low carbon consumables yield
lower residual strees hence if PWHT is not carried out there are no
problems in operations,Foe example for steam turbine casing in a
running power plant PWHT is not possible.So E8018B3L electrode and
Filler wire ER90SB3L wire is used.

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...
