Re: [MW:31815] PWHT REQUIRED OR NOT?

Dear Sir,

If you say that stress receiving process required. My WPS also qualified with PWHT (SR) Process for SS 316 plate welding.

Pl. Suggest me.

When plate is bonded by explosion. The shape of the plate is disturbed, resulting in stresses and higher hardness. In order to straighten it up, it is always recommended to do a stress relieving heat treatment. It is nowhere specified, but to avoid issues during straightening and control hardness.

Mr.Patel, Doesn't require any PWHT after explosive cladding.  
if the customer wants you can, otherwise not.

Dear Expert,

I hope all are well.

My question is In after Tubesheet Bonding PWHT required or Not?

Base Material : SA 516 GR 70. (Thk : 45 mm )
Bonding Material : SA 240 GR 316. (Thk:5mm)

Tubesheet Dia : 3000 mm

( Note : Bonding plate SS 316 : 1 No joint on base material)

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

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...
