[MW:3842] RE: 3835] SA387 Gr.11 Cl.2 material welding.

By Materials & Welding

Dear all

With regard to Mr. P.Rao question :

1-      Use EB2 materials group.

2-      690 ±14 °C is better range for PWHT.

3-      Pay attention to 149 °C preheat and a suitable post heating.

4-      Check edges and bevels for hardness before welding.

5-      Check PWHT plus any intermediate treatment ( above 482°C) on LMP.

 

Best Regards

Subject: [MW:3835] SA387 Gr.11 Cl.2 material welding.

 


Dear all,

Can any body have experiance on welding of SA387 Gr.11 Cl.2 (1 1/4Cr-1/5 Mo)material with E8018-B3L, ER80S-B3L, EB3 type welding consumables(2 1/4 Cr-1Mo).

Higher composition consumables (B3L) are recommended?

Is there any change in PWHT is required as compared to standard PWHT cycle for SA387 Gr.11 Cl.2 material as per ASME Div.1.

Pl. share experiance on welding of subject material.

( Design Code : ASME div.1
MDMT : 0 Deg.C
Impact : 50/40)

regards

P.Rao

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...
