[MW:35725] Dismillar material Welding

Dear experts, 

In my Hydro Electric Project  materials using A517Gr.F and A537CL-II. 

For A517Gr.F using E 11018M and A537CL-II using E 9018M.

Only one joint have a A517Gr.F with A537CL-II. 

Which Electrode is better for PQT. 

Your valuable guidance is highly appreciated.

Thanks with regards, 

S.Maharajan.

Re: [MW:35727] Dismillar material Welding

We require an electrode that is compatible with the higher strength and toughness of A517 Grade F, and 

It should also maintain a good weldability with A537 Class 2. 

E11018 is preferable for welding A517 Gr F, A537 Cl II, or dissimilar joints, as it matches the strength 

and toughness requirements of both materials and is designed for high-strength, low-alloy steels.  

E9018M is suitable for A537 Cl 2, and provides good toughness but may not meet the impact requirements 

for A517 Gr F at low temperatures.   

Use an appropriate preheat (150°C–200°C) as per welding codes to avoid hydrogen-induced cracking 

and interpass temperature (200°C) to control overheating.

C Sridhar.

Re: [MW:35729] Testing of heat resistant steel tubes PQR-ASME IX

If your client is referencing QW-466.19 in ASME Section IX for a bend test, it's likely a misunderstanding or 

misreference, as this clause does not appear in the 2017, 2021, or 2023 editions, nor in earlier editions.

Inform your client that QW-466.19 doesn't exist in recent ASME Section IX editions on the intended clause or test 

requirements. We can proceed with standard bend test requirements under QW-466.1 (general bend test figures) 

and QW-163 (acceptance criteria).

Re: [MW:35731] Testing of heat resistant steel tubes PQR-ASME IX

 ASME uses and approves materials from ASTM and other sources for use in pressure-related applications, 

assigning them a special ASME designation (typically starting with "SA-"). These are called ASME-listed 

materials, but not "ASME grades".

In this sense, ASME does not invent material grades. but approves and lists them for use for the code applications.   

for example,

ASTM A516 → ASME SA-516

ASTM A240 → ASME SA-240.

Hope it is clear.

Re: [MW:35733] Testing of heat resistant steel tubes PQR-ASME IX

ASTM A297 Grade HP (Cr 24-28% & Ni 33-37%) is a heat-resistant stainless steel casting alloy commonly used in high-temperature 

applications. ASTM A297 Grade HP (ASME sec II Part A and its UNS number is N08705) does not have a direct, one-to-one equivalent 

in ASME standards and modified slightly for specific applications (example: pressure vessels, piping).

For practical purposes, in ASME codes, Grade HP would be referenced under SA-297 Grade HP for applications like furnace parts, heat 

treatment equipment, or other high-temperature cast components. For a specific purpose like piping, it is referred to as ASME B16.5 -for 

flanges.
