Hi Imitiyaz
The weldability of stainless steel depends on which SS material you are dealing with. The carbon and alloy content has an influence on weldability. Typically your "L" grade austenitic stainless steels, such as Type 316L SS will have improved weldability compared to just...
Hello
can anyone assist with suitable materials (cost effective) for stacks and ducting susceptible to acid dew point corrosion. The flue gases contain substantial amounts of SO2/SO3. Operating temperatures range from 80 degrees celcius to about 300 deg celcius depending on equipment.
Thanx

Sigma phase can sometimes be found in austenitic stainless steel weld metal. It is most commonly encountered after long exposure times at temperatures of 600 to 870 degrees celcius. Sigma phase is associated with ferrite (contained in duplex stainless steels) and thus...
Hi Bassam<br>Type 316 is a molybdenum containing stainless steel and often finds use in sea water applications. Sea water is deleterious to SS in that it contains high levels of chlorides which can cause pitting corrosion or worse stress corrosion cracking (SCC). Generally...
Hi<br>What materials do you want you join? Stainless steels? I find that TWI-"Job knowlege for welders" (<A HREF="http://www.twi.co.uk" TARGET="_new">www.twi.co.uk</A>)is very useful and a lot of info on welding processes for different materials can be gotten from their...
An outer clutch ring of a winder, fabricated from BS 3100 Grade A2 cast steel, has developed a through crack extending from a hand-hole. Possible repair options include welding (full penetration weld possible) or alternatively cold repair using metalock techniques. I am...
