SS Cladding on High strength steel

SS Cladding on High strength steel

SS Cladding on High strength steel

Hi all,

Your advise is highly appreciated.

Is there any limitation to apply cladding of 304L or 316L on high strength steels like ASTM A516 grade 70? Or can you discuss if any practical difficulties are expected?



RE: SS Cladding on High strength steel

The limitations would be size of the sheets for cladding, geometry of the component, and no PWHT after cladding.

RE: SS Cladding on High strength steel

Firstly, can we get down to specifics: what means of cladding are you looking at, roll bonding, weld overlay, co-extrusion?

RE: SS Cladding on High strength steel

Some additional information which might be of interest to you.
-300 series cladding is used for corrosion resistance purpose only. From a sensible design perspective it's not advisable to include the clad thickness in nominal bvessel wall thickness calculation.
-Clad thickness generally specified are either 1/8" or 5/32" depending on the process media, corrosivity, design parameters,service life of the vessel... etc
-Thicker clad , more money.http://www.eng-tips.com/viewthread.cfm?qid=408590
-In a heat exchanger, tube sheets may be involve thicker cladding that specified above, subject to the parameters mentioned above
-Cladding on plates are done in the mill, mostly by roll cladding.Please seethe attachment for guidance.
-Many parts in a clad pressure vessel, e.g nozzles, fittings, Dished Heads and others as required , may involve clad deposition/restoration by welding. A barrier welding layer involving 309L(for 304L Clad) or 309LMo(for 316L Clad)needs to be deposited to take care of the dilution of weld metals. The final layer is always deposited by the electrodes/fillers matching the above specified chemistry.
-The typical limitations could be the shape ,size of the component.
-Performing PWHT after cladding.For C.S. vessels the nominal PWHT of CS base metal as per Sec-VIII, Div-1, is 1100Deg F, i.e. sensitization temperature for 300 series of austenitic steels.
-One may have to PWHT clad vessels at lower temperature(longer soak time) to avoid this scenario. UCL-66 provides guidelines to this.
-If PWHT is involved welding consumables & the clad base metals should involve IGC testing, ASTM-A-262, Practice-E(as minimum. These needs to be taken into consideration during the design stage.

RE: SS Cladding on High strength steel

Dear all,

Many thanks for your reply.

I would like to know what are the concerns during cladded to cladded pipe welding in this case. What re the probability of forming hard zones?

What are the different welding techniques that can be adopted?

What are the limitations that are expected when cladded fitting is selected? (Is there something special? I believe no)

@SJones, I am not considering WOL here. This is for heavy wall thickness piping.
@pradipgoswami , Thank you so much for the detailed explanation
@metengr, Thank you for the response.

White Paper - Design for Additive Manufacturing
With a growing number of parts manufactured directly by additive manufacturing techniques, it is important to lay down design principles suitable for such manufacturing processes and to ensure parts are designed for additive manufacturing. There are several factors that are to be considered at the design stage. Few such design issues in additive manufacturing are discussed in this paper. Download Now
