[MW:611] Re: ELEMENT WHICH GIVE LOW TEMP TOUGHNESS TO SA333 Gr.6

Dear Owen,

 

Thanks for the reply. My doubt is if it is Mn which is responsible for impact toughness at low temperature then SA106 Gr.B also contains same Mn content as SA336 Gr. 6. In additon SA106 Gr. B contains traces of Ni whereas SA336Gr. 6 do not contain Ni. In that case why not SA106 Gr. B can be used as LTCS.

 

Awaiting your reply.

 

Regards,

There's an interesting discussion of this topic here: http://www.hghouston.com/dcforum/DCForumID1/251.html . I think it is taking far too simple a view to assume that one element controls impact toughness, which primarily depends on microstructure. Thus heat treatment, mechanical forming and all forms of hot and cold working are also very important.

DEAR MEMBERS,

 

CAN U PL. TELL ME WHICH ELEMENT IN SA333Gr.6 IS IMPARTING THE MATERIAL TO WITHSTAND IMPACT TOUGHNESS AT SUB ZERO TEMPERATURE.
