Hi All,
Form tolerances does not require Datum refrences. but i have a doubt in this as follows.
When we measure the Form tolerance (either Flatness, Straightness etc.) obviously some part feature must be in contact with the Surface table or plate. In this case if the mating part feature with...
Hi All,
I understand the GD & T rule 1 & it says
Perfect form at MMC, if it is so
then Why not perfect form at LMC also
for ex. for the shaft dia. of 20 +/- 0.1, the LMC is 19.9 mm
If all the element are at LMC of 19.9 mm, then it is also a perfect form ? Is it not ?
Please any one clarify...
My understanding about Duplex S.S is mostly used in pressure vessels. Ferrite content testing is important quality test for its welding because mostly it has to perform in corrosive environment with high thermal stresses.
But,we are using Duplex SS (EN std. 1.4462)in rolling stock underframe...
