Drawability AISI 304 vs AISI 304L
Drawability AISI 304 vs AISI 304L
(OP)
Hi,
Type 304L is an extra low-carbon variation of Type 304 with a 0.03% maximum carbon content that eliminates carbide precipitation due to welding. As a result, this alloy can be used in the "as welded" condition, even in severe corrosive conditions. In many cases it eliminates the necessity of annealing weldments except for applications specifying stress relief. Type 304L has slightly lower mechanical properties than Type 304...
Regarding the last sentence... it could be said that AISI304 has better drawability vs AISI 304L due its slightly lower mechanical properties? I've heard (from comercial departmen of some stainless steel dealers) just the opposite. What do you think?
The consequences of such little differences on nominal mechanical properties (Yield strength, UTS, elongation) for each material, could be minimized in front others uncontrolled variables regarding the deep drawing processes... so, in my opinion is too hard to hold that AISI 304 drawability is better than AISI 304L drawability.
Any comments? Thanks in adance!

ERICHSEN TEST VALUES [mm]
Thickness 0,5 mm 1,0 mm 1,5 mm
AISI304 12 13 14
AISI304L 11,5 12 13
From where it can bee seen that for such nominal test the values are slightly higher for AISI 304 i.e. best (slighlty) drawability...
But the differences are very low so, as you say, more over chemistry, there are some other controlled and uncontrolled variables of the deep drawing processes that call in question that drawability (in a real deep drawing process) of one of them is better.
Thanks for your answer.

I can't see a basis for making a blanket statement either way.
