Anyone know how much less in tensile strength the A2 SS is as opposed to std bolts?

 

if its for chassis stuff you're asking the issue with SS is brittleness

 

It would be mainly on the bolts for gearbox to engine etc etc

 

A2 just means that it is normal Stainless steel. A4 is acid proof stainless steel.
They are generally available in strength ratings(property classes) of 70 and 80

A2(A4) - 70, tensile strength = 700N/mm2
A2(A4) - 80, tensile strength = 800N/mm2

8.8, tensile strength = 800N/mm2
10.9, tensile strength = 1000N/mm2
12.9, tensile strength = 1200N/mm2

But there are more factors to take into consideration before using stainless bolts.

 

I would just use stainless to replace non load bearing OE bolts (pulley covers, brackets etc)

 

i fucking hate stainless LOL

 

not a big fan myself Gareth but cant think of what else to use..
