What is the difference between bolts A320 L7 and A320 B8? Can it be understood that L7 refers to carbon steel bolts while B8 refers to stainless steel bolts? In terms of appearance, is it correct to say that L7 bolts are black and B8 bolts are white?

Bolt A320 L7 is a bolt used for low-temperature carbon steels such as LCB; its matching nut is A194 4. Meanwhile, A193 B8 is a stainless steel bolt, with A194 8 as its matching nut, and it is used for stainless steel CF8 valve bodies. If sulfur resistance is required, then A193 B8M /A194 8M is needed.

Come in and learn*. The choice of what to use is generally determined by the design, right?
