Talking to an expert in the stainless steel industry, he pointed out that China has been very competitive on price, but very unreliable on quality. There are many types of stainless, and design and production engineers need to know that any batch conforms exactly to specs for the type. It is on this info that they base their calculations for load-bearing, ductability, fireproofness etc etc, some of which are critical.

I'm sure that China will get the concept of quality control right in the future - but for now?
