I find this 1935 comment by Dr. Horace W. Gillett insightful and  incredibly current:

We start out with some innocent thing like 18:8 (UNS S30400), apparently simplicity in itself because it is austenitic, and so can’t be heat-treated in the usual way, and apparently resistant to corrosion of many types. As we go along, we bump into carbide separation, embrittlement corrosion by pitting where it was not expected, and what not, and we have to go into the situation with a fine-tooth comb to eradicate the bugs. Many man-years have to be spent before the possibilities and limitations are fully explored. A mass of specialized literature and a lot of practical experience in the minds and hands of skilled workmen grow up.”
