Stainless steels are high-alloy steels. They have high corrosion resistance due to high chromium content of
about 4-30%. They are classified in to three types such as ferritic, austenitic, and martensitic steels based
on their crystalline structure.
Grade 434 stainless steel contains added molybdenum to increase its corrosion resistance. It is has
performance and chemistry similar to that of 430 stainless steel.
