Introduction
Stainless steels are high-alloy steels which have high corrosion resistance than other steels owing to the presence of large amounts of chromium in the range of 4 to 30%. Stainless steels are classified into martensitic, ferritic and austenitic based on their crystalline structure. In addititon, they form another group known as precipitation-hardened steels, which are a combination of martensitic and austenitic steels.
The following datasheet will provide more details about grade 329H stainless steel, which has slightly lower alloy content than grade 2205, and is inexpensive.
