Stainless Steel Grade 434
Stainless steels are high-alloy steels. They have high corrosion resistance due to high chromium content of about 4-30%. They are classified into 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 has performance and chemistry similar to that of 430 stainless steel.
