Stainless steel offers numerous benefits over other alloys, including longer service life and lower maintenance costs. While this material can be a little more expensive to produce initially compared to other alloys, it can be very economical over time. Stainless steel is available in multiple types and grades to meet requirements for use in automotive, machinery, plumbing, mining, petrochemical, electrical industry, aerospace, submarine, railway, and others.
1.1 Austenitic Stainless Steel This type of casting is the most commonly used material, accounting for more than 70% of production. Grade 304 is the most commonly specified casting grade, with other popular austenitic grades including 316 and 317.
1.2 Ferritic Stainless Steel This type of casting involves a chromium stainless steel process, with the chromium content varying between 10.5 and 18% along with low carbon content.
1.3 Martensitic Stainless Steel This casting has a relatively high carbon content (0.1 – 1.2%) compared to other stainless steel casting types. Popular grades of this type include 410, 416, and 17-4.
1.4 Duplex Stainless Steel These stainless steels contain relatively high chromium levels (between 18 and 28%) and moderate amounts of nickel (between 4.5 and 8%)
