This precision process allows us to produce complex and intricate shapes, minimizing the need for extensive secondary machining. Our components are trusted in critical applications across the energy, industrial, and agricultural sectors, where performance and reliability are non-negotiable.
Austenitic Stainless Steel Castings
Austenitic stainless steels are the most widely used family of stainless steels, valued for their excellent corrosion resistance, toughness, and non-magnetic properties. They typically contain chromium in the range of 16–26% and nickel between 8–22%, which gives them superior durability and performance in demanding conditions. These castings are highly suitable for aggressive environments such as marine, chemical processing, and food industries. Common Types of Austenitic Stainless Steel Castings are CF8 / CF8M (304 / 316 equivalents), CF3 / CF3M (304L / 316L equivalents), SS303 (CF16F) , SS317(CG8M)
Ferritic Stainless Steel
Ferritic stainless steels are known for their high resistance to stress corrosion cracking and good oxidation resistance. They generally contain 11–30% chromium with very little or no nickel, making them more cost-effective than austenitic grades. These castings are magnetic and offer moderate toughness with excellent resistance to chloride-induced corrosion. Ferritic stainless steels are commonly used in automotive components, industrial equipment, and applications requiring high-temperature oxidation resistance. Common types include CB30 (409 equivalent) and CC50 (446 equivalent).
Martensitic Stainless Steel
Martensitic stainless steels are distinguished by their high strength, hardness, and wear resistance, achieved through heat treatment. They typically contain 11–18% chromium and higher carbon content compared to other stainless steel families. While their corrosion resistance is lower than austenitic or duplex grades, they perform well in environments where mechanical strength is the primary requirement. Martensitic stainless steel castings are widely used in turbine blades, valves, pumps, and cutlery. Common types include CA15 (410 equivalent), CA40 (420 equivalent), and CB7Cu-1 (17-4 PH in quenched and tempered condition).
Precipitation Hardened Stainless Steel
Precipitation hardened (PH) stainless steels combine high strength with good corrosion resistance through a process of aging heat treatment. These alloys typically contain chromium and nickel, with additions such as copper, aluminum, or titanium to enable hardening. PH stainless steel castings offer an excellent balance of toughness, wear resistance, and mechanical properties, making them suitable for aerospace, chemical, and power generation industries. Common types include 17-4 PH (CB7Cu-1) and 15-5 PH, known for their strength and durability in critical applications.
Duplex Stainless Steels
Duplex stainless steels have a mixed microstructure of austenite and ferrite, giving them a unique combination of high strength and excellent corrosion resistance, particularly against stress corrosion cracking and pitting. They typically contain 18–28% chromium, 4–7% nickel, and additions of molybdenum and nitrogen for enhanced performance. Duplex stainless steel castings are ideal for marine, oil & gas, and chemical processing industries where both durability and resistance to harsh conditions are essential. Common types include CD4MCu (Alloy 2205 equivalent) and CE8MN (Alloy 2507 equivalent).
