Custom Stainless Steel Casting Manufacturer
Neocast Alloys is a premier custom stainless steel casting manufacturer in India. Producing flawless CF8M, 316L, and Duplex components for highly corrosive and high-temperature environments.
Our Stainless Steel Grades
As a comprehensive custom alloy casting foundry, we pour specialized stainless grades for diverse industrial requirements.
Austenitic
Martensitic
Duplex
Precipitation Hardening

Mastering Corrosion Resistance
Industries like food processing, marine, and chemical manufacturing demand components that will not degrade. As India's leading custom stainless steel casting manufacturer, we provide the solution.
Stainless steel is notoriously difficult to machine due to its hardness and work-hardening properties. By utilizing the investment casting process, we deliver near-net-shape precision steel castings with an excellent surface finish (Ra 3.2-6.3), drastically minimizing expensive secondary machining.
From CF8M valve bodies to Duplex marine hardware, our ISO certified foundry ensures exact metallurgical chemistry using state-of-the-art spectrometry.
Frequently Asked Questions
Q.What stainless steel grades do you cast?
As a specialized custom stainless steel casting manufacturer, we pour a wide variety of grades including Austenitic (304, 316, 316L), Martensitic (410, 420), Duplex (CD4MCU), and Precipitation Hardening (17-4PH) steels.
Q.Why choose investment casting for stainless steel?
Stainless steel is notoriously difficult and expensive to machine. Investment casting allows us to create near-net-shape components with a smooth surface finish, drastically reducing the amount of post-casting machining required.
Q.Do you supply food-grade stainless steel castings?
Yes. We cast highly corrosion-resistant CF8M (316) and CF3M (316L) stainless steel, which are standard for food and beverage processing equipment and pharmaceutical machinery.
Q.Can you guarantee the chemical composition of your stainless steel?
Absolutely. Every heat is analyzed using an advanced Optical Emission Spectrometer (OES) before pouring to ensure the alloy chemistry perfectly matches ASTM/ASME standards. We provide full EN 10204 3.1 certification.
