THE COST‑EFFECTIVE SOLUTION
200 Series
Lower‐nickel, high‐manganese chemistry cuts raw‐material costs by up to 30% versus 300‑series, without sacrificing yield strength.
Excellent formability and good corrosion resistance ideal for bending, deep‐drawing and light structural parts.
Perfect for decorative trim, shelving, kitchen equipment and automotive molding where budget and appearance both matter.
The All rounder SOLUTION
300 Series
Enhanced hight temperature strength, ideal for use in environments over 500°C
High Carbon Content improves creep resistance and structural integrity under thermal stress.
Suitable for heat exchangers & boilers performs well in pressure vessels and other heat-intensive applications.
THE DURABLE SOLUTION
400 Series
Ferritic, magnetic grade with outstanding resistance to stress‐corrosion and oxidation in mild environments.
Good formability and surface finish—suited to appliance panels, architectural accents and food‑service fixtures.
Can be cold‑worked or heat‑treated for increased hardness and wear resistance in structural or wear‑component applications.
