Based in the industrial heart of Hamilton, Will Sheetsandplates has built a strong reputation as a trusted local source for high-performance metals. We are particularly proud to supply Duplex Steel S31803 Angle, a material that expertly balances strength and corrosion resistance. Sourced with care, our angles are the ideal choice for demanding projects where durability is non-negotiable, offering a reliable and cost-effective solution for engineers and fabricators across New Zealand who need a product that can truly stand the test of time.
The standout quality of Duplex Steel S31803 lies in its unique blended composition, which combines the strengths of both austenitic and ferritic steels. This mix creates a material with an impressive yield strength and excellent toughness, effectively resisting stress corrosion cracking. It also holds up remarkably well against pitting and crevice corrosion, especially in chloride-rich environments. Essentially, you get the best of both worlds: the easy fabrication often associated with austenitic grades, but with nearly double the strength, making for a wonderfully robust and long-lasting angle.
