430 Stainless Steel Square Bar
Stellanox Steel supplies durable and cost-effective 430 Stainless Steel Square Bars, ideal for applications where formability, oxidation resistance, and aesthetic appeal are important. As a ferritic stainless steel grade, 430 square bars are magnetic, corrosion-resistant in mild environments, and widely used in indoor structural elements, kitchen appliances, and decorative components.
This bar is a reliable, economical alternative to austenitic grades like 304 when extreme corrosion resistance is not required.
What is 430 Stainless Steel Square Bar?
430 Stainless Steel Square Bar is a ferritic stainless steel alloy containing 16–18% chromium. It offers good corrosion resistance in indoor and mildly corrosive conditions and exhibits excellent oxidation resistance at elevated temperatures. Unlike 300-series stainless, 430 is magnetic and non-hardenable but has good mechanical strength and polishability.
430 square bars are frequently chosen for decorative, automotive, and industrial fabrication purposes where cost and performance must be balanced.
