430 Stainless Steel Bar: Magnetic, Low-Cost & Where to Buy

Want a magnetic, cost-effective stainless bar for indoor and decorative parts? 430 stainless steel bar delivers good corrosion resistance at a fraction of the nickel cost. This guide covers its properties, sizes, pricing and how to buy it well.

Why Choose 430 Stainless Steel Bar

430 is a ferritic grade (ASTM A276) with 16–18% chromium and no nickel. It is magnetic, polishes to a bright finish, and resists atmospheric and mild industrial corrosion at low cost. It is not for welding-heavy or marine duty, but it is ideal for decorative, architectural and lightly stressed parts.

Sizes, Shapes & Surfaces

We supply 430 bar as round (3–200 mm), square, hexagonal and flat, in lengths of 3000–6000 mm. Conditions include annealed, bright-drawn, peeled / turned or polished. Pickled and bright finishes suit tight-tolerance machined and decorative components.

430 Bar Price Factors

With no nickel, 430 is one of the cheapest stainless bars. Price moves with chromium content, diameter and condition; ground and polished bars cost more than black bar. Standard sizes ship fastest from our 100,000-ton stock.

Typical Applications

Decorative trim, architectural hardware, appliance parts, automotive trim, fasteners, and indoor structural and ornamental fabrications. Its bright finish and magnetism suit visible and magnetically aware assemblies.

How to Choose a Supplier

Confirm the ferritic chemistry and condition on the MTC, match the finish to the end use, and verify straightness. A stocked, ISO/TS16949-certified supplier with cut-to-length and fast lead time keeps your production line moving.
