Where is 430 commonly used?

In automotive, household appliances, and decorative applications where cost and formability are important.

Is 430 stainless steel magnetic?

Yes, it is fully magnetic in all conditions.

Why is 430 cheaper than 304?

Because it does not contain nickel, which lowers cost but also reduces toughness and corrosion resistance.

Description

430 Stainless Steel is a ferritic stainless steel containing 16–18% chromium.It offers good corrosion resistance in mildly aggressive environments and excellent resistance to oxidation at elevated temperatures. While it cannot be hardened by heat treatment, it is magnetic and provides good formability, making it widely used in automotive trim, appliances, and architectural applications.

Introduction to Stainless Steel 430

What

Stainless Steel 430 (UNS S43000) is a low-cost, ferritic stainless steel that contains chromium as its main alloying element. It provides moderate corrosion resistance, good ductility, and oxidation resistance up to 815 °C (1500 °F). It is less expensive than austenitic grades like 304 because it contains no nickel, but this also limits its toughness and corrosion resistance in chloride-rich environments. It is fully magnetic and easy to form and polish, making it a popular choice for decorative and structural uses.

Advantages

Cost-effective, nickel-free stainless steel
Good corrosion resistance in mild environments
Excellent resistance to oxidation at high temperatures
Magnetic, with good polishability and formability

Applications

Automotive trim and exhaust parts
Kitchen appliances (refrigerators, dishwashers)
Architectural panels and decorative elements
Industrial equipment requiring moderate corrosion resistance
