430 grade stainless steel (also known as AISI 430, Type 430, UNS S43000, SUS 430, or EN 1.4016 / X6Cr17) is one of the most widely used and cost-effective stainless steel grades in the world.
It belongs to the 400 series and is classified as a straight-chromium ferritic stainless steel — meaning its primary alloying element is chromium (16–18%) and it contains very little or no nickel.
Quick Definition in One Sentence
430 stainless steel is a low-cost, magnetic, ferritic stainless steel with good corrosion resistance in mild environments, excellent thermal conductivity, low thermal expansion, and high formability, but limited pitting resistance in chlorides.
Key Characteristics of 430 Grade Stainless Steel
|
Property / Feature |
Value / Description |
Why It Matters |
|---|---|---|
|
Family |
Ferritic (body-centered cubic structure) |
Magnetic, good heat transfer, low expansion |
|
Main alloy |
Chromium 16.00–18.00% |
Forms protective passive oxide layer |
|
Nickel content |
≤ 0.75% (usually < 0.50% or trace) |
No nickel = stable & lower price |
|
Density |
7.70 g/cm³ |
Lighter than 304 (8.00 g/cm³) |
|
Thermal conductivity |
≈ 26 W/m·K |
~60% higher than 304 — heats/cools faster |
|
Thermal expansion |
10.5 × 10⁻⁶/°C |
~35% lower than 304 — less warping |
|
Magnetic |
Yes — strongly magnetic in all conditions |
Easy handling, magnetic knife holders |
|
Corrosion resistance |
Good in mild atmospheres, fresh water, nitric acid |
Pits in chlorides/salt water |
|
Maximum service temperature |
815 °C intermittent / 760 °C continuous |
Good oxidation resistance |
|
Cost |
30–50% lower than 304 |
Price stability, high-volume use |

Most Common Real-World Uses of 430 Grade Stainless Steel
430 is one of the highest-volume grades globally because it performs well in mild conditions at low cost. Typical applications include:
Quick Summary – What “430” Really Means in Practice
When someone says “430 grade stainless steel”, they usually mean:
Bottom line: 430 is good quality and very widely used — not the highest corrosion resistance, but excellent value, thermal performance, and formability for most everyday uses.
