For many industries, alloy 430Ti is a popular choice of material due to its physical properties and mechanical properties. Even though it’s not as strong as some other alloys, it offers superior corrosion resistance and good formability. Let’s take a look at what exactly makes alloy 430Ti so special, and why it’s so widely used.
430TI Chemical Composition
Alloy 430Ti consists of iron (Fe) with small amounts of carbon (C), chromium (Cr), manganese (Mn), nickel (Ni), silicon (Si) and titanium (Ti). The addition of titanium in this alloy makes it highly resistant to corrosion. It also helps to make the material softer than stainless steel grades with similar chromium and nickel levels.

| Iron, Fe | 76 – 80 |
| Chromium, Cr | 16-19.5 |
| Manganese, Mn | 1 |
| Silicon, Si | 1 |
| Nickel, Ni | 0.8 |
| Titanium, Ti | 0.50 (min) |
| Carbon, C | 0.10 |
| Phosphorous, P | 0.04 |
| Sulfur, S | 0.03 |
430TI Physical Properties
The physical properties of SS 430Ti are excellent for many applications. It has a density of 7.8 g/cm3, which is slightly higher than stainless steel alloys with similar levels of chromium and nickel. Its melting point is 1380° C, making it suitable for welding applications requiring heat resistance. Additionally, this alloy has a relatively low thermal expansion coefficient, which makes it ideal for use in environments where temperature fluctuations occur frequently.
