430 Stainless Steel

430 stainless steel is a representative type of ferritic stainless steel. It has a high chromium content, usually 16.00%-18.00%, and has good corrosion resistance. It is a general-purpose steel and is widely used in home appliances, construction, automobiles and other fields. Wanzhi Steel stocks various sizes and types, including 430 stainless steel coils, 430 stainless steel plates and strips, and supports all surface processing, welcome to contact us for more information.

Features and Benefits

1. Corrosion resistance: Good corrosion resistance to a variety of media (including nitrates and some organic acids), especially when the surface is highly polished.

2. Oxidation resistance: Good oxidation resistance at 870°C intermittent operation and 815°C continuous operation.

3. Formability and ductility: 430 stainless steel plate is a non-hardenable ordinary chromium stainless steel with excellent finish and formability, and ductility.

4. Processing performance: Easy to cold work but not as tough as 304 stainless steel. 430 ss is often used for aesthetic applications, and the surface finish is very important.

Stainless Steel Usage

Is 430 stainless steel better than 316?

Both are available as food grade stainless steel. For example, a manufacturer that specializes in high-acid foods (such as tomato products) will have different needs than a manufacturer that produces baked goods. Therefore, the differences and advantages and disadvantages of them are as follows:

Heat Resistance

Both Grade 316 and Grade 430 resist oxidation at high temperatures. Of the two, Grade 316 performs better, with a continuous service temperature of 1472°F (800°C), while Grade 430 is suitable for intermittent temperatures of 1598°F (870°C) and continuous temperatures of 1499°F (815°C). However, Grade 430 becomes brittle after long-term use at 752-1112°F (400-600°C), requiring annealing to reverse this effect. In applications where stainless steel parts are frequently stressed, Grade 430 is more resistant to stress corrosion cracking.

Corrosion Resistance

Due to the same chromium content, both are highly resistant to organic acids and nitric acid. However, 316 has additional resistance to pitting caused by a wider range of acids, bases, and salts, while 430 has higher resistance to sulfur and oxidation. Overall, 430 is acceptable when exposed to acids only for a short period of time, while 316 can withstand long-term repeated exposure. In addition, 430 must be wiped immediately after exposure to moisture to avoid rusting and must be kept well-polished to maintain its functionality.

Cleaning ability

Both can be cleaned quickly and efficiently.
