stainless-steels-composition
1. Corrosion resistance: Good corrosion resistance to a variety of media (including nitrates and some organic acids), especially when the surface is highly polished. In addition, it has excellent resistance to nitric acid corrosion, which is very suitable for chemical applications.
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 stainless steel is often used for aesthetic applications, and surface finish is very important.
430 stainless steel is widely used in the following fields because of its good corrosion resistance and versatility, as well as its excellent surface brightening effect:
Architectural decoration: such as doors and windows, railings, escalators, etc.
Fuel burner parts: due to its high temperature resistance and corrosion resistance, it is suitable for key parts of fuel burners.
Household appliances: such as automatic washing machine drums, stainless steel kettles, stainless steel pots, dishwashers, range hoods, solar water heaters, etc., are favored because they are safe, non-toxic and easy to clean.
Daily necessities: button batteries, watch cases, mobile phone cases.
Medical equipment: trays, scalpels, medical carts, tweezers, etc.
Stainless Steel Usage
In addition, 430 stainless steel is also used to make hot water tanks, hot water supply systems, sanitary appliances, bicycle flywheels, etc.
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:
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.
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.
Both can be cleaned quickly and efficiently.
