What temperature can stainless steel withstand? Or the melting point of stainless steel is set when this material is being widely used in the industrial construction industry.
316 stainless steel is an austenitic stainless steel containing two chromium-nickel and 3% molybdenum. The molybdenum component increases corrosion resistance, improves pitting resistance in chloride ion solutions, and increases strength at elevated temperatures.
Stainless steel has different grades according to the composition content. Each type is applied in different fields accordingly. Let's update the melting temperatures of some of the following stainless steels:
- Melting temperature of stainless steel 201: From 1149 - 1232 degrees Celsius °C (2552-2642 °F)
- Melting temperature of 304 stainless steel: From 870 - 925°C (2552-2642°F)
- Melting temperature of 316 stainless steel: From 870 - 925°C (2507-2552°F)
- Melting temperature of 430 stainless steel: From 815 - 870°C (2597-2750°F)
- Melting temperature of 434 stainless steel: From 1426-1510°C (2600-2750°F)
- Melting temperature of 420 stainless steel: From 735 - 620 °C (2642-2750 °F)
- Melting temperature of 410 stainless steel: From 815 - 705°C (2696-2786°F)
With the temperature range updated above, we only calculate the relative. However, in everyday life, this parameter is not so important. Among the types of stainless steel above, we most often use 3 types including stainless steel 304, 202 and 430.
In terms of corrosion resistance, these 3 types have the following characteristics:
- 304 stainless steel: 304 stainless steel has good corrosion resistance in many different environments. Under normal conditions you will not need to worry, even in an environment with chemicals there is no problem. Therefore, 304 stainless steel is selected for the production of medical equipment.
- Stainless steel 202: Stainless steel 201 has a lower corrosion resistance than both 304 and 430 stainless steels. This grade is only resistant to corrosion in medium and mild environments.
430 Stainless Steel: This stainless steel is resistant to corrosion in organic acids and nitric acids. In addition, this type is also resistant to corrosion in mild environments. However, with the condition that there must be strict control of environmental impacts.
In terms of heat resistance, stainless steel has different levels of heat resistance as we mentioned above. Specifically, these 3 types differ as follows:
- 304 stainless steel: This type has the ability to withstand heat up to 925 degrees Celsius. However, it must be a constant temperature to melt this type of stainless steel. Under normal conditions, such as cooking, there is no effect.
- Stainless steel 202: This type has heat resistance from 1149 degrees Celsius to 1232 degrees Celsius. The highest among the 3 types of stainless steel.
- 430 stainless steel: This type has heat resistance from 815 degrees Celsius to 870 degrees Celsius. The lowest among the 3 types.
Machinability
In terms of machinability, these 3 types of stainless steel are studied as follows:
- 304 stainless steel: This type of stainless steel can be processed for all welding methods.
- 201 stainless steel: This grade is capable of performing machining with basic welding methods without problems. Both 201 and 304 stainless steel are easy to machine, making them the most popular on the market.
- 430 stainless steel: This type requires more difficult machining conditions than the above two types. Stainless steel 430 will have to be heated to the appropriate temperature before it can be machined. Suitable temperature will be from 150-200 degrees Celsius.
In terms of magnetism, the safety characteristics of the types are as follows:
- 304 stainless steel: This type is not magnetized or if there is, it will be very little and not affected.
- 201 stainless steel: This is a mild magnetism.
- 430 stainless steel: This type has a high magnetism.
The physical properties and heat resistance of 304 stainless steel are the factors that make this metal material increasingly chosen and have wide applications in today's life.
