Description of High Temperature Stainless Steel
High temperature resistant stainless steel is used for soft magnets and oxygen resistant powder high temperature resistant stainless steel furnace tubes. The maximum diameter can reach 1500mm and the thickness can reach 25mm. The length is more than 13 meters. It is not oxidized and deformed under the temperature of 1080 ℃ throughout the year.
Huaxiao high temperature stainless steel is designed for temperatures up to 1150 ° C. This durability is achieved by adding several important alloying elements to the steel, ensuring excellent performance in a wide range of stainless steel for high temperature applications. Its service life is 5 times that of traditional centrifugal casting pipes, and the price of stainless steel is 1/3 of similar imported products. 2/3 domestically produced.

The continuous and intermittent working temperature of stainless steel alloy
When setting the iron for an application to the heater, it is necessary to be aware that the wire may be exposed to heat for several minutes, minutes, an hour or more. . The short, periodic time is affected by leaving the oven to cool down is called intermittent, and the long-term placement in the oven is called continuous transmission.
The point is that metal shields can have different temperatures, depending on whether the transmission is constant or continuous. The following are some examples of continuous and intermittent stainless steel heat sinks:
304 Grade High Temperature Stainless Steel
Continuous: 1,700 ° F (925 ° C)
Intermittent: 1,600 ° F (870 ° C)
309 Grade High Temperature Resistant Stainless Steel
Continuous: 2,000 ° F (1,095 ° C)
Intermittent: 1,800 ° F (980 ° C)
310 Grade High Temperature Resistant Stainless Steel
Continuous: 2,100 ° F (1,150 ° C)
Intermittent: 1,900 ° F (1,025 ° C)
316 Grade High Temperature Stainless Steel
Continuous: 1,700 ° F (925 ° C)
Intermittent: 1,600 ° F (870 ° C)
347 Stainless Steel
347 stainless steel is equivalent to our country’s 0Cr18Ni11Nb stainless steel. Used for large boiler superheater
Pipes, reheater pipes, steam pipes, and petrochemical heat exchangers. The allowable anti-oxidation temperature used in the boiler tube is 750℃
410 Grade High Temperature Resistant Stainless Steel
Continuous: 1,300 ° F (705 ° C)
Intermittent: 1,500 ° F (815 ° C)
420 Grade High Temperature Stainless Steel
Continuous: 1,150 ° F (620 ° C)
Intermittent: 1350 ° F (735 ° C)
430 Grade High Temperature Resistant Stainless Steel
Continuous: 1,500 ° F (815 ° C)
Intermittent: 1,600 ° F (870 ° C)
You may have noticed a strange and inconsistent build in the 300 series of stainless steel listed here. In particular, you agree that using a constant temperature is more effective than using intermittent and limited temperatures. It is to be expected that exposing the metal to heat for a short period of time will result in less impact than over a longer period of time.
