Comparison with GH4080A and GH4049:
Compared to GH4080A and GH4049, GH4033 has a lower operating temperature range and differs in ingredient content. GH4080A is suitable for working environments below 800 degrees Celsius, GH4049 is suitable for working environments below 950 degrees Celsius, and GH4033 is suitable for working environments below 700-750 degrees Celsius. In addition, there are differences in the content of the three components, so the specific operating temperature and performance requirements need to be considered when choosing the right material.
