Heat-resistant steel casting
Material name: heat-resistant steel casting
Brand number: ZG35Cr26Ni12 Standard: GB 8492-87
● Characteristics and scope of application:
The highest use temperature is 1100℃, high temperature strength is high, antioxidant performance is good, adjust its composition within the range of specifications, can make the tissue contain some ferrite, can also be single-phase austenite. It can be widely used for many types of furnace components, but not for places where the temperature changes sharply
