| 
				 GH3030  | 
			
				 
  | 
			
				 0~ 1100 C  | 
			
				 Nickel-base superalloy steel, with excellent oxidation resistance and corrosion resistance, is usually used as heat-resistant steel.  | 
		
| 
				 quartz  | 
			
				 Si02  | 
			
				 0~ 1000 C  | 
			
				 Good heat shock resistance, but low strength; good acid resistance, poor alkali resistance, poor gas tightness in hydrogen and reducing gases  | 
		
(thermal response time refers to the time required for a thermocouple to change to 50% of its steady state value at step temperature, expressed in_0.5)
