2.Grade and Property for Cast Iron Steel 

Material	Grade	Mechanical Property		Features
		Harsness (HB)	Tensile Strength N/mm2)
Gray Cast Iron	LZ/HT200	150-210	≥180	High density Oil resistance Good processing performance
	LZ/HT250	160-230	≥220
	LZ/HT300	190-260	≥260

3.Application for Cast Iron Steel 
Gray Cast Iron can be used for pump shells, containers, towers, flanges, packing box bodies and glands, carbonization towers, nitrification towers , machine beds, columns, cylinders, gears and surface quenching parts.
Due to its resistance to deformation by heat, So it is also used in high temperature environments.

5.Advantages of our Cast Iron
1. The material is particularly pure, without defects such as sand inclusion, slag inclusion, and pores.
2. The comprehensive mechanical properties are high, especially the toughness and fatigue resistance are significantly improved: using Φ30-140 profiles, the speed is 3400r/min, and the average fatigue ratio is 48.2-67.9%, which can greatly improve the life of moving parts.
3. Uniform organization and excellent pressure resistance and density: using Φ130-160 profiles, the test cycle is 20min, the central part is 1.1mm thick, the pressure resistance is 65MPa without leakage, the outer part is 0.75mm thick, and the pressure resistance is 65MPa without leakage.
4. The hardness of the profile is evenly distributed, the relative hardness is low, and the machining performance is excellent.
5. High dimensional accuracy, small machining allowance, and high machining surface finish.
6. In addition to all the characteristics of the above profiles, the hollow cast iron profile products have further improved density uniformity and pressure resistance and density.
