Description
Articles cast with molten iron are collectively referred to as iron castings. Due to the addition of chromium on the basis of iron, this product called High Chromium Iron Casting. The product is excellent in appearance quality, internal quality and use quality. Appearance quality refers to the surface roughness, surface defects, size deviation, shape deviation and weight deviation of the casting, specifically, whether there are holes and cracks inside the casting. The service quality refers to the working durability of iron castings under different conditions, including wear resistance, corrosion resistance, fatigue resistance and other properties, as well as technological properties such as machinability and weldability.
Importance
This High Chromium Iron Casting has a great impact on the performance of mechanical products. For example, the wear resistance and dimensional stability of machine tool castings directly affect the accuracy of machine tools; The size and surface roughness of impeller, housing and inner cavity of hydraulic components of various pumps directly affect the working efficiency of pumps and hydraulic systems; The strength and heat resistance of cylinder block, cylinder head, cylinder liner, piston ring, exhaust pipe and other castings of internal combustion engine directly affect the working life of the engine.
