What is the effect of chromium in cast iron?
What is the effect of chromium in cast iron?
Chromium improves the elevated temperature properties of grey iron. The aim of this experimental study is to study the effect of adding (2.11% chromium, 3% manganese and 2.02% silicon) to grey cast iron cast shells in order to improve the wear resistance of the surface.
Which cast iron process has higher hardness?
White cast iron has high compressive strength and retains good hardness and strength at a higher temperature. The presence of different carbides, depending on the alloy content, makes white cast irons extremely hard and abrasion resistant but very brittle.
Which type of cast iron is strongest?
Because of their austenitic matrix and with flake graphite, the high-nickel cast irons are the toughest of all cast irons. The flake graphite also gives them excellent machinability and good foundry properties, although this gives them lower tensile strengths.
Which cast iron has a higher tensile strength?
Compacted graphite iron
Compacted graphite iron has a higher tensile strength and improved ductility compared to gray iron.
What is high chrome iron?
High-chromium white iron is an erosion resistant ferrous alloy widely used in manufacturing, it has for long been applied to components in mining and minerals industry due to its excellent abrasion resistance, imparted by the hard alloy eutectic carbides present in the microstructure.
How do you increase tensile strength of cast iron?
Addition of Copper increases both tensile strength and hardness of gray iron.
What are the four basic types of cast iron?
The 4 Types of Cast Iron
- #1) Gray Cast Iron. The most common type, gray cast iron features a graphite microstructure consisting of many small fractures.
- #2) White Cast Iron. While not as common as gray cast iron, white cast iron is another type worth mentioning.
- #3) Ductile Cast Iron.
- #4) Malleable Cast Iron.
What are the four types of cast iron?
What is chrome iron used for?
Applications for Chrome White Iron Pumps, impellers and suction or bearing liners are some of the most common uses for chrome white iron. Chute liners, apron-feed liners, and gyratory crusher liners are very common uses in the mining industry.
What is high chrome alloy?
It is a high-nickel–chrome alloy with some iron content that has excellent corrosion resistance and high-temperature properties that is readily heat treated to obtain the required characteristics. From: Seals and Sealing Handbook (Sixth Edition), 2014.
