Great Wall Steel Casting Company Wear-resistant Steel Casting Introduce
2016-06-16 | Editor:
Wear-resistant steel casting is used for the casting of steel castings A cast alloy, with steel parts are made of steel castings, iron castings and similar performance, but better than cast iron strength. Carbon steel castings steel castings divided, low alloy steel casting and casting of special steel categories.
1.Carbon steel castings
Carbon as the main alloying elements and wear-resistant steel castings contain small amounts of other elements, carbon content less than 0.2% for casting low carbon steel, carbon 0.2% to 0.5% for the casting of steel, carbon content greater than 0.5% for the casting of high-carbon steel. With the increase of carbon content, increasing the strength of cast steel, increased hardness. Cast carbon steel with high strength, ductility and toughness, low cost, for the manufacture of parts to withstand large loads, such as base, door frames and other heavy machinery; and for the manufacture of large force and withstand the impact of parts such as vertical mill rocker arm, ball mill gear wheels and grinding roller .
2.low-alloy steel castings
Wear-resistant alloys containing elements manganese, chromium, copper and other cast steel. The total amount of alloying elements is generally less than 5%, with great toughness, and heat treatment through better mechanical properties. Low alloy steel casting than carbon steel has more excellent performance, can reduce part quality, increase service life.
3. special steel castings
In order to meet the special needs refining alloy steel, wide variety, usually containing one or more of the high amount of alloying elements to achieve a particular performance. For example, the ability of high-manganese steel manganese by 11% to 14% of impact wear, used for mining machinery, engineering machinery wear parts; various chromium or chromium-nickel stainless steel as the main alloying elements, for corrosion or 650 Part of the work at high temperatures ℃.
1.Carbon steel castings
Carbon as the main alloying elements and wear-resistant steel castings contain small amounts of other elements, carbon content less than 0.2% for casting low carbon steel, carbon 0.2% to 0.5% for the casting of steel, carbon content greater than 0.5% for the casting of high-carbon steel.
