Strength requirement and corrosion resistance of alloy steel casting
Jul 21, 2018

The strength of the alloy steel castings, the steel structure of the yield point to a certain extent, determines the structure are not permanent deformation stress, under normal circumstances the typical small carbon structural steel yield point is 235 mpa, typical small yield point of high strength low alloy steel is 345 mpa. Therefore, the allowable stress of high strength steel with low alloy is 1.4 times higher than that of carbon structural steel according to its yield point ratio.

 

Formability, alloy steel castings in production process of the high strength low alloy steel in general can conduct such processing and cutting, punching and machining, although its high yield point, even forming deformation is quite severe operation also can be used for forming of carbon structural steel cold bending punching machine, drawing machine, pressing machine and other equipment, but some equipment need to be modified.

 

Corrosion resistance of alloy steel castings, in the operation of the high strength low alloy steel with atmospheric corrosion resistance will be effective for corrosion resistance of alloy element in one of the big group and content, so that it can effectively improve the atmospheric corrosion resistance of elements are copper, phosphorus, silicon, chromium, nickel and molybdenum.

 

The casting mould of alloy steel casting can be used repeatedly. Every time metal liquid is poured, the casting can be obtained. The life is long and the production efficiency is high.Metal casting not only has good dimension precision and smooth surface, but also its casting strength is higher than that of sand casting and it is not easy to be damaged when the same metal liquid is poured.http://www.wuxiorient.com/
