Forming and corrosion resistance of alloy steel castings
Aug 17, 2018

In the process of making alloy steel castings, liquid metal is mainly cast into the casting cavity corresponding to the shape of the part. After cooling and solidifying, the method of obtaining or blank can be obtained.Metals (ferrous metals such as iron, steel, stainless steel, alloy steel, etc.Non-ferrous metals such as copper, aluminum, tin, lead, zinc, magnesium, titanium, etc.It is divided into sand casting, metal gravity casting, ceramic or gypsum gravity casting, shell casting, epc casting, special casting and so on.

 

Strength of alloy steel castings

 

The yield point of alloy steel castings determines the stress that the structure can withstand without permanent deformation, while the small yield point of typical low-alloy high-strength steel is 345MPa.Therefore, the allowable stress of low alloy and high strength steel is 1.4 times higher than that of carbon structural steel according to the proportion of yield point.

 

Forming properties of alloy steel castings

Alloy steel castings in its operating carbon structural steel, the high strength low alloy steel in general can undertake the processing, such as shearing, 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.

 

Corrosion resistance of alloy steel castings

 

The atmospheric corrosion resistance of low alloy and high strength steels changes with the composition and content of alloy elements that play a big role in corrosion resistance. The elements that improve the atmospheric corrosion resistance are copper, phosphorus, silicon, chromium, nickel and molybdenum.http://www.wuxiorient.com/
