Heat resistance and working conditions of hard nickel castings

- Mar 31, 2019-

Hard nickel castings have good impact resistance when used. The base of wear resistant composite steel plate is low carbon steel or low alloy.Stainless steel and other ductile materials, reflects the superiority of bimetal, wear layer resistance to wear medium wear, substrate under the load of medium, so it has a good impact resistance.It can withstand the impact and wear of high drop hopper in the material conveying system.

 

Nickel hard casting good heat resistance, wear-resisting layer is recommended to use normally used under the working condition of 600 or less, if adding vanadium alloy layer, such as molybdenum alloy, can withstand the high temperature of 800 or less wear and tear.Recommended temperature is as follows: ordinary carbon steel substrate recommended is not higher than 380 condition of use;Low alloy heat-resistant steel plate (15 crmo, 12 cr1mov, etc.) recommended base plate is not higher than 540 condition of use;Heat resistant stainless steel substrates recommend used at not higher than 800 condition.

 

The alloy layer of good corrosion-resistant and wear-resisting ni-hard castings contains a high percentage of metallic chromium, so it has certain rust resistance and corrosion resistance.It can prevent coal from sticking when used in coal chute and funnel.Standard wear-resistant composite steel plate can be provided with 1200 or 1450 2000mm, or according to user demand, according to the size of the drawing customized processing.Wear-resisting composite steel plate is divided into three types: ordinary type, impact type and high temperature type.www.wuxiorient.com
