Weathering Steel NM600

Weathering Steel NM600

NM600 Benefits:

Features: wear-resistant and strong; Object: Specially used for large area wear condition.

tempered steel:

Medium carbon or low carbon structural steel is first cleaned and then tempered at high temperature to obtain higher strength and impact toughness and other better comprehensive mechanical properties of steel.

excellent wear resistance:

The chemical composition of the wear-resistant layer of the alloy carbon content of 4 ~ 5%, chromium content of 25 ~ 30%, the volume fraction of Cr7C3 carbide in the metallographic structure of more than 50%, the macro hardness of HRC56 ~ 62, the hardness of chromium carbide HV1400 ~ 1800. Because the carbide is vertically distributed in the wear direction, the wear resistance is more than doubled compared with the cast alloy with the same composition and hardness.

good impact resistance:

The substrate of the wear-resistant composite steel plate is low carbon steel or low alloy. Stainless steel and other ductile materials, reflecting the advantages of bimetal, wear-resistant layer to wear the wear of the medium, the substrate bears the load of the medium, so it has good impact resistance. Can withstand impact and wear such as high drop hoppers in material handling systems.

better heat resistance:

The wear-resistant layer of alloy is recommended to be used under conditions of ≤600℃. If vanadium, molybdenum and other alloys are added to the wear-resistant layer of alloy, it can withstand high temperature wear of ≤800℃. The recommended temperature is as follows: Ordinary carbon steel substrate is recommended to be used under conditions of no higher than 380℃; Low-alloy heat-resistant steel plate (15CrMo, 12Cr1MOV, etc.) is recommended for use under conditions not higher than 540℃; Heat-resistant stainless steel substrate is recommended for use under conditions not higher than 800 ° C.
