Precautions for hardox 450 vs ar450 cutting
Composition characteristics of Hardox 450 vs ar450 product: (1) Low carbon: Due to high requirements for toughness, weldability and cold formability, its carbon content does not exceed 0.20%. 2) Add manganese-based alloying elements. 3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of the steel.
Slow heating, preheating and other balanced heating methods can be used to reduce the heat treatment deformation of wear-resistant composite plate. Correct heat treatment process and reasonable tempering heat treatment process are also effective methods to reduce the deformation of wear-resistant composite plate. There are many reasons for the deformation of wear-resistant composite plate, Hardox 450 vs ar450. We only need to master the deformation law and analyze the reasons. The deformation of composite wear-resistant plate, Hardox 450 vs ar450 can be alleviated and controlled.
Vanadium mainly exists in the form of carbide in Hardox 450 vs ar450 and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.
The "Plan" pointed out that by the end of December 2020, the steel production capacity in Tianjin will be controlled at about 15 million tons, and the steel production capacity in Hebei Province will be controlled within 200 million tons, and the elimination of the carbonization chamber with long furnace age and poor furnace condition will be accelerated. 4.3 Rice coke ovens promote the gradual withdrawal of independent coking companies. At present, there are 24 steel enterprises in Shanxi Province in need of transformation, of which 17 have been completed, and the remaining 7 enterprises are speeding up project-related finishing work.
