hardox 450 steel wear resistance plate surface test

Hardox 450 steel wear resistance, Welded pipe plays an important role in modern industrial production and engineering construction, and has become one of the irreplaceable steel pipe products. Welded pipe is a kind of steel pipe made of rolled plate and steel plate after crimping and forming. Therefore, the diameter of welded pipe can be made very large and can be made according to the requirements of customers. Welded pipes can be used for water diversion, transportation of gas, air, oil and heating steam and other generally lower pressure fluids.

The secondary quenching and low temperature tempering of wear resistant composite plate are mainly used for high alloy steel workpieces without mechanical processing after carburizing. Carburizing, high-temperature tempering, one-time heating quenching, low-temperature tempering, quenching temperature 840-860℃, mainly used for Cr Ni alloy carburizing workpiece. The second quenching and low-temperature tempering of wear-resistant composite plate, Hardox 450 steel wear resistance mainly improves the microstructure of the infiltrated layer. When the requirements for core properties are not high, quenching can be performed between AC1 and AC3, and when the requirements for core properties are high, it should be quenched above AC3.

The basic principle of Hardox 450 steel wear resistance, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.

According to the monitoring of the Iron and Steel Association, at the end of October, the China Steel Price Index (CSPI) was 107.34 points, an increase of 1.24 points or 1.17% from the end of last year; the price of CIOPI imported iron ore during the same period was US6.38/ton, an increase of US.86/ton from the previous month, an increase of 28.57%. The price increase of iron ore is significantly greater than that of steel, and the impact on the production costs of steel companies will gradually become apparent, greatly reducing corporate profitability.
