Helps to increase strength. Like manganese, silicon is used to maintain the strength of steel during the production of steel. Continuous cooling transformation curve of undercooled austenite in practical production, most of undercooled austenite transforms during continuous cooling, so it is necessary to measure and use the continuous cooling transformation curve of undercooled austenite. Most of the quenched and tempered parts are required to bear a variety of working loads, that is, they have high strength and good plasticity and toughness. Good hardenability is also required for alloy quenched and tempered steel. But the stress of different parts is different
1、 Hardox450 wear-resistant plate has complex stress conditions and requires high comprehensive mechanical properties.
2、 HARDOX wear-resistant plate for holding and holding the hardenability of different composition characteristics of carbon content
3、 Improve the strength of steel. For example, the properties of Cr steel after quenching and tempering treatment are much higher than those of steel; the elements to prevent the second kind of temper brittleness are added: alloy quenched and tempered steel containing Ni, Cr and Mn.
4、 The second kind of temper brittleness is easy to occur when tempering at high temperature and slow cooling. The addition of Mo and W can prevent the second kind of temper embrittlement.
5、 Make the core of parts have enough plasticity and toughness. The isothermal transformation curve of undercooled austenite in Zhuzhou is also called C curve.
6、 It is called austenitizing. () the winter of HARDOX wear-resistant plate plant will come later, and the growth rate of fixed assets investment in iron industry will drop obviously. Year month.
7、 450 wear resistant plate increased year on year.
8、 The combination method of setting water stop strip or water stop belt in the middle of joint is selected. V in polluted air (e.g. atmosphere with large amount of sulfide, carbon oxide and nitrogen oxide).
10、 Condensate will form acetic acid point.
