Q460C hot rolled plate size and size list of NM450 sheet products specification: 6*2140*9000, 67*3098*5250, 25*1870*6460, 25*2400*5800, 6*1900*8700, 26*4355*6700, 11.9*1705*12000, 28*2250*12000, 6*2080*9800, 21*3098*4500, 12*2400*8000, 23.8*3260*11850, 6*2140*11600, 9.5*1690*3800, 12*1800*6000, 9*1850*8400, 6*2140*9000, 27.5*1850*12480, 22*1720*12380, 45*1800*6500, and 48*2600*5900(mm).

The final heat treatment of quenched and tempered alloy steel, size list of NM450 sheet is quenching and high temperature tempering. The hardenability of quenched and tempered alloy steel is high, and oil is generally used. When the hardenability is very high, it can even be air cooled, which can reduce the defects of heat treatment. The final properties of quenched and tempered alloy steel depend on tempering temperature. Generally, it is tempered at 500 ℃ - 650 ℃. The required properties can be obtained by selecting tempering temperature. In order to prevent the second kind of temper brittleness, fast cooling (water cooling or oil cooling) after tempering is beneficial to the improvement of toughness.

For the size list of NM450 sheet construction industry, the largest consumer sector of the steel industry and the least affected industry in the EU this year, it is estimated that size list of NM450 sheet steel consumption will account for 35% of the EU steel consumption market this year. Uestf forecasts that the output of the construction industry will decline by 5.3% in 2020 and rise by 4% in 2021.

In the final analysis, the market competition is the competition for customers. Whether selling products or services, the final customer satisfaction is the standard to test the success or failure of marketing work. The so-called after-sales service is to fully understand customers, study customer psychology, pay attention to after-sales details, improve work shortcomings, improve service quality, and Exchange customer brand loyalty through the whole process of quality service.

It can be predicted that in 2019, the national steel market quotation will not appear unilateral quotation, rebar size list of NM450 sheet steel main contract price of the largest shock range (the lowest price to the highest price), it is possible to reach as much as 1000 yuan this is the New Year's Chinese steel market quotation of the first characteristic. The second characteristic of Chinese steel market quotation in 2019 is that the average size list of NM450 sheet steel price of the whole year is roughly flat with the level of the previous year, or it is to rise somewhat, generally there will be no annual average price decline.
