P355GH vs p355nh, Special thick steel plate cutting needs to be preheated in advance. Some steel plates are prone to cracks after entering the cutting process, sometimes that is because the temperature is too low, and it is necessary to perform pre-heat treatment in advance for such cases. The staff can preheat the steel plates first, so that the temperature of the steel plates will gradually increase, and then the flame gun can be used to cut. The probability of cracks in the cut material is very low, and the quality of the steel plate is also guaranteed.

p355gh vs p355nh, 14Cr1MoR is a kind of alloy structural steel, which is a special steel for pressure vessel. 14Cr1MoR plate belongs to CrMo hydrogen resistant steel. Electric furnace + LF / VD refining method is adopted. 14Cr1MoR plate chemical elements:C: 0.05%-0.17% Si: 0.50%-0.80% Mn: 0.40%-0.65%P: 0.010%-0.012% Cr: 1%-1.5% Mo: 0.45%-0.65% Ni: 0.20%-0.25%14Cr1MoR steel equivalent grades are 4Cr13, SA387gr11cl2, 2.25Cr-1Mo, etc.

The data shows that Southeast Asia is the main p355gh vs p355nh and so on steel export region of China, and the steel export volume of Asia in 2019 is 37.198 million tons; that of North America and South America is 4.0678 million tons, and that of Europe is 1.1358 million tons. According to the latest epidemic data, South Korea and Japan are the most affected countries in Southeast Asia. However, the growth rate of the number of confirmed cases slowed down significantly, while the situation of the epidemic in Italy, a major European steel export country, was still severe, with the number of confirmed cases exceeding 53000. Therefore, the recovery speed of European market is slower than that of Southeast Asia.
