How to distinguish the normal floating rust and rusting of hot rolled 05CuPCrNi

Plate 20 to 30mm thick hot rolled 05CUPCRNI product: 20*1400*11400, 20*2100*7000, 20*2500*6200, 20*2933*7300, 20*3200*4400, 20.9*2851*7000, 21*2100*8810, 21.5*1630*13480, 22*3400*13000, 23.1*2590*7790, 25*1950*10150, 25*1950*9700, 25*2100*8400, 25*2100*8650, 25*2400*11600, 25*2400*8200, 28*2170*13000, 30*1600*10720, 30*1600*8600.

The overall intention of supporting prices in the raw material market is relatively strong, but the steel mills have a low acceptance of high prices, and some just need a small amount of goods, so the overall market game state is obvious. With the poor release of steel demand, terminal merchants tend to consume low-cost inventory in the early stage and purchase on demand to avoid the risk of large-scale hoarding. However, the cost side is weak, and some hot rolled 05CUPCRNI manufacturers secretly reduce prices to promote transactions. It is expected that the hot rolled 05CUPCRNI market will be stable and weak in the future.

Weathering steel is mainly used for steel structures exposed to the atmosphere for a long time, such as railways, vehicles, bridges, towers, photovoltaics, and high-speed projects. It hot rolled 05CUPCRNI is used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, and containers containing hydrogen sulfide corrosive medium in chemical petroleum equipment.

The hardness of the steel plate is very high, so special equipment is needed to complete the processing and cutting of these materials, hot rolled 05CUPCRNI. In order to cut the plate into an ideal size, the steel plate cutting needs to use natural gas flame for preheating, which will generate a large amount of oxygen flow during the operation. These substances will oxidize the steel plate, and then form a cutting edge, then the cutting operation process is basically completed. In the actual processing work, there are many different classifications for steel plate cutting.
