Weather-resistant steel plate is a low-alloy steel series between ordinary steel and stainless steel. Weather-resistant steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. Forming, welding and cutting, abrasion, high temperature, fatigue resistance and other characteristics; weather resistance is 2 to 8 times that of ordinary carbon steel, and paintability is 1.5 to 10 times that of ordinary carbon steel.
On the supply side, the price of coke is high, and the enthusiasm of coke companies to start is high. The sample coke companies started 71.74%, 1.08% from the previous quarter, but due to the source of raw coal, the release of production is limited.
Compared with stainless steel, weathering steel has only a small amount of alloy elements, such as phosphorus, copper, chromium, nickel, molybdenum, niobium, and titanium. The total amount of alloy elements is only a few percent, unlike stainless steel, which reaches 100%. A dozen, so the price is relatively low.
Market: The market price has risen and demand has not followed up, but the fundamentals and bi-joule support are strong. It is expected that the cold-rolled price consolidation will be stronger tomorrow.
Weathering steel is a steel system that can be thinned, used, or simplified to paint, which can make products corrosion-resistant and prolong life, save labor, reduce consumption, and upgrade. It is also a steel system that can be integrated into modern metallurgical new mechanisms, new technologies, and new processes. And innovative steel system.
Most domestic weathering steels are used for painting, and the original design intention of no-painting and "rust prevention" has not been used.
Due to the characteristics of rust resistance, no painting, thinning and consumption reduction, labor saving and energy saving, it can be applied to steel structures such as buildings, vehicles, bridges, towers, etc. that have been used in the atmosphere for a long time, and can also be used to manufacture containers and railway vehicles , Oil derricks, seaport buildings, oil production platforms and other structural parts.
, Q235NH weather-resistant steel plate Q235NH full name: atmospheric corrosion-resistant hot-rolled steel, also known as Corden steel, corrosion-resistant steel, widely used in: outdoor steel for containers, power plant chimneys, railway engineering, such as large outdoor sculpture steel, weather-resistant steel is between The low-cost low-alloy steel series between ordinary steel and stainless steel can be developed and innovated after incorporating modern metallurgical new mechanisms, new technologies and new processes, and is one of the super-steel technology-leading series steel types.
02 | Supply-side reform continues to increase With the improvement of environmental protection, the output of intermediate frequency furnaces has been significantly compressed. The large withdrawal of ground steel has made the overall supply somewhat, and the profits of blast furnace plants have also improved.
First, every time the S-shaped economy has a long-term L-shaped downward channel, changing it to a J-shaped upward channel is reversed by a breakthrough and vigorous reform and opening up.
The steel has the characteristics of rust resistance, corrosion resistance, longevity, thinning and consumption reduction, labor saving and energy saving, and benefits the component manufacturers and users.
