Will JIS G3106 SM520C steel equivalent astm peel after rusting

In terms of steel for offshore platforms, steel also plays an important supporting role. Because the offshore platform is immersed in sea water for a long time, it also needs to withstand the test of various harsh sea conditions such as storms, waves, glaciers, etc. Therefore, the steel JIS G3106 SM520C steel equivalent astm for offshore platforms requires not only high strength, but also good corrosion resistance, low temperature toughness and resistance, lamellar tearing performance, etc.

According to the latest statistics of alacero, the consumption of finished steel JIS G3106 SM520C steel equivalent astm products in Latin America in 2019 was 64.2 million tons, down 5% from 67.6 million tons in 2018. The decline in steel consumption in the region reflects the economic contraction of Latin American countries, especially the three major economies: Mexico, Argentina and Brazil.

After adding a small amount of niobium, vanadium and titanium to JIS G3106 SM520C steel equivalent astm etc. steel, it is combined with the controlled rolling process to control the precipitation behavior of microalloying elements to achieve the purpose of improving the comprehensive properties of the steel, whether it is strength, toughness, ductile-brittle transition temperature, or Steel's process formability, welding performance, corrosion resistance and crack resistance have been significantly improved, while reducing production costs. Such steel products are widely used in oil and gas pipelines, vehicles, building structures, oil production platforms, pressure vessels, ship shells and many other fields.

The Brazil steel is facing a "crisis of demand" as the epidemic of new crown pneumonia spreads in Brazil. The demand for JIS G3106 SM520C steel equivalent astm and so on steel will be reduced by 50% in April. The demand for the second quarter will be 40% lower than that in the first quarter. The demand for this year will be reduced by 20% compared with the same period this year. In 2019, Brazil's apparent steel consumption was 20.6 million tons, a year-on-year decrease of 2.7%; crude steel production dropped to 32.33 million tons, the lowest since 2016 (30.2 million tons).
