What is the yield strength of spa-h corten steel

At the same time of doing well in spa-h corten steel production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the spa-h corten steel technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.

BBNsteel is one of the world-leading suppliers of construction steels for a global industry. We understand the unique demands of spa-h corten steel building large scale structures in an increasingly budget-conscious economy. Construction steel plates and steel sections are used from the ground up; particularly in civil engineering and large-scale industrial projects. Pilings and baffles are used to lay the groundwork and establish a strong foundational anchor for tall structures like skyscrapers.

As a new type of coil material, compared with the traditional steel coil, spa-h corten steel, the alloy steel coil and sheet has a great improvement in performance properties. The alloy steel coil and sheet has good thermal strength and oxidation resistance at high temperature. Moreover, the corrosion resistance of alloy steel coil and sheet is better. After long-term corrosion, the service life of traditional coil plate will decrease rapidly, but the new type coil, the alloy steel coil and sheet has strong corrosion resistance, and its service life is far longer than that of traditional coil plate.

Corrosion resistance of stainless steel mainly owes to the formation of a very thin, adhesive and translucent chromium oxide film on the surface of stainless steel. Once the film is damaged, the chromium in the stainless steel will react with oxygen in the atmosphere to restore the film quickly. At the same time, the mechanical damage can also generate a protective film quickly to prevent the spa-h corten steel, stainless steel from corrosion.

spa-h corten steel, No. 20 steel belongs to high-quality carbon steel.No. 20 steel means steel with an average carbon content of 0.20%;The thermal conductivity of No. 20 steel at 315℃ is 48 W/m℃;No. 20 steel is generally not quenched, the general treatment method is carburizing or normalizing;The yield strength of No. 20 steel is not less than 250MPa;The tensile strength of No. 20 steel is not less than 420MPa;Elongation of No. 20 steel is not less than 25%;The reduction of area is not less than 55%;The density of spa-h corten steel and No. 20 steel is 7.85kg/cm3
