The basic phases of SMA490AW, SMA490BW, SMA490CW steel grades, structural steel in the annealed state are ferrite and carbide. The alloy elements are dissolved in ferrite to form alloy ferrite, which depends on solid solution strengthening to increase strength and hardness, but at the same time reduce plasticity and toughness. The addition of alloying elements reduces the carbon content of the eutectoid point, which increases the proportion of pearlite in the structure and reduces the distance of the pearlite layer. This also increases the strength of the steel and reduces the plasticity.
SMA490AW, SMA490BW, SMA490CW steel grades product is a low-alloy high-strength steel that adds a small amount of alloying elements to general steel to make it have corrosion resistance in the atmosphere. Weathering steel has 2-8 times the atmospheric corrosion resistance of ordinary carbon steel, and the longer the service time, the better the corrosion resistance. In addition to excellent weather resistance, weathering steel also has excellent mechanical and welding functions.
