A633GrD steel plate is suitable for normalized high-strength low-alloy structural steel plate for tower connection or source bolt connection structure. A633GrD steel plate should be normalized: heat the steel plate to a suitable temperature that can produce austenite structure but does not exceed 1700F [925℃], and keep it at this temperature for a period of time, so that the entire SA283 Gr C mild steel carbon equivalent plate can be uniformly heated, and then left in the air Cool with medium.
The SA283 Gr C mild steel carbon equivalent plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The SA283 Gr C mild steel carbon equivalent products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.
The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of SA283 Gr C mild steel carbon equivalent nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of SA283 Gr C mild steel carbon equivalent steel, can be used as an alloying element of low alloy steel.
