Quenching Improve the hardness of AH36 hull structure steel steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of AH36 hull structure steel steel and comprehensive mechanical properties.

The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of AH36 hull structure steel 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 AH36 hull structure steel steel, can be used as an alloying element of low alloy steel.

Training is one of the important factors in the construction of corporate culture. Online training system can be used to enable all employees to take advantage of fragmented time and carry out targeted training anytime and anywhere without the limitation of time and region. Through training to improve work skills, at the same time, through training, let all improve their quality education level, let employees work around a goal, create a career, and produce results.
