normalized CCS EH36 drilling vessel steel delivered to Philippines

The Shipbuilding steel plate can be divided into general strength normalized CCS EH36 drilling vessel steel structural steel and high strength structural steel according to its minimum yield point strength level.BBN supplies and exports 3 types of ship steel, Ordinary Strength Steel Plate, High-tensile Strength Steel Plate and normalized CCS EH36 drilling vessel steel Extra High-tensile Strength Steel Plate. All steel plate product can be manufactured according to Society LR, ABS, NK, GL, DNV, BV, KR, RINA, CCS, etc.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the normalized CCS EH36 drilling vessel steel metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between normalized CCS EH36 drilling vessel steel strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.

Our company's business departments are a group of excellent and hard-working employees, who constantly carry out knowledge updating and steel knowledge training every day, only to provide better and professional services to customers.

The effect of nitrogen (N) on the properties of normalized CCS EH36 drilling vessel steel and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in normalized CCS EH36 drilling vessel steel and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
