Steel plate for marine ocean energy source equipment and preparation technique thereof

Abstract

The invention discloses a steel plate for marine ocean energy source equipment and a preparation technique thereof. The steel plate is composed of the following chemical components in percentage by mass: 0.21-0.33% of carbon, 0.55-0.85% of silicon, 0.15-0.22% of aluminum, 0.001-0.002% of boron, 1.00-1.45% of chromium, 0.55-0.75% of manganese, 0.009-0.013% of phosphorus, 0.002-0.005% of sulfur, 2.5-3.5% of molybdenum, 0.05-0.1% of niobium, 0.08-0.15% of vanadium and the balance of iron and inevitable impurities. The steel plate for ocean energy source equipment is composed of the carbon, silicon, aluminum, boron, chromium, manganese, phosphorus, sulfur, molybdenum, niobium, vanadium and iron according to specific proportioning, is especially suitable for long-term use in the ocean environment, effectively avoids cracking, and has favorable toughness and corrosion resistance.

Description

technical field

[0001] The invention relates to a steel plate, in particular to a steel plate for marine energy equipment and a preparation process thereof, belonging to the technical field of new energy. Background technique

[0002] Ocean energy is a kind of renewable energy stored in the ocean, including tidal energy, mechanical energy and thermal energy caused by waves. Ocean energy also involves a wider category, including wind energy over the sea, solar energy on the surface of sea water and biomass energy in the sea. China has 18,000 kilometers of coastline and 6,960 islands with a total area of ​​6,700 square kilometers. Most of these islands are far from land and thus lack energy supplies. Therefore, in order to realize the sustainable development of my country's coast and island economy, we must vigorously develop my country's ocean energy resources.

[0003] Ocean energy refers to the renewable energy attached to seawater. The ocean receives, stores and distrib...
