Marine steel is widely used in all kinds of ships and offshore platforms, but it also puts forward higher and higher requirements for marine steel. In general, the demand share of EN 10025-6 high strength steel S460Q high-strength marine steel continues to increase. In terms of strength requirements, with the change of ship's large-scale, safety and coating specifications, the general trend is that the consumption of ordinary strength grade A marine steel plate is gradually reduced, and the consumption of high-strength marine steel plates is increased.

4140 steel is alloy structural steel, and its technical standard is ASTM A29/A29M. It belongs to ultra-high strength steel. EN 10025-6 high strength steel S460Q, 4140 steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after tempering treatment, and good low temperature impact toughness. 4140 steel is suitable for manufacturing large and medium plastic mould with certain strength and toughness.

Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This EN 10025-6 high strength steel S460Q rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.
