10 mm thickness hot rolled Q345D carbon steel plate sheet properties

We are a professional Q345D carbon steel plate sheet steel raw material supplier with a history of 17 years. After years of development, the company's steel plates and coils are widely used in construction, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and other fields around the world. With good product Q345D carbon steel plate sheet quality, we have solid project cooperation with foreign governments or leading enterprises such as Egypt, Bangladesh, Myanmar, Thailand, Philippines, Vietnam, Venezuela, Peru, Mexico, the United States, Portugal, Russia, Iran, Iraq, Pakistan, etc.

After heat treatment and cold drawing hardening, 65Mn steel has higher strength, certain toughness and plasticity; under the same surface state and complete hardening, the fatigue limit is equivalent to that of alloy springs. However, due to poor hardenability, it is mainly used for springs of Q345D carbon steel plate sheet smaller sizes, such as pressure regulating springs, force measuring springs, round and square spiral springs on general machinery or drawn into steel wires as springs on small machinery.

The Performance requirements of low alloy structural steel, Q345D carbon steel plate sheet:(1) High strength: generally, the yield strength is above 300Mpa.(2) High toughness: the elongation is required to be 15% - 20%, and the room temperature impact toughness is greater than 600kJ/m ~ 800kJ/m. For large welded components, higher fracture toughness is required.(3) Good weldability and cold forming property.(4) Low cold brittle transition temperature. (5) Good corrosion resistance.

As the thickness and hardness of Q345D carbon steel plate sheet increase, the tendency to crack at the cutting edge increases. In order to prevent the Q345D carbon steel plate sheet from cutting cracks, preheating should be carried out before Q345D carbon steel plate sheet cutting. Special attention should be paid to preheating to make the entire Q345D carbon steel plate sheet interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole Q345D carbon steel plate sheet cannot be preheated, the partial preheating method can be used instead.
