Good quality Q345C carbon steel material with low cost

The ASTM/ASME SA516 Q345C carbon steel material specification covers carbon steel plates, which are mainly used for welding pressure vessels, where improving notch toughness is very important. The Q345C carbon steel material tensile strength range is 55-90MPa, and its versatility makes this specification very popular in applications.

Q345C carbon steel material, Weathering steel plate is a kind of common steel plate. For ordinary steel plate, if it is used for a long time, it will contaminate the steel surface with a layer of rust, which will seriously affect the normal use of steel. Although the weathering steel plate will produce rust, this layer of corrosion is like a layer of dense oxide film, which is firmly attached to the steel surface to prevent the further corrosion of the base and steel. There are many weathering steel plate manufacturers will adopt some corrosion treatment methods.

The advantage of hot-rolled stainless steel plate is that it can eliminate the damage caused by Q345C carbon steel material metal structure in the process of ingot casting to a certain extent, eliminate some tiny defects in the structure, refine the grains of stainless steel material, promote the structure of steel closer, and improve the performance of the material as a whole. This kind of lifting is mainly manifested in the rolling direction, which can make the Q345C carbon steel material steel no longer isotropic to some extent, and some defects such as bubbles, cracks and looseness formed during pouring can be eliminated under high temperature or high pressure.
