 High Strength Structural Steel

 

 Definition:

High strength structural plates refer to welding low carbon structural steel.  Its carbon content is usually less than 0.25%, and have higher yield point or yield strength than the ordinary carbon structural plates. They have good hot and cold processing formability, good weldability, low brittleness susceptibility, gaps and aging sensitivity, and good corrosion resistance for atmosphere and seawater. The alloy element content is low, generally below 2.5%, which can be used in hot rolled or after heat treatment; The capacity of  high strength low alloy steel in the developed industrial countries accounted for about 10% of steel production.

 

Features:

The high strength structural plates not only have excellent weldability, but also have high strength and toughness. International leading mills have generally adopted ironstone smelting iron and its subsequent advanced steelmaking processing, and ensured that the content of residual elements in steel plate is very low.  They also have produced very great bending performance and machining properties, for the lighter weight but higher intensity. Then it can reduce the material consumption, also the cost of raw materials, welding and transportation.

More and more industries have chosen high strength structural plates to meet the both requirements-- high properties and low weight, so we have to promote these higher standard products for the more industries and customers.

In order to meet their different requirements on properties and price, CM will continuously expand the channels, and provide many kinds of high strength structural plates for customer option.
