High - strength low - alloy mild - carbon steel plate is a type of engineering structural steel that is developed by adding a small amount of alloying elements to low - carbon steel. Here is a detailed introduction:

Definition

It refers to low - alloy engineering structural steels whose yield strength exceeds 275MPa in the rolled - or normalized - state. The total content of alloying elements in the steel is no more than 3%, which is why it is called "low - alloy". It has higher strength compared with carbon structural steels, so it is named "high - strength".

Composition Characteristics

Low - carbon: The carbon content is ≤0.20%, which is to meet the requirements of process performance such as plasticity, toughness, weldability, and cold deformation of engineering structural parts.

Low - alloy: On the basis of carbon structural steel, a small amount of alloying elements such as Mn, Si, and trace amounts of Nb, V, Ti, Al, etc. are added. Mn is the main alloying element, which not only has a significant strengthening effect on ferrite but also can reduce the cold - brittle temperature of the steel and increase the pearlite content in the steel to further improve the strength. Trace elements such as V, Ti, Nb, and Al can refine the grains, further improve the strength, and also improve the toughness of the steel.

Performance Characteristics

High strength: It is 30% - 50% higher than the strength of corresponding carbon engineering structural steels in the hot - rolled or normalized state, which can bear large loads, and is beneficial to reducing the self - weight of components, improving compactness and reliability, and saving raw materials and costs.

Good atmospheric corrosion resistance: The addition of a small amount of elements such as Cu, Ni, Cr, and P can effectively improve the ability of engineering structures to resist the corrosion of the atmosphere, seawater, and soil.
