E460(CC,DD,E) Low Alloy High Strength Steel

 

 

 

Here is the detailed information about E460 (CC, DD, E) Low Alloy High Strength Steel:

I.Naming Convention:

E: Stands for European structural steel (part of the Eurocode standard).

460: Indicates the minimum yield strength of the steel is 460 MPa, making it stronger than grades like E355 and E420.

CC/DD/E: Represent quality grades, differing in impact toughness requirements and impurity content. Higher grades (e.g., E) offer superior low-temperature resistance and purity.

II. Differences in Quality Grades (CC/DD/E)

Grade	Impact Test Temperature	Minimum Impact Absorption Energy (KV2, J)	Phosphorus (P) ≤ (%)	Sulfur (S) ≤ (%)
CC	+20°C	40	0.025	0.015
DD	-20°C	40	0.025	0.015
E	-40°C	27	0.020	0.010

 

III. Main Performance Characteristics

High Strength:

With a yield strength of 460 MPa, it is suitable for high-load structures (e.g., heavy machinery, long-span bridges), enabling material reduction and lightweight design.

Excellent Toughness:

CC: Suitable for normal or warm regions.

DD: Ideal for -20°C environments (e.g., northern regions).

E: Designed for extreme cold (-40°C), such as Northeast China, Northwest China, or high-altitude areas.

Weldability:

Controlled carbon equivalent (CEV) and alloy elements (e.g., Mn, Si, Nb, V) reduce cracking risk during welding, making it suitable for on-site fabrication of large structures.

Corrosion Resistance:

Alloy elements enhance atmospheric corrosion resistance, potentially reducing the need for anti-corrosion coatings in some applications.

 

 

 

 

 

 

IV. Typical Application Fields

Bridge Engineering: Main girders and pier support systems of large-span steel bridges.

Heavy Machinery Manufacturing: Frames for mining equipment, crane arms, and port machinery structures.

High-Rise Buildings: Steel frames and seismic support systems requiring high strength and toughness.

Energy Industry: Wind turbine towers, high-voltage transmission towers, and offshore oil platform structures (requiring low-temperature and corrosion resistance).

Low-Temperature Environments: Grade E plates are used in cold storage facilities, polar infrastructure, or industrial plants in frigid regions.
