· Manganese (Mn): ≤ 1.50%

· Phosphorus (P): ≤ 0.020%

· Sulfur (S): ≤ 0.010%

· Nickel (Ni): ≤ 0.70%

· Chromium (Cr): ≤ 0.30%

· Molybdenum (Mo): ≤ 0.10%

· Copper (Cu): ≤ 0.30%

· Niobium (Nb): ≤ 0.05%

· Titanium (Ti): ≤ 0.03%

· Vanadium (V): ≤ 0.05%

· Boron (B): ≤ 0.005%

Mechanical Properties

The mechanical properties of P460QL2 are characterized by high strength and excellent toughness, which are achieved through the quenching and tempering process. The typical mechanical properties are as follows:

· Yield Strength (ReH): ≥ 460 MPa

· Tensile Strength (Rm): 570 - 720 MPa

· Elongation (A): ≥ 17%

· Impact Energy (KV): ≥ 40 J at -40°C

Heat Treatment State

The P460QL2 steel plates are supplied in the quenched and tempered condition. This heat treatment process ensures that the steel has a fine-grained microstructure, which contributes to its superior mechanical properties and improved resistance to brittle fracture.

Low-Temperature Impact Test

P460QL2 is subjected to a low-temperature impact test to ensure its suitability for use in cryogenic conditions. The steel must demonstrate an impact energy of at least 40 joules at a test temperature of -40°C, which confirms its ability to withstand low-temperature environments without suffering from brittle failure.
