EN10028-6 P500QH is a pressure vessel steel grade that is widely used in the fabrication of pressure vessels and boilers. It is a high-strength quenched and tempered steel plate designed to operate at low temperatures, making it suitable for applications where resistance to brittle fracture is crucial.

Chemical Composition:

The chemical composition of P500QH is strictly controlled to ensure the necessary mechanical properties and weldability. The typical chemical composition is as follows:

· Carbon (C): ≤ 0.16%

· Silicon (Si): ≤ 0.50%

· Manganese (Mn): ≤ 1.60%

· Phosphorus (P): ≤ 0.020%

· Sulfur (S): ≤ 0.010%

· Nickel (Ni): ≤ 0.80%

· Chromium (Cr): ≤ 0.30%

· Molybdenum (Mo): ≤ 0.10%

· Niobium (Nb): ≤ 0.05%

· Titanium (Ti): ≤ 0.03%

· Vanadium (V): ≤ 0.05%

· Boron (B): ≤ 0.005%

Mechanical Properties:

The mechanical properties of P500QH are characterized by its high strength and excellent toughness, which are achieved through quenching and tempering processes. The typical mechanical properties are as follows:

· Yield Strength (ReH): ≥ 500 MPa

· Tensile Strength (Rm): 590 - 770 MPa

· Elongation (A): ≥ 17%

· Impact Energy (KV): ≥ 40 J at -40°C

Heat Treatment State:

P500QH is supplied in a 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 toughness.

Low-Temperature Impact Test:

The steel is subjected to a low-temperature impact test at -40°C to ensure that it maintains its toughness and impact resistance at low temperatures. This is a critical requirement for materials used in pressure vessels operating in cold environments.
