HP265 gas cylinders steel plate

HP265 is a steel grade specifically designed for the manufacturing of gas cylinders. It falls under the GB/T 6653 standard, which specifies the technical requirements for hot-rolled steel plates, sheets, and strips used in welded gas cylinders.

Properties of HP265 steel:

Chemical Composition: The typical chemical composition of HP265 steel includes carbon (C) ≤0.20%, silicon (Si) ≤0.35%, manganese (Mn) ≤1.00%, phosphorus (P) ≤0.025%, sulfur (S) ≤0.015%, and additional trace elements such as aluminum (Al), titanium (Ti), and niobium (Nb).

Mechanical Properties: HP265 steel generally has a minimum tensile strength of 400-530 MPa and a minimum yield strength of 265 MPa. It exhibits good formability, weldability, and impact resistance to withstand the pressures encountered in gas cylinders.

Dimensional Stability: HP265 steel is produced in various thicknesses, widths, and lengths to meet specific requirements for gas cylinder manufacturing.

Surface Quality: HP265 steel should have a smooth and clean surface without significant defects or imperfections that could affect the integrity of the gas cylinders.

HP265 steel is primarily used for welded gas cylinders, such as liquefied petroleum gas (LPG) cylinders, as well as other compressed gas containers. It undergoes strict quality control procedures to ensure it meets the necessary standards and specifications for gas cylinder production.

Please note that it's always advisable to refer to the specific GB/T 6653 standard and consult with the manufacturer for precise information regarding HP265 steel and its properties, as variations may exist depending on the manufacturing process and product forms. Additionally, local regulations and safety guidelines should be followed when handling and using gas cylinders made from HP265 steel to ensure proper performance and safety.
