HP295 steel plate for welded gas cylinders is specifically engineered for LPG cylinders, propane tanks, and pressure vessels under the GB6653 standard.
HP295 steel plate
For manufacturers aiming to improve production efficiency, safety performance, and cost control, HP295 offers a more advanced solution compared with HP265.
While both grades are widely used in gas cylinder production, HP295 provides higher strength with stable ductility, making it more suitable for modern automated manufacturing and export-grade cylinder requirements.
Mechanical Properties of HP295 vs HP265 Steel Plate
The core difference between HP295 and HP265 lies in their strength levels and performance balance.
| Property | HP265 Steel | HP295 Steel |
|---|---|---|
| Yield Strength | ≥265 MPa | ≥295 MPa |
| Tensile Strength | 410–480 MPa | 440–560 MPa |
| Elongation | ≥28% | ≥26% |
Strength Advantage of HP295 Steel Plate
HP295 delivers a clear advantage in strength:
- +30 MPa higher yield strength than HP265
- Better resistance to internal pressure
- Supports thinner wall design
This enables manufacturers to:
- Reduce material usage
- Lower cylinder weight
- Improve transportation efficiency
Formability of HP295 vs HP265 Steel Plate
Both steels are suitable for cold forming, but their performance differs in real production:
HP265:
Easier forming due to higher elongation
Suitable for lower-end or simple applications
HP295:
Balanced strength and ductility
More stable in high-speed stamping and deep drawing
HP295 provides more consistent forming quality in mass production.
Welding Performance of HP295 vs HP265 Steel Plate
Welding quality directly affects cylinder safety.
- HP265:
Good general weldability
- HP295:
Lower impurity content
Reduced crack sensitivity
More stable weld seams
HP295 is better suited for automated welding lines and large-scale production.
Application Difference of HP295 vs HP265 Steel Plate
| Grade | Main Applications |
|---|---|
| HP265 | Standard LPG cylinders, small gas containers |
| HP295 | LPG cylinders, propane tanks, higher-pressure cylinders |

What are the advantages of HP295 steel compared to HP265?
Compared with HP265, HP295 steel provides higher yield strength and better pressure resistance, which increases the safety margin of gas cylinders. Although it may have slightly higher forming resistance, it remains suitable for standard manufacturing processes with proper control.
What is the chemical composition of HP295 steel?
The chemical composition of HP295 steel is strictly controlled, with carbon content not exceeding 0.20%, silicon ≤0.35%, manganese ≤1.20%, phosphorus ≤0.025%, and sulfur ≤0.015%. This balanced composition helps achieve a good combination of strength, weldability, and toughness.
Is HP295 steel suitable for welding?
Yes, HP295 steel has good weldability due to its relatively low carbon content and controlled impurity levels. It can be used with common welding methods such as manual arc welding, submerged arc welding, and gas shielded welding, while maintaining stable weld quality and reducing the risk of cracks.
What applications is HP295 steel used for?
HP295 steel is mainly used for manufacturing liquefied petroleum gas cylinders, industrial gas cylinders such as oxygen and nitrogen containers, as well as other medium to high-pressure gas storage vessels. Its higher strength makes it particularly suitable for applications with stricter safety requirements.
What thickness and size ranges are available for HP295 steel?
HP295 steel is typically available in thicknesses ranging from 1.5 mm to 20 mm, with widths from 1000 mm to 2500 mm, and lengths that can be customized according to production needs. For gas cylinder manufacturing, thinner specifications are more commonly used.
