Boiler and Pressure Vessel Steel
Welding gas bottle steel is dedicated used to manufacturing steel welded gas bottles for repeatedly holding liquefied petroleum gas under normal atmospherical temperature (-40～60℃) with a test pressure of 3. 2MPa.
Steel welded gas bottle is the category II and III pressure vessel strictly controlled by the National Boiler and Pressure Vessel Safety Supervisory Bureau, which is directly related to customer safety, and the certification (production license) shall be revised every 5 years.
The steel for boiler and pressure vessels is mainly divided into three categories: the first category is medium and normal pressure vessel steel such as Q245R、Q345R、15CrMoR, which are mainly applied in civil boilers and ordinary industry boilers; the second category is low temperature pressure vessel steel such as 16MnDR、15MnNiDR, which are mainly used in locomotive and chemical machinery industry; the third category is hardening and tempering high strength steel such as 12MnNiVR, which is mainly applied in special industries such as boiler of the power station and nuclear power station.

Why Boiler & Pressure Vessel Steel Requires Higher Performance?
High Strength and Resistance to Pressure
Boiler steel must handle internal steam pressure ranging from 1 MPa to 20 MPa or higher. It must maintain high yield and tensile strength without deformation or rupture.
High-Temperature Stability
In elevated temperature environments (400–600°C), boiler steel must maintain a stable microstructure and mechanical properties without softening.
Excellent Toughness at Low Temperature
Impact resistance at low temperature (−20°C, −40°C, −60°C) ensures safety even under sudden cooling.
Weldability and Fabrication Performance
Pressure vessels involve complex welding processes; poor weldability increases the risk of cracks.
Therefore, boiler steel must exhibit:
- low sulfur and phosphorus
- controlled carbon content
- good HAZ (heat affected zone) toughness
Corrosion Resistance and Hydrogen Embrittlement Resistance
Internal media may contain acids, steam, ammonia, or hydrogen sulfide.
Proper alloying (Mo, Cr, Ni, Mn) ensures long-term corrosion resistance.
Huaxiao Metal can provide N or QT heat-treatment boiler steel to enhance safety and lifespan.

FAQ: Boiler & Pressure Vessel Steel
What is the difference between boiler steel and structural steel?
Boiler steel has higher toughness, better weldability, stricter chemical composition, and can withstand pressure and temperature cycles. Structural steel is not suitable for pressure applications.
Can boiler steel be used at low temperatures?
Yes. Certain grades such as A516 and low-alloy series maintain good toughness even at -40°C or -60°C.
Can boiler steel be used for high-temperature service?
Yes—A387, 16Mo3, and Cr-Mo steel are designed for high temperature.
What documents are provided with the shipment?
MTC 3.1 / 3.2, heat number traceability, chemical composition report, and mechanical property report.
How do I choose the right grade for my vessel?
Selection depends on pressure, operating temperature, medium corrosion, and vessel design code. Our engineers can provide recommendations.
