P420M | Pressure Vessel Steel
P420M | Pressure Vessel Steel
P420M is a thermomechanically rolled fine-grain steel for pressure vessels. “P” means pressure use, “420” indicates minimum yield strength in MPa, and “M” refers to thermomechanical rolling. It offers excellent weldability and high strength at elevated temperatures. It’s commonly used in energy, petrochemical, and boiler industries. The European steel number is 1.8826.
Description
What is P420M？
P420M contains about 0.16% carbon and 1.7% manganese, with smaller amounts of silicon and other alloying elements. It is a solid, fine-grain steel, usually in plate form. P420M is thermomechanically rolled, offering excellent weldability and strength at high temperatures. It is mainly used in pressure vessels, boilers, and industrial structures in the energy and petrochemical sectors. The steel is hot-rolled for improved properties, with subgrades like P420ML1 and P420ML2 for low-temperature conditions.Why Choose P420M Pressure Vessel Steel?
Are you looking for high-strength steel for pressure vessels and high-temperature applications? We recommend P420M for its great weldability, strength, and reliable performance under heat and pressure. It’s a tough, easy-to-use material that meets industry standards. P420M stands out for its toughness and versatility in high-stress environments. Subgrades like P420ML1 and P420ML2 are perfect for low-temperature applications. For more demanding needs, alternatives like A516 or 13CrMo4-5 offer extra strength and temperature resistance. By choosing P420M, you ensure safety, durability, and reliable supply from a trusted partner.Product Specification

- Seaworthy Packaging: We use strong, durable materials such as wooden pallets or crates to ensure the steel plates are securely packed for long sea voyages, preventing damage from movement.
- Waterproof Wrapping: P420M is covered with high-quality waterproof materials to protect it from moisture and corrosion during transport, especially in humid environments.
- Edge and Surface Protection: We apply edge protectors and use padded coverings to safeguard the steel from scratches and dents, ensuring that the material’s surface and edges remain intact.
- Custom Labeling and Marking: All shipments are clearly labeled with handling instructions and customer-specific requirements, facilitating smooth customs clearance and proper storage upon arrival.
This careful attention to packing guarantees that P420M steel from SteelPRO Group arrives safely and ready for immediate use.
Machining
P420M Heat Treatment
P420M Surface Finish
- Shot Blasting: Removes surface impurities, rust, and scale, ensuring a clean surface for further processing.
- Pickling and Passivation: Enhances corrosion resistance by cleaning the steel surface and forming a protective oxide layer.
- Anti-Corrosion Coating: Applies a protective layer that shields the steel from moisture and environmental corrosion, ideal for marine and industrial environments.
- Galvanization: Adds a zinc coating to protect P420M steel from corrosion, particularly in harsh or exposed environments.
- Phosphating: Improves paint adhesion and provides mild corrosion protection by creating a phosphate coating on the surface.
Custom surface treatment requirements can be accommodated upon request.
