About P20 Steel Grade 1.2738H.H. Plate

Steel World is stockiest, supplier,dealer and manufacturer of the P20 Steel Grade 1.2738H.H. Plate. P20 Steel Grade 1.2738H.H. Plate:

Material Description:
- P20 High Hard (1.2738H.H.) is an improved pre-hardened mold steel specifically designed for large plastic molds.
- It undergoes forging on a 5000-ton press, ensuring maximum deformation during the forging process.
- Supplied hardness ranges from 321 to 352 HB (34-38 HRC), with minimal hardness loss in large cross sections.
Characteristics:
- Homogeneous Strength: Suitable even for large dimensions.
- Applications:
  - Big cavity plates with deep cavities.
  - Highly stressed core components.
Heat Treatment:
- Stress Relieving Temperature: 850F - 900F (Hold 1 hour per inch; air cool).
- Tempering: Heat uniformly and thoroughly at the selected temperature, holding for one hour per inch of total thickness.
Physical Properties:
- Density: Approximately 0.284 lbs/in at room temperature.
- Coefficient of Thermal Expansion:
  - 700F 2000F: 6.8 x 10/F
  - 700F 4000F: 7.0 x 10/F
  - 700F 5750F: 7.1 x 10/F
- Thermal Conductivity:
  - 700F: 202 Btu/in/ft/hr/F
  - 4000F: 209 Btu/in/ft/hr/F
  - 8000F: 216 Btu/in/ft/hr/F
Mechanical Properties (Room Temperature, hardened and tempered to 321 BHN):

FAQ's of P20 Steel Grade 1.2738H.H. Plate:

Q: How is P20 Steel Grade 1.2738H.H. Plate typically used in manufacturing?

A: These plates are frequently utilized in the production of plastic injection molds, die casting tools, and components requiring high toughness and dimensional accuracy, due to their pre-hardened state, high impact resistance, and consistent machinability.

Q: What are the main benefits of choosing P20 1.2738H.H. Plate with enhanced nickel content?

A: Enhanced nickel content improves toughness and extends the plate's lifespan by bolstering strength and resistance to wear. This feature delivers greater reliability in demanding industrial settings.

Q: When should I select high-precision flatness tolerance plates for my project?

A: High-precision flatness tolerance is recommended when your application requires minimal warping or deviations, ensuring optimal structural integrity and dimensional accuracy, especially in tooling and mold-making.

Q: Where can I source P20 1.2738H.H. Plates in India?

A: As a leading supplier, dealer, manufacturer, and exporter, we offer P20 plates with quick dispatch throughout India. Our broad distribution network ensures availability for immediate requirements in all major industrial hubs.

Q: What is the recommended process for machining these plates?

A: Given their pre-hardened and homogeneous microstructure, standard high-speed steel or carbide tools are effective for machining. Proper coolant and moderate speeds should be used to maintain surface finish and tool longevity.

Q: Are these plates easy to form or weld during fabrication?

A: While offering moderate formability and fair weldability, these plates are best suited for forming and welding within standard parameters. Pre- and post-weld treatments are advised to maximize performance when welding is necessary.
