About P20 Steel Grade 1.2738H.H. Flat

Steel World is stockiest, supplier,dealer and manufacturer of the P20 Steel Grade 1.2738H.H. Flat. 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):
- Yield Strength: 130 KSI
- Tensile Strength: 150 KSI
- Elongation: 15%
- Reduction Area: 35%
Welding:
- Preheat insert to 900F 1000F and maintain temperature above 800F during welding.
- Use TIG with D.C. positive polarity.
- Slowly cool down to 350F before post-heat treatment.
Polishing:
- Can achieve an A-2 surface finish with proper procedures.
- Caution to avoid over-polishing (orange peel effect and pitting).
