Product Description
Product Description
AISI 4130 Forged Bodies for wellhead equipments
Material Type: Low alloy steel AISI 4130
RAW MATERIAL: Forging, bar stock on mechanical tubing
Service: Ydrogen sulfide (H2S)
MATERIAL PROPERTY DESIGNATION: 75K
ALLOWABLE MELTING PRACTCE:
Material produced to this specification shall be made to fine grain practice using one opf the following melting practice:
- Basic oxygen process (BOP).
- Electric furnace with vacuum degassing of vacuum processing.
- Electric furnace with argon stirred degassing.
- Electric furnace followed by Argon Oxygen Decarburization (AOD).
- Electric furnace followed by either electro slag remelting (ESR) OR VACUUM ARC REMELTING (VAR).
- Vacuum induction melting.
- Electric furnace or induction melting following by a ladle refining process.
HOT WORKING PRACTICES:
Ali wrought materials shall be of pressure vessel quality and shall be formed using a hot working practice which produces a wrought structure. For material produced as a forging, the minimum acceptable total hot work ratio, relative to ingot size, shall be 3: 1.
Mechanical properties requirements:
- Tensile strength, Min. 95, 000 PSI
- Yield strength, Min. 75, 000 PSI
- Elongation in 2", min. 18%
- Reduction in Area, min. 35%
- Surface Hardness 197-235 HB.
