Carbon & Low Alloy

Low Alloy steel grades 4130, 4140, 4145 and 1/4 Cr - 1Mo F22 type.
These are strengthened by the addition of chromium and molybdenum in varying amounts. This provides increased toughness and hardening capability.
These materials are susceptible to sulphide stress corrosion cracking in sour gas environments and their hardness is therefore linked to 22HRC by NACE MRO1175/ISO15156.
Common applications include valve bodies and casing hangars.
These products are available either Normalised or Hardened & Tempered to:
4130 60 KSI min 22 HRC max
4140 80 KSI min 22 HRC max
4145 110 KSI min 30 - 36 HRC max
