Contact us for those hard to find carbon and alloy steel specifications.
EN8
0.4% medium carbon steel. A general purpose steel for applications requiring added strength and superior tensile properties to mild steel specifications.
EN9
0.5% carbon steel giving higher tensile than EN8. Can be induction or flame hardened.
EN19
1% chromium molybdenum high tensile steel. Suitable for highly stressed applications where greater strength is required.
EN24
Nickel chromium molybdenum high tensile steel. Has good wear and shock resistance and is suitable for tensile ranges up to 1550 N/mm2.
EN30B
41/4% nickel steel. Achieves a good through hardness with air or oil hardening. It is capable of taking a good polish and is widely used as a plastic mould steel.
EN31
High carbon alloy steel which achieves a high degree of hardness with compressive strength and abrasion resistance.
EN36
Nickel chromium case hardening steel. Give a very hard surface with a strong core and retaining ahigh degree of toughness.
EN45
Silicon mangenese alloy spring steel.
EN47
Tough oil quenching spring steel which, when heat treated, offers good wear resistance.
SAE 8620
A low alloy case hardening steel.
AISI 4140
Chromium molybdenum high tensile steel. Supplied 18-22HRc (Hardness Rockwell)
AISI 4145
Chromium molybdenum high tensile steel similar to 4140. Supplied 30-36HRc
AISI 4130
Chromium molybdenum steel supplied 18-22HRc. Lower carbon content that AISI 4140.
AISI 6150
A chromium vanadium spring steel type steel.
