EN8
|
0.4% medium carbon steel. A genereal 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.
|
|
EN14
|
A carbon manganese steel.
|
|
EN16
|
A low alloy high tensile steel.
|
|
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.
|
|
EN26
|
A 2.5% nickel chromium molybdenum high tensile steel.
|
|
EN30B
|
4¼% 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.
|
|
EN32
|
Special mild case hardening steel which can provide a hard wearing surface with a tough core.
|
|
EN36
|
Nickel chromium case hardening steel. Give a very hard surface with a strong core and retaining a
high degree of toughness.
|
|
EN40B
|
3% chromium molybdenum nitriding steel. It will achieve a good core strength with a hard
nitrided surface. The nitriding process leaves the component scale free.
|
|
EN41
|
Similar nitriding specification to EN40B but with improved nitriding characteristics. |
|
EN43
|
Unalloyed medium carbon spring steel type specification.
|
|
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. |
