Japanese Material Specs.
(OP)
Could anybody help me or point me to the right direction to find British equivalents for Japanese materials.
I'm trying to order tooling from drawings with the following descriptions : -
S45C
SS400
A20179-T4 (I think this is a carbon alloy alumium)
YH52
STS38
I am struggling to source equivalents!
Also the A20179-T4 has a 30micron coating of "Kashima", now I have never even heard of this. Is this or a coating with similar properties available in the UK?
Thanking you in anticipation,
Paul

RE: Japanese Material Specs.
SS 400 is from JIS G 3101, Rolled Steels for General Structure. Stahlschluessel lists no requirements other than max P & S = 0.050. Equivalent German grade is given as 1.0040, which has the following composition:
C = 0.25 max
Si = trace
Mn = 0.20-0.50
N = 0.007 max
I do not believe A20179-T4 is the proper designation. A201 is an aluminum casting alloy, and 2017 2019 are wrought aluminum alloys. T4 is a temper designation - solution treated and naturally aged. Please confirm the designation. The Kashima note is likely referring to a 30 micron anodic coating. It has been used by Yamaha for reducing friction on front motorcycle forks.
YH52 appears to be aluminum alloy 5052, which is BS EN 573-2 grade EN AW-5052 [AlMg2.5].
STS38 is an old designation for the new grade STS 370 according to JIS G3455, Pipes for High Pressure Service. Composition is C = 0.25 max, Si = 0.10-0.35, Mn = 0.30-0.90, P & S = 0.035 max. BS 3602, 3603, or 3604 may be equivalent standards.

C = 0.56-0.64
Si = 1.80-2.20
Mn = 0.70-1.00
P & S = 0.035 max
Cu = 0.30 max
This grade is similar to SAE 9260 (or 9260H) or 60 Si 7 (EN 89, DIN 17221)
