US equivalent to 65Mn (Chinese steel) ?

US equivalent to 65Mn (Chinese steel) ?



I've got hold of some samples of 65Mn stock (.050" thick) that seem
"almost" like stainless.  I'm told in China it's considered a
cheap,tough steel good for a lot of applications requiring some

By this page it seems that 1065
is the closest equivalent, but this stuff doesn't look like any 1065
samples I've seen.  Does anyone have any experience with 65Mn, and
could they cite better references for it's equivalent ?


RE: US equivalent to 65Mn (Chinese steel) ?

I did not find alot of good documentation, mostly chinese sites, but I found these:


            C           Si          Mn         Cr         Ni         S          P
65Mn      0,62-0,70   0,17-0,37   0,90-1,20   0,025max   0,025max   0,035max   0,035max
China  GB1222-84
Russia  GOST 14959-79
Japan  JIS G 4801-84
USA  ASTM A29-93
British  BS 1429-80
Germany  DIN 17222-79
France  NF A35-057-79
ISO  8458-3-92

It's a spring steel with thermal resistance.  Also used as the base of diamond coated saw blades.

RE: US equivalent to 65Mn (Chinese steel) ?


65Mn is equivalent to grade 1065 according to SAE J403.  As Pressed mentioned, it is often cold-rolled and heat treated to high strength (called spring temper).  ASTM A 29 is a standard for bar steel, so it is not appropriate for cold rolled strip.  Grade 1065 is one of the grades covered by ASTM A 682 Standard Specification for Steel, Strip, High-Carbon, Cold-Rolled, Spring Quality, General Requirements for.
