Typical composition[edit]

A typical composition is:

Carbon (C) 1.0%, Phosphorous (P) 0.04%, Manganese (Mn) 0.3%, Sulphur (S) 0.04%, Silicon(wtf) (Si)= SILICIUM (no Silicon) 0.25%

Where's the Iron???

I would assume the rest is iron. —BenFrantzDale 05:09, 30 November 2005 (UTC)

Iron it's a rest of 100% - think, please.


I added (Maximum) after Sulfur, as sulfur is an impurity, not an alloying compound. —Preceding unsigned comment added by (talk) 13:45, 4 January 2008 (UTC)

OHNS & HCHCR[edit]


What do grades like OHNS (oil hardening non-shrinking steel), HCHCR (high C high Cr) that are frequently used in India mean? What are their compositions? Their equivalent grades? —Preceding unsigned comment added by Smtwkla (talkcontribs) 00:05, 19 September 2008 (UTC) there is no such steel -and the alloys said as locally is 'D' series -toxn — Preceding unsigned comment added by (talk) 09:29, 17 December 2015 (UTC)

Image request[edit]

What do you want an image of? Tool steel looks like carbon steel. Please elaborate. Wizard191 (talk) 14:08, 11 November 2009 (UTC)
