ASTM 3Cr17Mo - - - - - - - -

GB - - - - - - - - - Trade of steel and characteristics:

Hardenable steel, resistant to oxidation and corrosion.

The high chromium content combined with low carbon provides a good resistance to corrosion, subject to surface being perfectly polished after heat treatment.

Applications:

Moulds for corrosive thermoplastic material.

Chromizing is not necessary.

These two grades allow very high polish.

They are generally supplied pretreated to 800-1100 N/mm2 according to request.

Heat treatment(if necessary):

steel suppliers: Hubei Risunsteel Co., Ltd.
