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.
Heat treatment:
Annealing: Temperature: 780-800℃
Holding time: 4-6H; Slow surface cooling
Hardness after annealing: max.250HB
Stress relieving: Temperature: appr.650℃
Holding time: 1-2H; Slow surface cooling
Hardening: Temperature:1020-1050℃
Quenching: oil or polymer(interrupt at appr.120-150℃).
Hardness obtainable: appr.52HRC
Tempering: According to diagram, to values between 800 and 1100 N/mm2.
Nitriding: Possible with appropriate tempering;
However, this treatment reduces resistance to corrosion.
Risunsteel,based on the over one hundred years’s production history of special steel in Huangshi, provide professional services and material for cutting tool companies, mould companies and other industrial enterprises all over the world for years.
