3,Chemical composition
C=1.45~1.70, Si≤0.40, Mn≤0.40, Cr=11.00~12.50, Mo=0.40~0.60, V=0.15~0.30
4,Delivery Condition
EAF or ESR, Cold work and Forged, black, peeled or turned surface, annealed,
hardness: HBS=207~255
5,Performance
High carbon & high chrome ledeburite steels with good hardenability and high abrasion resistance.
Their carbon contents are much lower than that of Crl2 steels. And meanwhile our steels are added
with molybdenum and vanadium, so steel hotworking character, impact toughness and carbide
distribution have been significantly improved.
6,Applications
It can be used to make different kinds of moulds that has big cross section,complex shape,also the
moulds can bear large shock with high abrasion resistance and high resistance.

Principal Design Features
One of the most widely used precipitation hardening grades in the business. While soft and ductile in the solution annealed condition, it is capable of high properties with a single precipitation or aging treatment. Characterized by good corrosion resistance, high harness, toughness and strength.
Machinability
Long, gummy chips characterize this alloys machinability. It can be machined in the annealed condition, however condition H1150M will yield best results. Post machining solution treatment of parts will be required prior to final hardening if machining in this condition.
Heat Treatment
CONDITION A--Soak at 1900 F (1038 C) for 30 minutes and cool below 60 F (16 C) for complete martensite transformation. CONDITION H 950- Treat Condition A material at 900 F(482 C) for 1 hour, air cool.. CONDITION H925, H1025, H1075, H1100, H1150- Soak solution treated material for 4 hours at specified temperature, air cool, CONDITION H1150M- Soak solution treated material at 1400 F (760 C) for 2 hours, air cool, then re-heat to 1150 F (620 C) for 4 hours and air cool.
Welding
Successfully welded by common fusion and resistance methods, this alloy should not be joined by oxyacetylene welding. AWS E/ER630 filler metal is recommended if required.
Forging
Soak for 1 hour at 2150 F (1177 C) prior to forging. Do not work below 1850 F (1010 C). Post-work solution treatment is required prior to final hardening.
