This is really where it gets fun. There are generally two categories of alloy steel:low alloy and high alloy. Anything with less than an 8% alloying element is labelled as low alloy, anything over 8% is high alloy. Low alloy steels are by far the most common.
Mar 01, 2019 · As shown in Fig. 1 which is the thermal expansion curve of high-alloy mould steel slab, the black line is the heating curve, and the blue one is cooling curve. These results are the phase transition during cooling. In the CCT curve of high-alloy mould steel, the temperature at which pearlite transforms to austenite (Ac1) and the final temperature at which all the ferrite is converted to Cracking and segregation in high-alloy steel 0.4C1.5Mn2Cr0 Mar 01, 2019 · Unfortunately, there is rare report on the high-temperature ductility of high-alloy steel, which has a high carbon content, such as mould steel. Fig. 4 shows the tensile strength of high-alloy mould steel slab between 9731623 K. It could be concluded that the tensile strength is decreasing along with the temperature increase. D2 Tool Steel - High-Carbon, High-Chromium, Cold-Work Cold-work tool steels include the high-carbon, high-chromium steels or group D steels. These steels are designated as group D steels and consist of D2, D3, D4, D5, and D7 steels. These steels contain 1.5 to 2.35% of carbon and 12% of chromium. Except type D3 steel, all the other group D steels include 1% Mo and are air hardened.

D6 Tool Steel High-Carbon, High-Chromium, Cold-Work D6 Tool Steel High-Carbon, High-Chromium, Cold-Work Steel (UNS T30406) It is standard specification of cold work tool steels for cold work tool, mould, die application, such as hot rolling or hot forging steels or cold drawn steel grade. Cold work AISI D6 tool steel equivalents steel grade D6 is an high alloy Chrome Cold work tool H-13, P-20, 420ss - Alloy Tool Steel Inc.P-20 Pre-Hardened Mold Steel. P-20 is a general purpose mold steel designed for the plastic mold industry. With a combination of Chromium, Manganese, Molybdenum, and Carbon, unwell as being pre-hardened. P-20 is a very popular mold steel grade. P-20 is used for plastic injection and compression molds, and zinc die casting dies.
Feb 13, 2012 · Bulk Density :240 lb./cu. ft. Apparent Density :7.20 gm/cubic centimeter. Approximate Melting Range : 2732 °F Liquidus 2462 °F Solidus Application :In cast iron, chromium increases hardness, strength and resistance to oxidation and growth at high temperatures. High Carbon High Chromium Steel - Tool Steel D2 Round Cold Works D2 tool steel is a high carbon, high chromium tool steel (12% chrome) with extremely high wear resisting properties, heat treatable to 60-62 Rc. D2 steel is very wear resistant but not as tough as lower alloyed steels. D2 tool steel hardens in air with a low order of movement and offers a measure of corrosion resistance when polished. High carbon High chromium Bearing Steel 1. 1 A kind of high carbon and chromium bearing steel which most widely used with a good permance and less alloy content. 2. 2. High hardenability and good comprehensive performance. 3. 3. Good machinability after spheroidizing annealing. 4. 4.
Because of the high chromium content in the high chromium Alloy Steel Ball, easy in the iron surface conjunctive, so it seems that the fluidity of iron is poor, but actually, the fluidity is good. Because the risers of high-chromium castings are difficult to be cut off, so side risers or easy-cut risers should be adopted in the form of risers. STEEL CASTINGS HANDBOOK Supplement 7 Welding of steel) tend to create steep temperature gradients and high thermal stresses in the weld zone. 2.1.1 Iron-chromium alloy types are martensitic or ferritic in microstructure depending on the chromium and carbon content in the composition. They are sub-divided, therefore, into hardenable and non-hardenable groups. Saaj Steel Corporation - High Carbon & High Chromium High carbon and high chromium steel round bar is an air hardening, high-carbon, high-chromium tool steel. It has high wear and abrasion resistant properties. It is heat treatable and will offer a hardness in the range 55-62 HRC, and is machinable in the annealed condition. D2 steel shows little distortion on correct hardening.
Stamping Die manufacturing materials are steel, carbide, steel cemented carbide, zinc-based alloys, low melting point alloys, aluminum bronze, polymer materials and so on. At present, most of the materials used to make Stamping Die are steel-based. The types of commonly used mold working part materials include:carbon tool steel, low alloy tool steel, high carbon high chromium or medium Welding of Steels - Materials DatabaseMedium-carbon steels are readily weldable provided the above precautions are observed. These steels can be welded with all of the processes mentioned above. High-Carbon Steels High-carbon steels include those in the AISI series from C-1050 to C-1095. The composition is similar to medium-carbon steels, except that carbon ranges from 0.30 to 1.00%. High Carbon High Chromium Steel Bars - D2 HCHCR Steel D2 steel is an air hardening, high-carbon, high-chromium tool steel. It has high wear and abrasion resistant properties. It is heat treatable and will offer a hardness in the range 55-62 HRC, and is machinable in the annealed condition. D2 steel shows little distortion on correct hardening.
