Special melting and forging practices result in ultra-high microcleanliness and a W-1 WATER HARDENING TOOL STEEL Preheating. 1200-1250° F. Preheat time in furnace is ¾ Hr. per inch of thickness. Hardening. 1375-1450° F. In water or in a brine solution. Small tools or parts may be heated in molten lead or in a salt bath. Soak time is 10 minutes per inch of thickness. Minimum of30 minutes.
A-2 AIR HARDENING TOOL STEEL A-2 is an air hardening chromium-molybdenum-vanadium alloy die steel. This grade offers intermediate abrasion resistance generally between O-1 and D-2. A-2 is characterized by: - Good wear resistance - Good machinability - High compressive strength - Very good non-deforming properties - Deep hardening - High dimensional stability after hardening and tempering 1018 COLD ROLL LOW CARBON STEEL 1018 is a medium-low carbon steel that is one the most commonly available of the cold-rolled steel alloys. Chemically, it is very similar to A36 Hot Roll steel, but the cold rolling process creates a better surface finish and better welding and machinability. It is an excellent choice for fixtures, jigs, shafting and other machine parts. S-1 SHOCK RESISTING TOOL STEEL S-1 is a medium-carbon steel which combines moderate hardness with good impact toughness. It is a deep-hardening, oil-hardening steel designed for shock and impact loading applications. S-1 is a medium-carbon steel which combines moderate hardness with good impacttoughness.
A-6 AIR HARDENING TOOL STEEL A-6 tool steel air-hardens at a relatively low temperature (approximately the same temperature as oil-hardening grades) and is dimensionally stable. Therefore it is commonly used for dies, forming tools, and gauges that do not require extreme wear resistance but do need high stability.

D-2 AIR HARDENING TOOL STEEL D-2 tool steel is a versatile high-carbon, high-chromium, air-hardening tool steel that is characterized by a relatively high attainable hardness and numerous, large, chromium rich alloy carbides in the microstructure. These carbides provide good resistance to wear from sliding contact with other metals and abrasive materials. Although other steels with improved toughness or improved wear M-42 HIGH SPEED TOOL STEEL M-42 is a molybdenum-chromium-vanadium-tungsten high speed steel alloy with an additional 8% cobalt. It is widely used in metal manufacturing because of its superior red-hardness as compared to more conventional high speed steels, allowing for shorter cycle times in production environments due to higher cutting speeds or from the increase in time between tool changes. M-42 is also less prone GUIDELINES FOR WELDING TOOL STEEL Preheat the part to as high a temperature as is consistent with the final hardness requirements, preferably in the range of 400-1000F (250-538C). The preheat temperature for hardened tools should not exceed the original draw temperature. Furnace preheating is desirable but torch preheat is widely practiced. Welding may then be performedusing
H-11 HOT WORK TOOL STEEL H-11 hot work tool steel is a 5% chromium hot work steel that is characterized by excellent impact toughness. It contains less vanadium than the widely-used H13 hot work tool steel. This provides for the higher toughness, with some reduction in wear resistance and temper resistance. H-11 hot work tool steel is a deep-hardening, air-hardening steel that exhibits minimal size change during heat S-7 SHOCK RESISTING TOOL STEEL S-7 Shock Resisting Tool Steel. S-7 is an air or oil hardening tool steel that is characterized by very high impact toughness. The combination of strength and high toughness makes S-7 tool steel a candidate for a wide variety of tooling applications. S-7 tool steelcan be
T-1 HIGH SPEED TOOL STEEL Preheating. 1500-1550° F. Preheat time in furnace is ¾ Hr. per inch of thickness. Heating up to temperature as slow as possible. Hardening. 2325-2375° F (furnace) 2275-2350° F (salt bath) Quench in air or warm oil. To minimize quenching strains, quench in salt at 1000° F. For maximum wear resistance, harden at 2375° F. A-8 AIR HARDENING TOOL STEEL A-8 is an air-hardening tool and die steel. It exhibits good wearing qualities with excellent toughness characteristics. It is well suited for many metals working dies and punches, which operate in the hardness of Rockwell C 55-60. A-8 is an air-hardening tool and die steel. It exhibits good wearing qualities with excellent toughness S-1 SHOCK RESISTING TOOL STEEL S-1 is a medium-carbon steel which combines moderate hardness with good impact toughness. It is a deep-hardening, oil-hardening steel designed for shock and impact loading applications. S-1 is a medium-carbon steel which combines moderate hardness with good impacttoughness.
D-7 AIR HARDENING TOOL STEEL 1400-1500° F. Preheat time in furnace is ¾ Hr. per inch of thickness. Heating up to temperature as slow as possible. Hardening. 1900-2000° F. In air. Allow to cool to 125-150° F before tempering. Soak time is 15 minutes per inch of thickness. Minimum of 30 minutes.Skip to content
