It has high fatigue strength, abrasion and impact resistance, toughness, and torsional strength.   Fabrication and Heat Treatment: 1. Forging Preheat the steel carefully, then raise the temperature to 1150-1200°C for forging. Do not forge below 850°C. 2. Annealing Heat the AISI 4140 slowly to 800-850°C and allow enough time for the steel to be thoroughly heated. Cool slowly in the furnace to 480°C followed by air cooling. 3. Stress Relieving When parts are heavily machined, ground or otherwise subject to cold work, stress relieving will be beneficial prior to hardening. 4. Hardening AISI 4140 steel is usually supplied ready heat treated to 18-22HRC. If further heat treatment is required annealed AISI 4140 should be heated slowly to 840- 875°C and after adequate soaking at this temperature quench in oil. Temper as soon as the tools reach room temperature. 5. Tempering Heat the AISI 4140 carefully to a suitable temperature selected by reference to a tempering chart or table (usually between 550-700°C, soak at the temperature for 2 hours per 25mm of ruling section, then allow to cool in air. Tempering between 250-375°C is not advised as tempering within this range will seriously reduce the impact value. 6.

Alloy tool steel is a type of steel in which chromium, molybdenum, tungsten, vanadium and other alloying elements are added on the basis of carbon tool steel to improve hardenability, toughness, wear resistance and heat resistance. It is mainly used in the manufacture of measuring tools, cutting tools, impact- resistant tools, cold and hot molds and some special-purpose tools. songshunmoldsteel41404340

CNC Machining Magnesium Alloy Products AZ31 Car Parts 1. Light weight: magnesium alloy is 1/3 lighter than aluminum alloy and 77% lighter than steel, which is the lightest structural metal material in common use. 2. High specific strength and strong rigidity: in the same shape, the rigidity of magnesium alloy products is more than 10 times that of plastics.Under the same rigid conditions, a pound of magnesium is as strong as 1.8 pounds of aluminum and 2.1 pounds of steel.If ABS plastic is replaced with magnesium alloy, the weight of the product can be reduced by 36% and the thickness can be reduced by 64%. 3. Impact resistance: excellent damping shock absorption performance: magnesium alloy resistance to vibration and reduce noise performance is excellent, 10-50 times of aluminum alloy.Magnesium alloy is strong enough to withstand impact, and its thickness is only 1/3 of that of plastic under the same resistance. 4. Good creep resistance. 5. In line with environmental protection: can be completely recycled. 6. Excellent die-casting formability: die-casting can be used to make parts with complex shapes and shell parts with ultra-thin thickness up to 0.45mm thick (ABS plastic 1.2-2mm, aluminum alloy 1.5-2mm).
