Detailed Product Description: | Good translation Metal Products (Shanghai) tool steel companies (domestic alloy tool steel / imported alloy tool steel) 9SiCr alloy tool steel / 9SiCr steel / 9SiCr steel bar / 9SiCr Coil / 9SiCr steel / 9SiCr pipe / 9SiCr wire (good translation Metal Products (Shanghai) Co., Ltd.) Material Name: Alloy tool steel Grade: 9SiCr Standard: GB / T 1299-2000 Delivery status: hot and cold rolling. Annealed state general delivery. Delivery specifications: hot 2.5 ~ 6.0mm (plate), cold-rolled 1.5 ~ 2.5mm (with) Features and application: High-carbon alloy tool steel, toughness, has good temper resistance, heat treatment deformation. The uniform distribution of carbide steel, carbide precipitation network is not easy, and easy to remove normalizing, normalizing can be eliminated through the mesh and the coarse carbide film organization. But the lack of compressive strength and wear resistance, processability is poor. The steel surface residual carbon content of 0.6% -0.7% of the decarburized layer, due to the resulting decrease in the surface carbide layer increases the sensitivity of overheating. The normal heating surface hardness after quenching can still reach 60-62HRC, but the bending strength was decreased by 40% -50%. Surface layer of grain size to 7, the center is 10. The steel forging good performance, as easy to decarburization, or the need to protect the atmosphere in the neutral atmosphere in the heating furnace. Subjected to hot forging quenching, tempering can be fine sorbite organization, simplify processes, save time and energy saving, both good cutting performance, but also the ideal heat treatment organization. Softening temperature of the steel heat 320 ℃, hardenability better than the chrome steel, oil quench hardened depth of 40-50mm. Zero thermal quenching of the steel annealing process, can eliminate the twist wire = plate heated by conventional quenching caused by oxidation and decarbonization of early failure, repair or non-uniform austenite martensite can be refined, after the fire has been hidden twist martensite or fine needle-like martensite, good strength and toughness of this organization. 9SiCr measuring and cutting of steel, is commonly used low alloy tool steel with high hardenability and hardenability, and higher temper resistance. Two more to use an example: 1 The steel used for punching ≥ 3mm material thickness in the complex shape of the punching die punch die inserts, punches, suggested doing hardness 58-62HRC, the die is recommended to do 60-64HRC. 2 batch of soft materials such as plate steel stamping die used 9SiCr. 3 is good for rolling mode, the ultrafine pretreatment, double the service life expectancy, 4 of the M50 × 2 thread rolling steel plate using hot forging pre-quenched and quenched martensite sorbite closer to the organization, coupled with "shell quenching", life expectancy increased by 2-3 times. 5 loads of light or small batch production mode with a cold heading 6 The steel used for more sophisticated molds. 7 The steel used for blanking die, punch, embossing mold. 8 for high-strength cold-working die steel. 9 for aluminum cold extrusion die, do punch, suggested that hardness 60-62HRC. 10 gear die, scissors and cold Kun. 11 is a variety of fine lamination punching tools, cold heading die of basic materials. 12 does not apply to severe with high wear resistance, cutting and deformation tools, such as the tap drill reamers die cutter gear pull knives. Application: 9SiCr alloy tool steel can be used to create complex shapes, small deformation, high abrasion resistance, low-speed cutting tools such as drill bits, thread tools, reamers, die, tap, thread rolling board and rolling wheels. (Plastic mold steel, top of the rod can be used to create large size, complex shape and high precision plastic film. Chemical composition ● Chemical Composition: Carbon C: 0.85 ~ 0.95 Si Si: 1.20 ~ 1.60 Manganese Mn: 0.30 ~ 0.60 Sulfur S: ≤ 0.030 Phosphorus P: ≤ 0.030 Chromium Cr: 0.95 ~ 1.25 Ni: to allow the residual content of ≤ 0.25 Copper Cu: to allow the residual content of ≤ 0.30 Mechanical properties ● Mechanical Properties: Hardness: Annealed, 241 ~ 197HB, indentation diameter of 3.9 ~ 4.3mm; 187 ~ 229HB (manufacturing thread tools); quenching, ≥ 62HRC Heat treatment process ● Heat treatment and microstructure specifications: Heat treatment specifications: sample quenching 820 ~ 860 ℃, oil cooling. ● Delivery status: the status of delivery of steel to annealing. ● physical performance / thermal processing / pre-heat treatment / hardening / tempering The company offers domestic and imported alloy tool steel varieties, complete specifications, special specifications can be customized processing.
