AISI  8620 Steel  is a low alloy nickel, chromium, molybdenum case hardening steel, generally supplied in the as-rolled condition with a maximum hardness of HB 255max. SAE steel 8620 offers high external strength and good internal strength, making it highly wear resistant. AISI 8620 steel has a higher core strength than grades 8615 and 8617. SAE 8620 alloy steel is flexible during hardening treatments, thus enabling improvement of case/core properties. Pre-hardened and tempered (un carburized) 8620 can be further surface hardened by nitriding but will not respond satisfactorily to flame or induction hardening due to its low carbon content. Steel 8620 is suited for applications which require a combination of toughness and wear resistance. This grade is commonly supplied in round bar. 1. AISI 8620 Steel Supply Range 8620 Round Bar: diameter 8mm – 3000mm 8620 Steel Plate: thickness 10mm – 1500mm x width 200mm – 3000mm 8620 Square Bar: 20mm – 500mm 8620 tubes are also availabl

M2 Tool Steel | 1.3343 | HS-6-5-2C| SKH51 AISI  M2 Tool Steel  is molybdenum based high-speed steel in tungsten–molybdenum series.  HSS  grade steel  M2  is a medium alloyed high speed steel which has good machinability. The H-SS M2 chemical composition gives a good combination of well-balanced toughness, wear resistance and red hardness properties. Widely used for cutting tools such as twist drills, taps, milling cutters, saws, knives etc. Also commonly used in cold work punches and dies and cutting applications involving high speed and light cuts. Grade M2 High Speed Steel is by far the most popular high speed steel replacing high speed steel grade  T1  in most applications because of its superior properties and relative economy. We are one of leading AISI M2 HSS steel supplier and we can offer better quality and M2 alloy steel price for your various applications. 1. Supply Range of M2  tool steel  High Speed M2 Steel Round Bar:  diameter 2mm – 200mm HSS M2 Steel Flat

Everything You Need To Know About Injection Molding

What is Injection Molding: Injection Molding is a manufacturing process for producing parts in large volume. It is most typically used in mass-production processes where the same part is being created thousands or even millions of times in succession. Why Use Injection Molding: The principal advantage of injection molding is the ability to scale production en masse. Once the initial costs have been paid the price per unit during injection molded manufacturing is extremely low. The price also tends to drop drastically as more parts are produced. Other advantages include the following: Injection Molding produces low scrap rates relative to traditional manufacturing processes like CNC machining which cut away substantial percentages of an original plastic block or sheet. This however can be a negative relative to additive manufacturing processes like 3D printing that have even lower scrap rates. Note: waste plastic from injection molding manufacturing typically comes consistent
