ALL About Scissors - Precision Sharpening Inc.

Now you have a pretty good hardness and flexibility on your tool except that the chromium in the steel will not permit a long lasting cutting edge. To make the cutting edge last longer, the steel is subjected to about 120 degrees below zero; in other words, "Ice Tempered". The tool is not much harder, but the steel structure is at its optimum.

CS95 Carbon Spring Steel - BSS Spring Steel Strip

CS95 is a spring steel with a carbon content of between 0.90% and 1.00%, and is generally used where higher hardnesses and wear resistance is required, or where a higher strength is required in a lower thickness material. CS95 is usually supplied in the hardened and tempered condition, and it is commonly supplied with a polished finish. DESIGN GUIDELINES FOR THE SELECTION AND USE OF Reference is often made to stainless steel in the singular sense as if it were one material. Actually there are over 50 stainless steel alloys. Three general classifications are used to identify stainless steels. They are:1. Metallurgical Structure. 2. The AISI numbering system:namely 200, 300, and 400 Series numbers. 3.

Die Steel - Die Steel EN31 Manufacturer from Chennai

Die Steel EN31. EN31 is a high carbon Alloy steel which achieves a high degree of hardness with compressive strength and abrasion resistance. Forge at 1000°/1050°C. Heat slowly, allowing sufficient time at the forging temperature for the steel to be thoroughly soaked through. Grade 65Mn Steel High Carbon Spring Steel Properties GB 65Mn Steel. 65Mn steel is a Chinese GB standard spring steel grade, Manganese (Mn) improves hardenability, so the strength, hardness, elasticity and hardenability are higher than that of 65# steel, but it has overheat sensitivity and temper brittleness. Water quenching tends to form cracks. The annealed state has good machinability, low cold deformation plasticity, and poor weldability. Precision Stainless Steel Strip factory, Buy good quality Thin strip , precision stainless steel strip in light gauge grade 304 1.4301 Stainless Steel Grade 304 is the standard 18/8 (18% chrome, 8% nickel) austenitic stainless steel.

Quenching and tempering of steel - tec-science

  • IntroductionProcess StepsStress-Strain DiagramInfluence of Alloying Elements on Martensite FormationInfluence of The Alloying Elements on The Choice of Quenching MediumThe heat treatments explained in the chapter on annealing processesmainly related to the improvement of production-orientated properties such as formability, machinability, etc. In many cases, however, a high degree of hardness or strength is required. This can be seen, for example, in a file blade for processing workpieces. To ensure that the file removes the material from the workpiece and does not become blunt itself, it must be correspondingly wear-resistant and therefore very hard. Another example where high 420 Stainless Steel McMaster-CarrSuitable for making molds, 420 stainless steel is a hard, wear-resistant material that can be finely polished to a very smooth surface. Linear Motion Shafts Combine these general purpose shafts with a linear bearing and shaft support to create a basic linear motion system. Spring Steel Sheets And Plates - C60 Steel Plate The springs use for counter balancing rolling shutter can be make from spring steel wire or flat spring steel strip. Flat spring steel strips are widely used in rolling shutter industies, due to its durability and 3000 cycles rolling up and down per year. It is usually cut into 3m, 3.5m, 5m, 5.5m, 6m Steel McMaster-CarrEasy-to-Weld A572 AlloySteel Sheets and Bars. Combining strength with weldability and formability, A572 alloy steel is an economical choice for structural components, such as channels, beams, and framing. It has a low carbon content, making it easy to weld with a variety of welding methods.
