Here are Grade 100 Carbon Ball Descriçãos:

AISI420 Stainless Steel Ball is a martensitic stainless steel ball with 12 percent Chromium which is sufficient to give good corrosive resistance properties tainless steel cleaning ball.It's best corrosive resistance is when hardened and surface is ground or polished. It has good ductility in the annealed condition but can be hardened up to 500HB (highest of the chromium grades) due to its excellent harden-ability, 440c stainless steel ball for pen.steel ball for cartridges.It is capable of getting hardened up to 50 HRC Rockwell or higher. 420c 440c stainless steel ball g10 g1000.Martensitic Grades are known for high hardness and allowances must be made for poor weld ability and usually allowances for a final harden and temper treatment. 420 steel is magnetic and welding is not recommended. Material will not pass the 72 hours salt bath test.

Carbon steel mainly includes low carbon steel (AISI1010/1015), medium carbon steel (AISI1045) and high carbon steel (AISI1085). In the precision steel ball industry, low carbon steel balls and high carbon steel balls are commonly used. Low-carbon steel balls are also called soft steel balls, which have low strength, low hardness and softness, and are suitable for processing such as drilling and tapping; high-carbon steel balls, also known as hard steel balls, have higher strength and hardness, high elastic limit and fatigue limit (especially notch fatigue limit), suitable for applications with high hardness requirements and low wear.
