For example, a 1060 steel is a plain-carbon steel containing 0.60 wt% C.[4] An "H" suffix can be added to any designation to denote hardenability is a major requirement. The chemical requirements are loosened but hardness values defined for various distances on a Jominy test.[2] Major classifications of steel[1] SAE designation Type 1xxx Carbon ...
Rolling ball tack is measured when a stainless steel ball is released onto a strip of tape at a 30° angle. The distance the ball travels is measured, generally in inches or centimeters. Loop tack is where a piece of tape is looped, adhesive side out, and quickly dipped onto a substrate and removed. This is generally measured in oz/in. Page 11

The material to be used to produce the part must be identified in the order. Material for steel castings is generally ordered to ASTM requirements, although other specifications may be used. This supplement contains a summary of the scope, chemical composition requirements and mechanical property requirements of these material or
Thus, "2340" indicates a nickel steel of approximately 3% nickel (3.25 to 3.75) and 0.40% carbon (0.38 to 0.43). The basic numerals for the various types of AISI steels (including plain-carbon steels) are listed in the table below.
steel - steel - Testing of properties: The testing of steel's properties often begins with checking hardness. This is measured by pressing a diamond pyramid or a hard steel ball into the steel at a specific load. The Vickers Diamond Pyramid Hardness tester, which measures the DPH mentioned above, uses an indenter with an included angle of 136° between opposite faces of …

The typical test uses a 10 mm (0.39 in) diameter hardened steel ball as an indenter with a 3,000 kgf (29.42 kN; 6,614 lbf) force. The load is maintained constant for a specified time (between 10 and 30 s). For softer materials, a smaller force is used; for harder materials, a tungsten carbide ball is substituted for the steel ball.
The most common material used to produce the load carrying components in precision ball bearings, roller bearings, and tapered roller bearings is 52100 chrome steel. These components are the bearings inner and outer rings, balls and rollers. The chemical composition of this steel has high carbon and about 1.5% chromium content.
This option is similar to 420 steel but has an increased amount of chromium. This allows the ball bearing to have even more corrosion resistance and toughness. Composition & Properties. When deciding which metal ball bearing is best for your application, it is important to look at the chemical makeup.
