Hard chrome plating. Hard chrome, also known as industrial chrome or engineered chrome, is used to reduce friction, improve durability through abrasion tolerance and wear resistance in general, minimize galling or seizing of parts, expand chemical inertness to include a broader set of conditions (such as oxidation resistance), and bulking ...
The piston head and extension, as well as the gas port block, barrel bore and chamber, are hard-chrome plated to minimize the effects of propellant fouling. The rifle feeds from 30-round steel magazines that are interchangeable with magazines from the American M16 rifle ( STANAG 4179 compliant). [ 4 ]
41xx steel is a family of SAE steel grades, as specified by the Society of Automotive Engineers (SAE). Alloying elements include chromium and molybdenum, and as a result these materials are often informally referred to as chromoly steel (common variant stylings include chrome-moly, cro-moly, CrMo, CRMO, CR-MOLY, and similar).
New guns are typically available in blued finish options offered as the least-expensive finish, and this finish is also the least effective at providing rust resistance, relative to other finishes such as Parkerizing or hard chrome plating or nitriding processes like Tenifer.
For the testing and calibration of anti-tank guns, the term rolled homogeneous armour equivalency (RHAe) is used when giving an estimate of either the penetrative capability of a projectile or the protective capability of a type of armour which may or may not be steel. Because of variations in armour shape, quality, material, and case-by-case ...
In 1975 an updated version of the gun, the T254E3 was designed, focusing on the use of chrome plating to improve accuracy. It was used to evaluate improvements to the gun's performance using discarding sabot ammunition. Two guns were built and underwent firing trials at Aberdeen [16] and technical evaluations at the Watervliet Arsenal. [17]
Engineers first tried chrome plating on the KM256 tank gun used by K1A1, then coincidentally found a classified method while reworking on defect-plated guns. [ 12 ] The Black Panther is armed with a chrome plated CN08 120 mm 55 caliber smoothbore gun developed by the ADD and WIA (now Hyundai WIA ), and is capable of hitting a 30 centimeters (12 ...
Glock steel parts using the Tenifer treatment are more corrosion resistant than analogous gun parts having other finishes or treatments, including Teflon, bluing, hard chrome plating, or phosphates. [72] During 2010, Glock switched from the salt bath nitriding Tenifer process to a not exactly disclosed gas nitriding process.
