High hardness armor steel (HHA) is developed for construction of military vehicle. HHA steel is complicated to weld as a result of its higher carbon content. Temporary researches give us
Armor Plate High Hardness Armor Plate Alro Steel MIL A popular high hardness armor grade (HHA), 46100 is selected for use by alldepartments and agencies of the Department of Defense. This grade is produced in plates up to 2 inches (51mm) thick with hardness requirements of 477-534 BHN and CharpyImpact testing on every plate. For more information call Alro Steel at 888-888-2576
High-speed steel is a complex alloy steel containing carbide-forming elements such as tungsten, molybdenum, chromium, vanadium, and cobalt. The total amount of alloying elements is about 10-25%. It can still maintain high hardness under the condition of high heat generated by high-speed cutting (about 500 ), and HRC can be above 60.
Difference Between Low, Medium & High Carbon SteelDec 14, 2019 · High carbon steel has high strength and hardness (Rockwell C can be up to 60-65 HRC), high elastic limit and fatigue limit after proper heat treatment or cold drawing hardening, and the cutting performance is acceptable, compared to low carbon steel and medium carbon steel, its weldability and cold plastic deformation is the worst.
High Hardness Steel P20-HRC 40-Plastic Mould Steel-1.2738High Hardness Steel P20 HRC 40 is the Versatile, Low-Alloy Steel. It has Good Toughness at Common Strength Levels. To put it another way, Steel P20 HRC 40 Contains a Variety of Carbon and its Alloy. This high hardness steel p20 is best for making of tools.
High-strength low-alloy (HSLA) steels, or microalloyed steels, are designed to provide better mechanical properties and/or greater resistance to atmospheric corrosion than conventional carbon steels.
Mild Steel vs Medium vs High-carbon Steel - Comparison The 10xx series (e.g. 1095 steel) is the most popular choice for carbon steel used in knives as well as katanas. AISI 1095 carbon steel is brittle, and has high hardness and strength. 1095 steel, when used in knives, holds a great edge and is very easy to sharpen. However, the properties of this type of steel give it a tendency to easily rust if not oiled and deliberately cared for.
Rockwell Hardness Guide What it is, How to Measure, & MoreOct 08, 2018 · A high Rockwell C rating means the tested steel is high-strength. Any value ranging in the mid-50s and above on the Rockwell C scale is considered hard. However, a high number on the RC scale doesnt necessarily mean its the best steel for a particular application.

Steel for Armour IspatGuruHigh hardness armour is the name given to a class of homogeneous steel armour which has hardness values exceeding 430 BHN (Brinell hardness number). Variable hardness steel plate introduces some advantages with varying through-thickness properties.
Super Hard (70 Rc) High Speed Steels - Knife Steel NerdsDec 02, 2019 · The higher hardness is desirable for machining of high hardness materials like high strength steel and titanium alloys, where the greater hardness difference improves performance. And when cutting materials with a higher cutting speed requiring better hot hardness. Image from 
High-speed steels, abbreviated as HSS, are a specialized class of tool steels that were named primarily for their ability to machine and cut materials at high speeds (high hot hardness). It is often used in power-saw blades and drill bits. High-speed steel is superior to the older high-carbon steel tools in that it can withstand higher temperatures without losing its temper (hardness).
