Sign In Hard Flat - What is Pre-Hardened Flat Stock?
Hard Flats are pre-hardened flat steel plates intended for direct use. Using already hardened flat stock reduces the risk of warping and cracking. Likewise, it saves time and avoids various heat treatment steps for the steel. • Hard Flat - wear resistant steel There are several reasons why steel is hardened: • Wear resistance • Mechanical properties • Deformation |

Pre-Hardened Flat Stock - Increased Wear Resistance
Hardened steel can withstand higher stresses and wear than non-hardened steel.
Pre-Hardened Flat Stock - Enhanced Mechanical Properties
Depending on the type of steel and the specific heat treatment, the hardness, strength, and other mechanical properties of the steel can be improved.
Pre-Hardened Flat Stock - Reduction of Deformation
Hardened steel has a higher resistance to deformation under load.
WHAT IS PRE-HARDENED FLAT STOCK USED FOR?
Hardened Flat Stock is used in the industrial and commercial sectors. Particularly due to the increased hardness and strength compared to non-hardened steel, Hardened Flat Blanks are used for many applications.
Applications for hardened flat material include:
• Tool making
• Bearings and sliding guides
• Blades and knives
• Bearings and sliding guides
• Blades and knives
• Construction industry
• Agricultural equipment
• Gears and mechanical components.

Pre-Hardened Flat Stock in Toolmaking
Hardened flat stock is used in the manufacturing of tools that require wear-resistant steel. This includes cutting tools, punching tools, drills, milling cutters, as well as tools exposed to high stress.
Pre-Hardened Flat Stock for Bearings and Slide Guides
Pre-hardened flats are used for machines and equipment where parts slide or roll against each other to minimize wear. This includes gears, guide plates, guide rails, and guide strips.
Pre-Hardened Flat Stock for Blades and Knives
Hard flat is suitable for making knife blades, surgical instruments, and other sharp instruments. Hardened Plates are resistant to wear and maintain a sharp edge.
Pre-Hardened Flat Stock for Welding Constructions in the Building Industry
Hardened flats are used in the construction industry where high load-bearing capacity or wear resistance is required. This includes structures such as frames, bridges, and masts.
Pre-Hardened Flat Stock for Agricultural Equipment
Hardened blanks are also used for agricultural tools and machines that are exposed to the soil. For example, plowshares can be made from hardened steel to extend their lifespan.
Pre-Hardened Flat Stock for Transmissions and Mechanical Components
Hardened flat steel is used for transmission components or mechanical parts exposed to high friction or stress to reduce wear and increase durability. This includes components for machines such as gears, bearings, seals, or shafts.
HOW IS PRE-HARDENED FLAT STOCK MADE?
Hardened Standard Blanks undergo a special heat treatment process to increase the steel's hardness. Hardening generally involves heating the steel to a specific temperature, followed by rapid cooling. This changes the crystal structure of the steel.
Since the hardening process can make the steel more brittle, it often becomes a balancing act between increasing hardness and maintaining toughness. Hard Flat Stock undergoes additional heat treatments (tempering) to enhance toughness and reduce brittleness.
Hard Flat is tempered at least twice and hardened to a specific Rockwell hardness. This hardness varies depending on the chosen steel grade. Subsequently, the thickness of the Hardened Standardized Blanks is finely machined to decarburize the surface.
Summary - Hard Flat - Pre-Hardened Flat Stock
In summary, it can be said that Hardened Flat Stock is used wherever increased hardness and wear resistance are required compared to standard materials. The hardening itself is a heat treatment process in which the metal is heated to a certain point and then rapidly cooled to achieve the desired properties.
