MIRRALOY® TGP [4140/4150 (modified) Turned Ground & Polished, High Strength Alloy Shaft] It is offered in the heat treated, TGP condition. Typical hardness is Rockwell C 28/34. Typical tensile strength 156,000 PSI. This is a near bearing-fit shaft. Good choice of steel for machined parts requiring higher resistance to fatigue AISI 4140 Alloy Steel (UNS G41400) - AZoMSep 07, 2012 · AISI 4140 alloy steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. The hardness of the steel can be increased if it has a lower tempering temperature. For example, a tensile strength of 225 ksi can be achieved by tempering at 316°C (600°F), and tensile strength of 130 ksi can be achieved by

It is widely used across numerous industries and is an excellent material choice due to its toughness, high fatigue strength, and abrasion and impact resistance. Not many grades can match the versatility and usefulness of 4140.
One of the reasons why 4140 qualifies to be tool steel is the high content of chromium and carbon. The higher the chromium content the better. These two elements are responsible for giving this steel some extra level of hardness. The presence of molybdenum also tends to increase the corrosion resistance of this steel.

The Rockwell hardness test allows knifemakers to find a balance that promotes blade sharpness and helps the owner keep it that way. Generally, a knife with a Rockwell Hardness Scale rating of 58-62 will hold an edge better than a blade that has a lower HRC rating. Japanese SAE AISI 4140 Steel Properties, Material Heat Treatment Dec 14, 2019 · Tempering temperature of 4140 alloy steel can be from 204-649 °C (400-1200°F) after normalizing and oil quenching, and the corresponding Rockwell hardness can be obtained.
