Hardness - Wikipedia

Hardness is a measure of the resistance to localized plastic deformation induced by either mechanical indentation or abrasion. Some materials (e.g. metals) are harder than others (e.g. plastics, wood).Macroscopic hardness is generally characterized by strong intermolecular bonds, but the behavior of solid materials under force is complex; therefore, there are different measurements of hardness , what hardness of steel 3Brinell scale - WikipediaThe hardness may also be shown as XXX HB YYD 2. The XXX is the force to apply (in kgf) on a material of type YY (5 for aluminum alloys, 10 for copper alloys, 30 for steels). Thus a typical steel hardness could be written: 250 HB 30D 2. It could be a maximum or a minimum.Some results are removed in response to a notice of local law requirement.

They shall be capable ofHigh Speed Steel, Tool Steel, O1, O1 Technical DataO1 Tool Steel is the original oil-hardening, non-shrinking tool steel that can be hardened to the Rockwell C 65 range from a low austenitizing temperature. O1 is a general-purpose tool steel that is typically used in applications where alloy steels cannot provide sufficient hardness, strength, and wear resistance.

AISI 1018 Mild/Low Carbon Steel

AISI 1018 mild/low carbon steel offers a good balance of toughness, strength and ductility. AISI 1018 hot rolled steel has significant mechanical properties, improved machining characteristics and has a high Brinell hardness measure. Specific manufacturing controls are used for surface preparation, chemical composition, rolling and heating , what hardness of steel 3Damaging Objects d20PFSRD1 Add +2 for each +1 enhancement bonus of magic items. 2 The hp value given is for Medium armor, weapons, and shields.Divide by 2 for each size category of the item smaller than Medium, or multiply it by 2 for each size category larger than Medium. 3 Add 10 hp for each +1 enhancement bonus of magic items. 4 Varies by material; see Table: Substance Hardness and Hit Points.Vickers hardness test - WikipediaThe Vickers hardness test was developed in 1921 by Robert L. Smith and George E. Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials. The Vickers test is often easier to use than other hardness tests since the required calculations are independent of the size of the indenter, and the indenter can be used for all materials irrespective of hardness.

Then cool slowly with the furnace at a rate not exceeding 50°F per hour (28°C per hour) to 1000°F (538°C). Continue cooling to ambient temperature in the furnace or in air. The resultant hardness should be a maximum of 235 HBW.
