Best Limitations Of Brinell Hardness Test

Starrett Air-Hardened A2 Tool Steel Flat Stock, Precision Ground, Standard Tolerance, ASTM A681, 1 1/2\ Width, 1/8\ Thick, 18\ Length

Ideal for a wide variety of parts that don't require more expensive heat treated steels, such as stripper plates, jigs, fixtures, machine and component parts, templates, etc.
This steel can be carburized or case hardened After hardening, its physical properties, especially tensile strength, yield point, and Brinell hardness, are substantially higher.
The Starrett Company uses its own ground flat stock for many of its precision tool parts.
Full-length identification eliminates confusion with other steels.
Starrett A2 Tool Steel precision ground flat stock is a 20 carbon fine-grained, killed steel, which can be carburized or case hardened very similar to AISI 1018.

★ 【Main Function】The hardness of coating film is a necessary index for quality identification in coating manufacturing and coating application (coating table) industry. Pencil scratch test for film hardness is a widely used test method in the world since 1980s.
★ 【Wide Application】It is applicable to film hardness test. The instrument is mechanical, three points contact the tested surface (two points are wheels and one point is pencil core). It always ensures that the tested film forms an included angle of 45 degrees, and pushes the instrument to move horizontally with force, so as to complete the test process and determine the resistance of the film to deformation. The method is designed and manufactured according to manual operation, expresse.
★ 【Wide Application】This instrument is designed and manufactured in accordance with the manual operation method in Article 2 and 3 of the national standard "pencil test method for film hardness" GB6379-86. The instrument can be used in the laboratory, can also be applied to the construction site, and can identify the hardness of the film in any direction..

This set includes 8 Mohs' Hardness Points from Mohs' 2 through Mohs' 9, nicely mounted in nickel-plated Brass, color-coded, number-stamped, and double-ended Pin Vises, along with two Hardness Plates of Mohs' 3.5 and 5.5, a Streak Plate, a Magnet, and a 100x Sharpening Stone, enhanced by Instructions, Table of Minerals sorted by Mohs' Hardness, all neatly packaged in a compact, Wooden Case..
To perform a scratch test, select a numbered Hardness point, and try to scratch a flat, smooth surface of the mineral. For example, if the number 6 point scratches your mineral, but the number 5 point does not, then your mineral has a Mohs' Hardness value of about 5.5. This is an important mineral identifying criteria..
The Hardness Points are made of Metals and Alloys of equivalent Mohs' Hardness as the mineral standards, so the points will not break off, and they can easily be r....
