1/8" Drill Bits McMaster-Carr

Metric sizes:Rockwell C62. Specifications Met:ASTM A681. Ready for turning in a lathe, these rods are precision ground to a tight diameter tolerance. Theyre also known as drill rod. Often used for dies, punches, and gauges, O1 tool steel is an oil-hardening material that resists wear and abrasion. 440C Martensitic Stainless Steel - Kyocera HardcoatingASTM A681 (A-2) DIN 1.2363 SAE J437 (A2) SAE J438 (A2) UNS T30102 A2 Medium Alloy, Air Hardening Cold Work Tool Steel.

:A2 Tool Steel Round Rod, Polished Finish

The A2 tool steel round rod has been precision ground and polished, meets American Society for Testing and Materials International ASTM A681 specifications, and has a precision tolerance. The A2 tool steel grade has better wear resistance than O1 and W1 tool steels, and maintains good dimensional stability when hardened in air following heat treatment. :O1 Tool Steel Sheet, Precision Ground The O1 tool steel sheet has been precision ground, meets American Society for Testing and Materials International ASTM A681 specifications, and has an oversized tolerance. The O1 tool steel grade has better machinability than A2 tool steel. It must be hardened in oil, which can be done at relatively low temperatures for good dimensional stability. A2 tool steel SKD12 1.2363 X100CrMoV5-1 cold work ASTM A681-1999 include the A2 cold work tool steel, and others cold work tool steel, hot work tool steel, high speed steel. It is standard specification of hot work tool steels, hot work tool steel, high speed steel for alloy steel tool, mould, die application, such as hot rolling or

A2 vs O1 Steel - Difference & Similarities - Otai Steel

A2 tool steel belongs to A-Group of ASTM A681, which have high hardenability and may be hardened in air. O1 tool steel must be hardened by quenching in oil.

Hardened SAE-AISI A2 is SAE-AISI A2 steel in the hardened (H) condition. The graph bars on the material properties cards below compare hardened SAE-AISI A2 to:tool steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. Tool Steel High Speed Steel Tool Steel ProductsTool Steel is stocked to tolerances per ASTM A681-08. Round bars are turned to plus tolerances to allow customers to finish to the nominal diameter. Flat bars are ground on the thickness to plus tolerances ranging from +.015 to +.090 depending on the thickness of the material. Width tolerances on flat bars is +.125/.150 and the edge is saw cut.

ASTM A681 - 08(2015) Standard Specification for Tool

1. Scope. 1.1 This specification covers the chemical, mechanical, and physical requirements for available wrought alloy tool steel products. 1.2 These products, which include hot or cold finished bar, plate, sheet, strip, rod, wire, or forgings, are normally fabricated into tools, dies, or fixtures. The selection of a material for a particular
