Steel express is a stockholder and supplier of Atool steel, we can supply from stock and cut to order. ATool Steel is a versatile, air hardening chromium alloy tool steel that replaces Otool steel when safer hardening, less distortion and increased wear resistance are required. AISI type Asteel is intermediate in wear resistance between Ooil-hardening tool steel and Dhigh-carbon, high-chromium tool steel. Aor Abolts are often grouped with numbers such as -70. These numbers usually signify the bolts tensile strength.

The tensile strength represents the load that this particular bolt can hold before the material breaks, cracks or becomes defective. Abolts are often used when manufacturing vehicles or vehicles parts and Abolts are best for environments where corrosion is more likely to happen such as marine equipment or exhausts. The “70” denotes the minimum tensile strength to be met by the material (actually the bolt, screw or nut after manufacture). Steels of the type A, A A A A A A and Aform air-hardening, medium alloy, cold work steels or group A steels.

Sufficient amounts of manganese, molybdenum and chromium present in group A steels provide full hardness in sections comprising thickness of at least 1mm (in.) in diameter when air cooled. Though Some Residual Magnetism Can Be Introduced When The Material Is Cold Worked. The AISI-SAE grades of tool steel is the most common scale used to identify various grades of tool steel. The selection of steel grades within a group is the prerogative of the manufacturer, unless the purchaser has specified particular steels to ISO or national standards. The most used metric class for the Ais the A-7 while with the A the A4-is most commonly used.

Corrosion resistance The Astainless steel grade bolt has a decent corrosion resistance under normal conditions such as wet surroundings, oxidising and organic acids or alkali and salt solutions.
