Below is listed our most commonly supplied grades; please contact our sales office. Also stock is 301 stainless spring temper rolled strip.
Hi - Speed, high Speed Steel Tool Steel (made) : highly processed into the Tool Steel, carbon content high, while containing cr quantity is low (about 4%), reason burnish of Steel surface gloss darker, after heat can reach by HRc62 high hardness, resistance to rust performance not on a roll.

Heat resistant steel. AS Orlov Izobret. Mashinostr. 3, 48-49, 7/2000. The purpose of this work was to increase plasticity of heat resistant steel after aging at the 500-1300 deg C temperature and to improve its operational reliability.
Comprehensive stocks held of tool steel, including hot work, cold work and plastic mould tool steel specifications. Below we detail our most common grades. Other British Standard and international special steels and tool steels are also available, please contact our sales office.
Supplies Ball bearing steel of all types, along with carbon steel and specialty balls, to OEM's around the world. Also offers platinum balls, brass balls, gold, titanium, aluminum, carbon and plastic balls.
Carbon spring steel is held in a wide range of sizes. Detailed below are our most common specifications. Carbon steel strip and spring steel sheet is available most commonly in the hardened and tempered condition, though certain sizes are available in the annealed condition. Round and flat bar is stocked in the as rolled condition. Most spring steel specifications are held to British Standard steel specifications including BS1449 & BS970.
Alloy steel is steel alloyed with a variety of elements in total amounts of between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low alloy steels and high alloy steels. The difference between the two is somewhat arbitrary: Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0 %. Most commonly, the phrase "alloy steel" refers to "low alloy" steels.
AISI A2 Tool Steel
An air-hardening Tool Steel containing five percent chromium. Replaces the oil hardening ( 0 1 type) when safer hardening, less distortion and increased wear-resistance are required. Provides an intermediate grade between the oil hardening and the high carbon, high chromium (d 2) types.
CARBON…..1.00 MOLYBDENUM…..1.10 MANGANESE…..0.60
FORGING……………… 2000° to 2050° F, stop at 1700°F, cool slowly
NORMALIZING……… Do not normalize
ANNEALING…………. 1650° F, furnace cool, average Brinell 212
PREHEATING………… 1200° F, prior to hardening
HARDENING…………. 1775° F, air quench to 150°F
TEMPERING………….. 350° to 400° F, resulting hardness, Rockwell C 60-61
Machines easily when properly annealed to 212 Brinell. Has a factor of 65 as compared with a one percent carbon Tool Steel which has a rating of 100.
The Rockwell C hardness obtained on specimens 1 in square when quenched in air from 1800° F, and quenched in oil from 1750° F and tempered at various temperatures are as follows:
|Hardness Rockwell C|
These results may be used as a guide in tempering tools to desired hardness. However, since 1 in. specimens were used in this test, tools of heavy section or mass may be several points lower in Rockwell hardness for a given treatment.
