Stainless Steel

Stainless Steel specifications held in the austenitic, martensitic and precipitation hardening varieties. Stocks are held in British Standard and International standards. Below is listed our most commonly supplied grades; please contact our sales office. Also stock is 301 stainless spring temper rolled strip.

Hi-Steel HSLA-80

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.

Mould Steel

Steel mould and Steel mould suppliers, global delivery, stock supply Steel mould steels.

Heat Resistant Steel

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.

Tool Steel

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.

Ball Bearing Steel

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.

Spring Steel

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 and Carbon Steel

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 %.[1][2] Most commonly, the phrase "alloy steel" refers to "low alloy" steels.

AISI A2 Tool Steel

  • Numbers: 2011030505
  • Model: AISI A2
  • Producers: China
  • Update time: 2011.03.05

Product Description:



AISI A2 Air Hardening Tool Steel

  • (Machine finish) T & B WITH SAW-CUT EDGES
  • (Machine finish) FOUR SIDES


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.


  • Low distortion in heat-treatment
  • Good machinability
  • High abrasion-resistance and hardness
  • Good toughness for severe service
  • Deep hardening properties in large sections





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
Temperatures F
1800 F
1750 F
None 64 65
300 62 62.50
400 60 61
500 56 57.50
600 56 56
700 56 56
800 56 56
900 56 56
1000 56 55
1100 50 50
1200 43 45
1300 34 34

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.
