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 %.[1][2] Most commonly, the phrase "alloy steel" refers to "low alloy" steels.
1.2080 X210Cr12 Tool Steel
1.2080 X210Cr12 is an air hardening, high carbon high chromium, alloy Tool Steel with excellent resistance to abrasion and wear. 1.2080 X210Cr12 has good through hardening characteristics combined with dimensional stability with high resistance to tempering. |

Forging:
Heat slowly and uniformly to 700°C then more rapidly to 900/1050°C. After forging cool slowly, preferably in a furnace.
Annealing:
Anneal at 900°C and slow furnace cool. Hardness after annealing will be approx. 225 brinell.
Stress Relieving:
If the machining operations have been heavy or if the 1.2080 tool has an unbalanced section, remove stresses before hardening by heating up to 700°C, equalise, cool slowly.
Hardening:
Pre heat slowly to 750/800°C and thoroughly soak. Continue heating the 1.2080 component to the final hardening temperature of 950/1000°C and allow the 1.2080 component to be heated through. Cool in air or quench in oil.
Tempering:
Heat uniformly and thoroughly at the selected tempering temperature and hold for at least one hour per inch of total thickness. Double tempering should be carried out with intermediate cooling to room temperature.

Hard Chrome Plating:
After hard chromium plating tempering of 1.2080 Tool Steel is recommended at 180°C for 4 hours to avoid hydrogen embrittlement. Tempering is to be performed immediately after chromium plating.
Welding:
Due to the high risk of crack formation welding of 1.2080 Tool Steel should be avoided, if possible. When, however welding is essential, the following serves as a guide:
A. Welding of soft annealed 1.2080 Tool Steel
· Preheat to 300 - 500°C
· Weld at 300-500°C
· Immediately stress relieve
Electrode: Cr-Mo alloy electrode for welding structural steel.
B. Welding in connection with hardening of soft annealed 1.2080 Tool Steel.
· Heat to austenitizing temperature.
· Cool to approx. 500°C
· Weld at approx. 500°C
· Cool to approx. 100°C in the same way as at normal hardening, then temper to desired hardness. Double tempering will reduce the risk of crack formation.
Electrode: Hard facing electrode.
C. Repair welding of 1.2080 Tool Steel in hardened and tempered condition.
· Preheat to the tempering temperature (min. 200°C) previously used.
· Weld at tempering temperature.
· Heat immediately to tempering temperature, but max. 300°C. Soaking time 3 hours.
· Cool in air to approx. 80°C.
· Heat to tempering temperature. Soaking time 2 hours.
Electrode: Hard facing electrode.
