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.

Annealing:
Annealed at 770 to 850°C. Soak thoroughly at this temperature and control furnace cool.
Hardening:
For best results harden 1.3247 in a vacuum or atmosphere furnace, or in a properly rectified salt bath. Pre heat throughly to 820 to 870°C, transfer to the high temperature furnace or salt bath. The exact hardening temperature to use depends on the type of work being treated, but in general 1.3247 tools should be hardened from the range of 1160 to 1180°C in salt, or 1180 to 1190°C in atmosphere or vacuum furnaces. After a short hold at the hardening temperature, quench the 1.3247 component without further soaking into salt at 540 to 595°C or warm oil. If salt quenched allow the 1.3247 component to equalise at the bath temperature and then complete the quench in still air. The maximum temperature of the 1.3247 tool before tempering shoud be 65°C. Larger components should not be allowed to remain at room temperature without tempering.
Tempering:
1.3247 components can be tempered between 510 to 595°C. For 1.3247 high speed steel components a minimum tempering temperature of 540°C is recommended to provide suitable relief to the hardening stresses. Triple tempering is recommended with a minimum of two hours at temperature per cycle. The 1.3247 components should be cooled in still air to room temperature between tempering treatments.
