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.

Forging:
Heat slowly and uniformly to 1000°C. After forging cool slowly.
Heat slowly to 780°C. Slowly cool in furnace.
Hardening:
Pre heat to 600-700°C until heated through. (Austenitizing temperature 1025°C.) Continue heating to the final hardening temperature of 980-1050°C and allow the component to be heated through. Protect against decarburisation by using neutral salt bath, controlled atmosphere furnace or vacuum. Air cool or quench in oil.
Tempering:
Heat uniformly and thoroughly at the selected tempering temperatures and hold at heat for one hour per inch of total thickness. Double tempering is recommended.

Welding:
Due to the high risk of crack formation welding of 1.2083 Stainless steel should be avoided, if possible. When, howe ver welding is essential, the following serves as a guide:
A. Welding of soft annealed 1.2083 Stainless steel.
· Preheat to 300 - 500°C
· Weld at 300-500°C
· Immediately stress relieve
B. Repair welding of 1.2083 Stainless steel in hardened and tempered condition.
· Preheat to the tempering temperature (min. 200°C) previously used.
· Start welding at tempering temperature
· Re heat immediately to tempering temperature, but max. 300°C. Soaking time 3 hours.
· Cool in air to approximately 80°C.
· Re heat immediately to tempering temperature, but max. 300°C. Soaking time 3 hours.
Electrode: Hard facing electrode.
