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.

Product Description:

722M24 is a chromium-molybdenum nitriding steel usually supplied in the hardened and tempered condition. 722M24 offers high wear resistance together with good toughness and ductility. 722M24 is characterised by its suitability for nitriding, which can give a hard wear resistant core in the range of  61-65Rc. The relatively low temperature of the nitriding process produces 722M24components with a scale free surface, and minimum distortion.
