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 - 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.
Steel mould and Steel mould suppliers, global delivery, stock supply Steel mould steels.
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.
SAE 8620, AISI 8620
8620 is a low alloy case hardening steel which is supplied to American standards SAE 8620 and AISI 8620. 8620 can be carburised, which will achieve a tough core with a hard wear resistant case. 8620 provides a combination of toughness and wear resistance. 8620 is supplied in either the as rolled or annealed condition for subsequent case hardening. |

Mechanical properties are not stated in AISI 8620 or SAE 8620 as standard. The mechanical properties information for AISI 8620 / SAE 8620 is provided below as a guida. A test piece of 19mm diameter AISI 8620 / SAE 8620 is blank carburised for at least one hour at a temperature of between 880-930°C and allowed to cool at room temperature. The test piece of AISI 8620 / SAE 8620 is then re treated to 820-840°C and quenched in oil.
