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.

Steel mould

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 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:

655M13 is an alloy case hardening steel. Characteristics of the 655M13 steel specification are toughness arising from the use of nickel and a more uniform hardness produced by the use of chromium. 655M13 is specifically designed for carburising to give a very hard case with a strong core.

Heat Treatment - Carburising Temperature

Heat to 890°C/920°C and soak for the necessary time to obtain the desired carburised depth.

 

Single Quench Treatment:
Heat the carburised 655M13 parts to 800/820°C and quench in oil.

Double Quench Treatment:
Heat the carburised 655M13 parts to 850/880°C, cool in oil or air then re heat to 760/780C and quench in oil.

Tempering:
After hardening temper at 150°C for 2 hours minimum, and allow to cool in air to give the 655M13 tool a final surface hardness in the region of Rockwell C60/62.
