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.

Principal Design Features
301 is a commonly available austenitic stainless with good corrosion resistance and elevated carbon to allow for cold working to a variety of tempers. It can be obtained in the annealed, 1/4 hard, 1/2 hard, 3/4 hard, full hard, extra full hard and high yield tempers from both producers and distributors.
Applications
Automotive trim, kitchen equipment, hose clamps, wheel covers, aircraft components and a wide variety of industrial applications.
Machinability
301 is not available in bar, plate, tube, pipe or forging, therefore no information is available.
Forming
Easily formed in the annealed condition. Care must be taken in forming operations which involve deforming the material in the tempered condition as cracking and tearing can result. Intermediate annealing only serves to reduce the hardness and therefore ultimate properties.
Welding
All popular techniques may be used, however the material will lose temper in the heat affected weld zone.
Forging
Commence forging at 2000-2200 F(1093-1204 C) and finish at 1700 F(927 C).
Hot Working
While cold forming is recommended wherever feasible, forging, upsetting and other operations can be performed at 1800-2100 F. Temperatures above this range will cause scaling and a reduction in the workability of the material. Post-process annealing is required to re-attain maximum corrosion resistant properties.
Cold Working
Most common cold work methods are successful with this alloy. It should be understood however that the material will be more difficult to work than other austenitic Stainless steels due its high work hardening rate. The resulting hardening will, however, produce increases in strength and toughness which may be of value in the finished Product.
Annealing
1850-2050 F (101-1121 C) followed by rapid cooling. For thin sections air cooling is acceptable, while heavier sections should be water quenched.
Hardening
This alloy does not respond to heat treatment.
