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:
Tool Steel
AISI H13 Hot Work Tool Steel
-
HOT ROLL FINISH
-
Machine finish) FOUR SIDES
DESCRIPTION
Combines good red hardness and abrasion resistance with the ability to resist heat checking. The most widely used hot work Tool Steel for aluminum and zinc die casting dies. Popular for extrusion press tooling because of its ability to withstand drastic cooling from high operating temperatures.
ADVANTAGES
-
High resistance to heat checking
-
Good red hardness
-
Good shock resistance
-
Good machinability
-
Good dimensional stability
-
Excellent hardenability
TYPICAL ANALYSIS
CARBON…………0.40 CHROMIUM ……….5.25 SILICON …………1.00
MOLYBDENUM ..1.25 VANADIUM ……….1.05
HEAT TREATMENT
FORGING ………………………………..2050°F to 2150°F, stop at 1650°F and cool slowly
ANNEALING ……………………………1600°F, furnace cool. Brinell 207 max
PREHEATING ……………………………1350°F soak before heating, for hardening
HARDENING …………………………….1850 °F, air quench to 150°F
TEMPERING ……………………………...1050° to 1150°F, average Rockwell C-38/46; die casting dies
should be hardened to Rockwell C-44/48. Double temper
recommended.
MACHINABILITY
May be machined without difficulty in the thoroughly annealed condition. Has a rating of 75 as compared with a one percent carbon Tool Steel, which has a rating of 100.
DIMENSIONAL STABILITY
Generally expands 0.001 in./in. of cross section when air quenched from the proper hardening temperature.
HARDENING
In a controlled atmosphere, preheat thoroughly at 1300° to 1400° F and hold for one hour per inch of greatest cross section. Quench in still air and temper immediately. May be oil quenched when maximum hardness is the primary requirement.
Note: When oil quenched, this grade is as vulnerable to cracking and has the same distortional characteristics as an oil hardening Tool Steel.
Specimens 1 in. round by 3 in. long were preheated at 1350° F. They were then transferred to a high-heat furnace and air-quenched from various temperatures ranging form 1750° to 2000° F.
TEMPERING RESULTS – DOUBLE TEMPER RECOMMENDED
Hardness tests were made on 1 in. round specimens which were air quenched from 1950° F and tempered for two hours at various temperatures. Results may be used as a tempering guide, keeping in mind that tools of heavy section or mass may be several points lower in Rockwell hardness for a given treatment.
