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:
Chemical Composition
DESCRIPTION
Alloy 825 is a Nickel-iron-chromium alloy with additions of molybdenum, copper and titanium. The alloys chemical composition provides exceptional resistance to many corrosive environments. The Nickel content is sufficient for resistance to Chloride-ion stress corrosion cracking. The nickel, combined with molybdenium and copper, also gives outstanding resistance to reducing environments such as those containing sulfuric and phosphoric acid. The molybdenium also aids resistance to pitting and crevice corrosion. The alloys Chromium content confers resistance to a variety of oxidizing substances such as nitric acid, nitrates and oxidizing salts. The titanium addition, with appropriate heat treatment, will stabilize the alloy against sensitization to intergranular corrosion.
Good resistance to stress corrosion cracking.
Satisfactory resistance to pitting and crevice corrosion.
Good resistance to oxidising and non-oxidising hot acids.
Good mechanical properties at both room and elevated temperatures up to approximately 550 deg.C (1020 deg. F).
Permission for pressure-vessel use at wall temperature up to 425 deg. C (800 deg. F).
Components such as heating coils, tanks, crates, baskets and chains in sulfuric acid pickling plants
Fuel element dissolvers-the alloy withstands the different media (sulfuric and nitric acids, caustic hydroxide etc.) used in processing
Sea water cooled heat exchangers; offshore Product piping systems tubes and components in sour gas service - resistant to chloride-ion stresscorrosion cracking
Pipelines carrying wet sulphur dioxide gas and pulp digesters in the papermaking process
Heat exchangers, evaporators, scrubbers, etc. used in phosphoric acid production
Air cooled heat exchangers used in the processing of liquid petroleum gas (LPG)
TENSILE REQUIREMENTS
Tensile Strength (KSI) 85
Yield Strength (KSI) 35
KSI can be converted to MPA (Megapascals) by multiplying by 6.895.
