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.
Free Cutting Steel
Cutting steel (free cutting steel) in the steel added a certain amount of one or more of sulfur, phosphorus, lead, calcium, selenium, tellurium and other cutting elements, in order to improve the cutting of steel. Also known as the automatic machining of steel, referred to as auto steel. Such steel can be larger at higher cutting speeds and cutting depth.

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.
Valve Steel
Single Figures are Maximums 0.47/0.57 C, 8.00/10.00 Mn, 0.25 Si, 20.00/22.00 Cr, 3.2/4.5 Ni, 0.38/0.50 N, Bal. Fe A nitrogen-strengthened, austenitic alloy. Has been used in heavy-duty valve applications for internal combustion engines.

Mf : 86°F (30°C)
1925°F+ /-50°F (1050°C +/-25°C) – 30 min up to 1 hour.
air cooling / oil quenching below 76°F (25°C)
The highest mechanical properties are obtained with the following heat treatment : 896°F (480°C) – 1 hour – air cooling. Higher ductilities are obtained when using higher aging temperatures up to 1148°F (620°C).
Alloy 17-4 PH can be welded by the following welding processes: SMAW, GTAW, PAW and GMAW. SAW should not be used without preliminary testing (to check freedom of cracks and toughness of the weld metal).
Alloy 17-4 PH can be machined in both solution treated and precipitation hardened conditions. Machining condition may vary according to the hardness of the material. High speed steel tools or preferably carbide tools with standard lubrification are normally used. If very stringent tolerances are required, it is necessary to take into account the dimensional changes during heat treatment
