Spring Steel Strip

In addition to supplying spring steel strip in small quantities, we are now able to offer laser cut profiles to your drawings. We stock a wide range of materials up to 4.2mm in carbon and stainless spring steel. Furthermore we can offer small order runs. We can save you the time involved in searching for the material and a subcontractor to cut the components by offering a "one stop" solution. This can save not only time but onward transportation costs. ... Read More

Stainless spring steels are used in place of the more common high carbon and alloy spring steels where corrosion resistance is important. This will commonly occur in medical, food processing, marine and petrochemical applications. The two most available grades are 1.4310 (AISI 301) hard rolled , and BS420S37 and BS420S45 (AISI 420) hardened and tempered. 301 is an austenitic stainless with good corrosion resistance and in the hard rolled condition achieves high tensile strengths and is used commonly for applications such as feeler gauge ...

The advent of laser and waterjet cutting has revolutionised fabrication and particularly the production of complex shapes in high tensile  materials such as hardened and tempered steel strip. We supply a wide range of manufacturers who use these systems to cut out components, and the advantages of the different systems has been the subject of some discussion. I came upon this article recently by Jeff Hahn and Steve Szczesniak at the fabricator.com. Whilst lasers offer some speed advantages over ... Read More

We have asked a few times about welding high carbon steels. Whilst the process is not as staightforward as welding mild steels (below 0.25% carbon), it is possible to weld with some preparation. Alternative methods should be considered, but if this is not possible, some guidance can be found below. The main consideration is the preheating of the joint to avoid producing a brittle joint. The temperature required increases with the percentage of carbon present in the steel. Most steels used for the ... Read More

Steel Strip is annealed to:- Soften the strip for improved forming and workability To remove stresses induced during cold rolling, or uneven cooling To remove coarse grain Almost all cold rolled steel strip will have undergone the annealing process, normally prior to a final "skin pass", a final light reduction. Annealing is basically a heat treatment process which involves the heating and controlled cooling ... Read More

Spring steels are supplied either hardened or tempered or annealed to allow component manufacture prior to the hardening process. The optimum combination of hardness, strength and toughness is developed throughout the cross section of an engineering product made from steel, by means of hardening and tempering. This treatment consists of heating the work-piece to an appropriate hardening temperature, which is dependant upon the particular steel analysis involved, holding for sufficient time to ensure the whole work-piece is at temperature and then rapidly cooling ...
