Hardening and Tempering is a thermal process that strengthens steel through a controlled heating and cooling process Hardened and tempered steel strip, is used in many applications including saws, cutting tools as well as springs.

This process will result in improved mechanical properties and give a tougher more durable product. The hardening process involves heating the steel to above the critical transformation temperature for the given grade and then rapidly cooling. Whilst this process achieves the  highest mechanical strengths and hardness's, steel in this condition is extremely brittle and therefore requires further treatment in the form of tempering. This consists of reheating the steel to a lower temperature and holding the steel at the given temperature for a given period of time. As with traditional annealing (used to soften steels) this process is conducted in an inert atmosphere to avoid oxidation .The exact temperatures and processing times vary with given grades of steel and the process is very specialised.

Having recognised a “gap” in the steel supply market BSS Steelstrip is now able to offer small quantities of spring steel strip from stock.

Whilst steel mills regularly insist on minimum order quantities of up to 5 tons, and stockholders upwards of a ton, we have recognised the need of smaller engineering companies who may require as little as a single sheet to complete a project, or to replace a part in an ageing piece of plant.

It can be frustrating and time consuming for an engineer to spend hours on the telephone trying to source small quantities of spring steel, only to find the supplier loses interest the moment he realises the small quantity involved. To be honest it’s as a big a problem often for the supplier as for the customer! Not for us!

Here at BSS we won’t turn you away, we are pleased to hear from you and pleased to help. We can supply from 1 sheet to half a ton. Just email us your enquiry; we will make our best offer. Material is delivered worldwide by TNT with “online tracking”, and to make the process even easier you can pay by credit card!

Sourcing small quantities of spring steel need not be a “painful” experience call us on 01709 530591 or email us today at
