For our bandsaw blades we are the largest supplier of Uddeholm steel saws in the UK with purchases of over 60 tonnes of steel per year and have supplied Uddeholm 000 as our premium brand for over 50 years.
The benchmark for top quality sawmill bandsaw blades is Uddeholm's 148 grade steel, or "UDDEHOLM 000" as it is better known. This is the steel most suitable for industrial band saw blades, as it is tough enough to allow the teeth to be swaged without cracking and breaking during work and is also suitable for stellite tipping. Swaging, in particular, creates very exacting demands on the toughness of wood cutting band saw blades as the steel has to be formed to produce the swaged tooth.
The bandsaw steel must also have good resistance to wear if the life of the teeth is to be prolonged. Since resistance to wear is dependent on hardness the steel should be as hard as possible, but not too hard as to become brittle and unable to withstand swaging. Because wood band saw blades are subject to severe impact stresses while in use the steel must have good impact resistance. The steel must also have good resistance to fatigue as the bandsaw blade must withstand repeated bending and straightening over the bandsaw wheels. The steel must also have good straightness and flatness, combined with good elasticity and resilience.
