From the Home page, use the Product Selector or Materials section to access key technical details for the metals we use. In addition, Frame Builders and Designers can access our current tubing profiles as a PDF file directly from our website in the Materials section. Our larger customers have their own (proprietary) tube designs which are custom drawn specifically for them.
What is special about air-hardening steels? [+]
The chemistry of air-hardening steels like our 853 and 631 means that not only are they stronger than typical chrome-alloy 4130 type steels, but after TIG o r MIG welding, the heat-affected zone (HAZ) will be significantly stronger due to the grain structure formed on cooling in air. The positive result from this is a higher fatigue life for the joint - usually 30-60% better than an equivalent Cr-Mo joint. So less material can be used to achieve a particular target fatigue performance.
