Joint downsizing with maintained performance Less space and weight wide high strength bolts
SETTING A NEW STANDARD FOR HIGH STRENGTH BOLTS
The unique B14® material is Bulten’s contribution to enable our customers to reach world class emission levels through downsizing of joints with maintained performance.
B14® basically allows you to downsize each and every fastener one dimension with maintained clamp load which reduces the weight of fasteners with 30–40%.
As clamp lengths, bushing diameters etc. are directly related to the bolt diameter you could gain additional weight savings of one to three times the weight saving of the fastener itself.
Can you afford not to evaluate the Bulten B14® potential?
- Strength > 1400 Mpa
- Ductility > 13% elongation
- Low hydrogen absorption (same as 10.9)
- 40% higher tension levels at fatigue (compared to 10.9)
- Fewer number of bolts – maintained clamp load
- Up to 40% weight saving
- Enables compact designs
- Increased clamping force
- Creep data characteristics same as 10.9 at 30% higher load
- Fatigue data characteristics same as 10.9 at 40% higher mean stress
- Suitable for thread formers such as TAPTITE 2000®
OPTIMIZED FOR CRITICAL APPLICATIONS
In order to verify the performance of the B14® material, tests have been performed by independent lab (SWEREA Kimab).
A creep test with the B14® material at 15O°C, subject to 93% ultimate tensile stress (Rm), was terminated after 1800 hours with no effect on the material.
The test concludes that B14® is a very suitable choice for bolt assemblies in critical applications such as engine and heavy loaded chassis joints.
40% STRONGER THAN THE COMPETITION
B14® shows the same characteristics as 10.9, only with the difference that it is 40% stronger! B14® shows an equally low tendency to absorb hydrogen, which means that the risk for hydrogen brittleness is at a minimum.
The combined strength and resilience of B14® comes from the fact that it is manufactured in super clean carbon steel.
A BREAKTHROUGH FOR ENVIRONMENTALLY AWARE MANUFACTURERS
Reducing weight to save energy consumption is one of the key issues for the automotive industry. B14® is an important contribution, as it makes it possible to decrease the weight of a bolt assembly – without compromising the performance of the assembly.
