Galling is serious…but there are solutions
Galling is a form of wear that is caused by metal surfaces in gliding contact with one other, such as the potentially hundreds of stainless steel bolts and fasteners holding production equipment and its moving parts together. With potentially disastrous effects resulting from galled fasteners seizing or even being subject to a fatigue breakage, industry players are advised to counter this threat.
At the heart of the stainless steel industry
On the 30th of September, John Rowe will be leaving the offices of the International Stainless Steel Forum for the last time, having handed over the role of Secretary General to Tim Collins. In a joint interview, SSWN asked John and Tim to outline the role of the Secretary General and to touch on the challenges facing the stainless industry.
Precision stainless steel consumption growing
The global market for precision stainless steel (also known as thin strip) is expected to expand 1.5x in terms of market volume by the end of 2029. East Asia currently accounts for over 50% of consumption and this is expected to grow.
3D Printing for the marine industry
The marine industry in general has been slow to embrace the 3D printing concept. The use of continuous liquid metal deposition under computer numerical control has created opportunities to produce complex shapes such as forgings and castings whilst avoiding the need for expensive tooling and the time delays in fabricating moulds. Notwithstanding this slow start, development work at Delft Technical University in 2017 has led to the production of the world’s first metal deposited marine propeller.
MaX: The new normal for ‘Body-in-White’
Starting in the 1990s and accelerating ever since the automobile industry has been defined by a revolution in innovation. From the internal combustion engine to the complete electric vehicle and the in-between hybrid, power train technologies are in a state of constant evolution. But innovation doesn’t stop with the engine.
