Materials selection for any piece of equipment or a process system is rarely a simple task, unless you are exactly replicating something successful. Often engineers will have a checklist to help them narrow down the choices, eliminating groups of materials that are not suitable for various reasons. Austenitic 300 series stainless steels containing 7-35% nickel will have most if not all of the boxes checked for being suitable where a stainless steel is desired.
Food safety starts with rigorous hygiene, and nickel-containing stainless steels are the superior, reliable standard at every link of the food chain.
European nickel producers need a consistent regulatory framework. There must be coherence between different EU policy objectives with rules based on principles of sound science, risk-based approaches, full life-cycle thinking and impact assessments.
Most nickel production is destined for stainless steel. But a significant 8% is used in the production of alloy steels which are needed to deliver specific characteristics for specialised and often critical applications.
Should we be worried about there being enough nickel to supply the transition to electric vehicles and cleaner energy sources? Given its wide range of uses in important existing and emerging technologies, this is a frequently asked question.
