The H18 temper offers maximum strength with very limited formability, making it suitable for applications where stiffness and strength are paramount. Properties may vary depending on manufacturing processes, product form, and thickness. For critical applications, consult technical data sheets from material suppliers and conduct appropriate testing. The material can be annealed to softer tempers if additional formability is required for fabrication processes.
