Strain refers to the change in shape or size of an object under stress.

Stress is defined as the force applied per unit area on an object.

Young's modulus is a measure of the stiffness of a solid material.

The spring constant is the same for all springs, regardless of their material or size.

Strain and stress are the same physical quantities.
