I got this doubt when i was going through diffrences between pressure and stress.

Actually, it's neither - it's a tensor.
Why did I get a 'thumbs down' for being correct?!

Stress is a vector. In an anisotropic material (a material which has different properties in different directions, such as wood, which has a grain) the strain depends on the direction of the stress.
Most materials are isotropic, so the vector nature is unimportant.
Pressure is a scalar property, being the same in all directions. Area is a vector quantity, so Force (vector) = Pressure (scalar) x Area (vector). The vector representing an area is normal to the area.

Well,stress is force acting per unit area that is force/area.Now let 1/area be equal to K.Therefore stress = Kxforce.We can say that stress is the scalar product of force and scalar product of any vector is a vector.

Stress is not a vector quantity since,unlike force, the stress cannot be assigned a specific direction. force acting on the portion of a body on a specified side of e section has a definite direction

stress is a reaction to the force / pressure. Its a dependent quantity ( on strain). Therefore it has a direction and its a vector.

Stress is a scalar quantity but it is either tensile or compression which doesn't necessarily means it is a vector.
