A Pontryagin-Thom type construction for Stein factorizations of fold maps of 3-manifolds into the plane is given. It is applied to compute the cobordism group of Stein factorizations of fold maps of oriented 3-manifolds into the plane and the oriented cobordism group of fold maps of 3-manifolds into the plane. By the same methods the oriented bordism groups are computed.
